Authentication bypass | Breaking Cybersecurity News | The Hacker News

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday  added  two security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog due to active exploitation, while removing five bugs from the list due to lack of adequate evidence. The vulnerabilities newly added are below - CVE-2023-42793  (CVSS score: 9.8) - JetBrains TeamCity Authentication Bypass Vulnerability CVE-2023-28229  (CVSS score: 7.0) - Microsoft Windows CNG Key Isolation Service Privilege Escalation Vulnerability CVE-2023-42793 relates to a  critical authentication bypass vulnerability  that allows for remote code execution on TeamCity Server. Data gathered by GreyNoise has revealed exploitation attempts targeting the flaw from  74 unique IP addresses  to date. On the other hand, CVE-2023-28229 is a  high-severity flaw  in the Microsoft Windows Cryptographic Next Generation (CNG) Key Isolation Service that allows an attacker to gain specific limited SYSTEM privileges. There are curren

Security researchers have disclosed two new vulnerabilities affecting Schneider Electric Modicon programmable logic controllers (PLCs) that could allow for authentication bypass and remote code execution. The flaws, tracked as  CVE-2022-45788  (CVSS score: 7.5) and  CVE-2022-45789  (CVSS score: 8.1), are part of a  broader collection  of  security defects  tracked by Forescout as OT:ICEFALL. Successful exploitation of the bugs could enable an adversary to execute unauthorized code, denial-of-service, or disclosure of sensitive information. The cybersecurity company said the shortcomings can be chained by a threat actor with known flaws from other vendors (e.g.,  CVE-2021-31886 ) to achieve deep lateral movement in operational technology (OT) networks. "Deep lateral movement lets attackers gain deep access to industrial control systems and cross often overlooked security perimeters, allowing them to perform highly granular and stealthy manipulations as well as override funct

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

Citrix has released  security updates  to address a critical authentication bypass flaw in the application delivery controller (ADC) and Gateway products that could be exploited to take control of affected systems. Successful exploitation of the issues could enable an adversary to gain authorized access, perform remote desktop takeover, and even circumvent defenses against login brute-force attempts under specific configurations. CVE-2022-27510  - Unauthorized access to Gateway user capabilities CVE-2022-27513  - Remote desktop takeover via phishing CVE-2022-27516  - User login brute-force protection functionality bypass The following supported versions of Citrix ADC and Citrix Gateway are affected by the flaws - Citrix ADC and Citrix Gateway 13.1 before 13.1-33.47  Citrix ADC and Citrix Gateway 13.0 before 13.0-88.12  Citrix ADC and Citrix Gateway 12.1 before 12.1.65.21 Citrix ADC 12.1-FIPS before 12.1-55.289 Citrix ADC 12.1-NDcPP before 12.1-55.289 Exploitation, howe

VMware has patched five security flaws affecting its  Workspace ONE Assist  solution, some of which could be exploited to bypass authentication and obtain elevated permissions. Topping the list are three critical vulnerabilities tracked as CVE-2022-31685, CVE-2022-31686, and CVE-2022-31687. All the shortcomings are rated 9.8 on the CVSS vulnerability scoring system. CVE-2022-31685 is an authentication bypass flaw that could be abused by an attacker with network access to VMware Workspace ONE Assist to obtain administrative access without the need to authenticate to the application. CVE-2022-31686 has been described by the virtualization services provider as a "broken authentication method" vulnerability, and CVE-2022-31687 as a "Broken Access Control" flaw. "A malicious actor with network access may be able to obtain administrative access without the need to authenticate to the application," VMware  said  in an advisory for CVE-2022-31686 and CVE-202

Microsoft on Tuesday said it addressed an authentication bypass vulnerability in  Jupyter Notebooks  for Azure Cosmos DB that enabled full read and write access. The tech giant said the problem was introduced on August 12, 2022, and rectified worldwide on October 6, 2022, two days after responsible disclosure from Orca Security, which dubbed the flaw  CosMiss . "In short, if an attacker had knowledge of a Notebook's 'forwardingId,' which is the UUID of the Notebook Workspace, they would have had full permissions on the Notebook without having to authenticate, including read and write access, and the ability to modify the file system of the container running the notebook," researchers Lidor Ben Shitrit and Roee Sagi said. This container modification could ultimately pave the way for obtaining remote code execution in the Notebook container by overwriting a Python file associated with the  Cosmos DB Explorer  to spawn a reverse shell. Successful exploitation

Fortinet has privately warned its customers of a security flaw affecting FortiGate firewalls and FortiProxy web proxies that could potentially allow an attacker to perform unauthorized actions on susceptible devices. Tracked as CVE-2022-40684 (CVSS score: 9.6), the critical flaw relates to an authentication bypass vulnerability that may permit an unauthenticated adversary to carry out arbitrary operations on the administrative interface via a specially crafted HTTP(S) request. The issue impacts the following versions, and has been addressed in FortiOS versions  7.0.7  and  7.2.2 , and FortiProxy versions 7.0.7 and 7.2.1 released this week: FortiOS - From 7.0.0 to 7.0.6 and from 7.2.0 to 7.2.1 FortiProxy - From 7.0.0 to 7.0.6 and 7.2.0 "Due to the ability to exploit this issue remotely, Fortinet is strongly recommending all customers with the vulnerable versions to perform an immediate upgrade," the company  cautioned  in an alert shared by a security researcher w

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday  added  two flaws to its  Known Exploited Vulnerabilities Catalog , citing evidence of active exploitation. The two high-severity issues relate to weaknesses in Zimbra Collaboration, both of which could be chained to achieve unauthenticated remote code execution on affected email servers - CVE-2022-27925  (CVSS score: 7.2) - Remote code execution (RCE) through mboximport from authenticated user (fixed in  versions  8.8.15 Patch 31 and 9.0.0 Patch 24 released in March) CVE-2022-37042  - Authentication bypass in MailboxImportServlet (fixed in  versions  8.8.15 Patch 33 and 9.0.0 Patch 26 released in August) "If you are running a Zimbra version that is older than Zimbra 8.8.15 patch 33 or Zimbra 9.0.0 patch 26 you should update to the latest patch as soon as possible," Zimbra  warned  earlier this week. CISA has not shared any information on the attacks exploiting the flaws but cybersecurity fi

Malicious actors can gain unauthorized access to users' online accounts via a new technique called "account pre-hijacking," latest research has found. The attack takes aim at the account creation process that's ubiquitous in websites and other online platforms, enabling an adversary to perform a set of actions before an unsuspecting victim creates an account in a target service. The study was led by independent security researcher Avinash Sudhodanan in collaboration with Andrew Paverd of the Microsoft Security Response Center (MSRC). Pre-hijacking banks on the prerequisite that an attacker is already in possession of a unique identifier associated with a victim, such as an email address or phone number, information which can be obtained either from scraping the target's social media accounts or credential dumps circulating on the web as a result of countless data breaches. The attacks can then play out in five different ways, including the use of the same em

Atlassian has published a security advisory warning of a critical vulnerability in its Jira software that could be abused by a remote, unauthenticated attacker to circumvent authentication protections. Tracked as  CVE-2022-0540 , the flaw is rated 9.9 out of 10 on the CVSS scoring system and resides in Jira's authentication framework, Jira Seraph. Khoadha of Viettel Cyber Security has been credited with discovering and reporting the security weakness. "A remote, unauthenticated attacker could exploit this by sending a specially crafted HTTP request to bypass authentication and authorization requirements in WebWork actions using an affected configuration," Atlassian  noted . The flaw affects the following Jira products - Jira Core Server, Jira Software Server and Jira Software Data Center: All versions before 8.13.18, 8.14.x, 8.15.x, 8.16.x, 8.17.x, 8.18.x, 8.19.x, 8.20.x before 8.20.6, and 8.21.x Jira Service Management Server and Jira Service Management Data Cent

A week after VMware released patches to remediate eight security vulnerabilities in VMware Workspace ONE Access, threat actors have begun to actively exploit one of the critical flaws in the wild. Tracked as  CVE-2022-22954 , the security shortcoming relates to a remote code execution vulnerability that stems from server-side template injection in VMware Workspace ONE Access and Identity Manager. The bug is rated 9.8 in severity. "A malicious actor with network access can trigger a server-side  template injection  that may result in remote code execution," the company  noted  in its advisory. The virtualization services provider has since revised its bulletin to warn customers of confirmed exploitation of CVE-2022-22954 occurring in the wild. Cybersecurity firm Bad Packets also  corroborated  that it detected attempts to weaponize the vulnerability. Source:  Bad Packets It's worth noting that the patches shipped last week address seven more vulnerabilities in VMwar

Apple recently paid Indian vulnerability researcher Bhavuk Jain a huge $100,000 bug bounty for reporting a highly critical vulnerability affecting its ' Sign in with Apple ' system. The now-patched vulnerability could have allowed remote attackers to bypass authentication and take over targeted users' accounts on third-party services and apps that have been registered using 'Sign in with Apple' option. Launched last year at Apple's WWDC conference, ' Sign in with Apple ' feature was introduced to the world as a privacy-preserving login mechanism that allows users to sign up an account with 3rd-party apps without disclosing their actual email addresses (also used as Apple IDs). In an interview with The Hacker News, Bhavuk Jain revealed that the vulnerability he discovered resided in the way Apple was validating a user on the client-side before initiating a request from Apple's authentication servers. For those unaware, while authenticating

Mitron (means "friends" in Hindi), you have been fooled again! Mitron is not really a 'Made in India' product, and the viral app contains a highly critical, unpatched vulnerability that could allow anyone to hack into any user account without requiring interaction from the targeted users or their passwords. I am sure many of you already know what TikTok is, and those still unaware, it's a highly popular video social platform where people upload short videos of themselves doing things like lip-syncing and dancing. The wrath faced by Chinese-owned TikTok from all directions—mostly due to data security and ethnopolitical reasons—gave birth to new alternatives in the market, one of which is the Mitron app for Android. Mitron video social platform recently caught headlines when the Android app crazily gained over 5 million installations and 250,000 5-star ratings in just 48 days after being released on the Google Play Store. Popped out of nowhere, Mitron i

Attention WordPress users! Your website could easily get hacked if you are using " Ultimate Addons for Beaver Builder ," or " Ultimate Addons for Elementor " and haven't recently updated them to the latest available versions. Security researchers have discovered a critical yet easy-to-exploit authentication bypass vulnerability in both widely-used premium WordPress plugins that could allow remote attackers to gain administrative access to sites without requiring any password. What's more worrisome is that opportunistic attackers have already started exploiting this vulnerability in the wild within 2 days of its discovery in order to compromise vulnerable WordPress websites and install a malicious backdoor for later access. Both vulnerable plugins, made by software development company Brainstorm Force, are currently powering over hundreds of thousands of WordPress websites using Elementor and Beaver Builder frameworks, helping website admins and de

OpenBSD, an open-source operating system built with security in mind, has been found vulnerable to four new high-severity security vulnerabilities, one of which is an old-school type authentication bypass vulnerability in BSD Auth framework. The other three vulnerabilities are privilege escalation issues that could allow local users or malicious software to gain privileges of an auth group, root, as well as of other users, respectively. The vulnerabilities were discovered and reported by Qualys Research Labs earlier this week, in response to which OpenBSD developers released security patches for OpenBSD 6.5 and OpenBSD 6.6 just yesterday—that's in less than 40 hours. Here's a brief explanation of all four security vulnerabilities in OpenBSD—a free and open-source BSD-based Unix-like operating system—along with their assigned CVE identifiers OpenBSD Authentication Bypass (CVE-2019-19521) The authentication bypass vulnerability resides in the way OpenBSD's auth

Security researchers have discovered multiple critical vulnerabilities in a popular IPTV middleware platform that is currently being used by more than a thousand regional and international online media streaming services to manage their millions of subscribers. Discovered by security researchers at CheckPoint , the vulnerabilities reside in the administrative panel of Ministra TV platform, which if exploited, could allow attackers to bypass authentication and extract subscribers' database, including their financial details. Besides this, the flaws could also allow attackers to replace broadcast and steam any content of their choice on the TV screens of all affected customer networks. Ministra TV platform, previously known as Stalker Portal, is a software written in PHP that works as a middleware platform for media streaming services for managing Internet Protocol television (IPTV), video-on-demand (VOD) and over-the-top (OTT) content, licenses and their subscribers. Deve

Security researchers have discovered an authentication bypass vulnerability in Western Digital's My Cloud NAS devices that potentially allows an unauthenticated attacker to gain admin-level control to the affected devices. Western Digital's My Cloud (WD My Cloud) is one of the most popular network-attached storage (NAS) devices which is being used by businesses and individuals to host their files, as well as backup and sync them with various cloud and web-based services. The WD My Cloud devices let users not only share files in a home network but its private cloud feature also allows them to access their data from anywhere around the world at any time. However, security researchers at Securify have discovered an authentication bypass vulnerability on the WD My Cloud NAS boxes that could allow unauthenticated attackers with network access to the device to escalate their privileges to admin-level without needing to provide a password. This would eventually allow attack

A critical authentication bypass vulnerability has been discovered in one of the biggest identity-as-a-service platform Auth0 that could have allowed a malicious attacker to access any portal or application, which are using Auth0 service for authentication. Auth0 offers token-based authentication solutions for a number of platforms including the ability to integrate social media authentication into an application. With over 2000 enterprise customers and managing 42 million logins every day and billions of login per month, Auth0 is one of the biggest identity platforms. While pentesting an application back in September 2017, researchers from security firm Cinta Infinita discovered a flaw ( CVE-2018-6873 ) in Auth0's Legacy Lock API , which resides due to improper validation of the JSON Web Tokens (JWT) audience parameter. Researchers successfully exploited this issue to bypass login authentication using a simple cross-site request forgery (CSRF/XSRF) attack against the

Payment services provider PayPal is vulnerable to an authentication restriction bypass vulnerability , which could allow an attacker to bypass a filter or restriction of the online-service to get unauthorized access to a blocked users ' PayPal account. The security vulnerability actually resides in the mobile API authentication procedure of the PayPal online-service , which doesn't check for the blocked and restricted PayPal accounts. HOW THE VULNERABILITY WORKS In case if a PayPal user enters a wrong username or password combination several times in an effort to access the account, then for the security reasons, PayPal will restrict the user from opening or accessing his/her account on a computer until the answers to a number of security questions is provided. However, if the same user, at the same time switches to a mobile device and tries accessing the temporarily closed PayPal account with the right credentials via an official PayPal mobile app client through t

Likes.com, one of the emerging social networking site and popular image browsing platform, is found vulnerable to several critical vulnerabilities that could allow an attacker to completely delete users' account in just one click. Likes.com is a social networking website that helps you to connect with people you like and make new friends for free. Just like any other social place, users can always follow their favorite tag or people who catch their fancy. It is much easier to use and is designed for those who want to look at pictures different people upload. An independent security researcher Mohamed M. Fouad from Egypt has found a series of critical security vulnerabilities in the Likes website that really pose danger to its users. The vulnerabilities he found not only have capability to add any post, comment to users' account as well as delete users' account, but the vulnerabilities can be escalated to deface entire website by posting malicious URLs and delete all use

At the beginning of this year, we reported about the secret backdoor 'TCP 32764' discovered in several routers including, Linksys, Netgear, Cisco and Diamond that allowed an attacker to send commands to the vulnerable routers at TCP port 32764 from a command-line shell without being authenticated as the administrator. The Reverse-engineer from France Eloi Vanderbeken , who discovered this backdoor has found that although the flaw has been patched in the latest firmware release, but SerComm has added the same backdoor again in another way. To verify the released patch, recently he downloaded the patched firmware version 1.1.0.55 of Netgear DGN1000 and unpacked it using binwalk tool. He found that the file 'scfgmgr' which contains the backdoor is still present there with a new option " -l ", that limits it only for a local socket interprocess communication (Unix domain socket), or only for the processes running on the same device.
