Juniper Networks has released out-of-band security updates to address a critical security flaw that could lead to an authentication bypass in some of its routers. The vulnerability, tracked as CVE-2024-2973, carries a CVSS score of 10.0, indicating maximum severity. "An Authentication Bypass Using an Alternate Path or Channel vulnerability in Juniper Networks Session Smart Router or Conductor running with a redundant peer allows a network based attacker to bypass authentication and take full control of the device," the company said in an advisory issued last week. According to Juniper Networks, the shortcoming affects only those routers or conductors that are running in high-availability redundant configurations. The list of impacted devices is listed below - Session Smart Router (all versions before 5.6.15, from 6.0 before 6.1.9-lts, and from 6.2 before 6.2.5-sts) Session Smart Conductor (all versions before 5.6.15, from 6.0 before 6.1.9-lts, and from 6.2 before 6.2.5-sts) W

ASUS has shipped software updates to address a critical security flaw impacting its routers that could be exploited by malicious actors to bypass authentication. Tracked as CVE-2024-3080 , the vulnerability carries a CVSS score of 9.8 out of a maximum of 10.0. "Certain ASUS router models have authentication bypass vulnerability, allowing unauthenticated remote attackers to log in the device," according to a description of the flaw shared by the Taiwan Computer Emergency Response Team / Coordination Center (TWCERT/CC). Also patched by the Taiwanese company is a high-severity buffer overflow flaw tracked as CVE-2024-3079 (CVSS score: 7.2) that could be weaponized by remote attackers with administrative privileges to execute arbitrary commands on the device. In a hypothetical attack scenario, a bad actor could fashion CVE-2024-3080 and CVE-2024-3079 into an exploit chain in order to sidestep authentication and execute malicious code on susceptible devices. Both the shor

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,

A maximum-severity security flaw has been disclosed in the  TP-Link Archer C5400X gaming router  that could lead to remote code execution on susceptible devices by sending specially crafted requests. The vulnerability, tracked as  CVE-2024-5035 , carries a CVSS score of 10.0. It impacts all versions of the router firmware including and prior to 1_1.1.6. It has been patched in  version 1_1.1.7  released on May 24, 2024. "By successfully exploiting this flaw, remote unauthenticated attackers can gain arbitrary command execution on the device with elevated privileges," German cybersecurity firm ONEKEY  said  in a report published Monday. The issue is rooted in a binary related to radio frequency testing "rftest" that's launched on startup and exposes a network listener on TCP ports 8888, 8889, and 8890, thus allowing a remote unauthenticated attacker to achieve code execution. While the network service is designed to only accept commands that start with "

A severity flaw impacting industrial cellular routers from Milesight may have been actively exploited in real-world attacks, new findings from VulnCheck reveal. Tracked as  CVE-2023-43261  (CVSS score: 7.5), the vulnerability has been described as a case of information disclosure that affects UR5X, UR32L, UR32, UR35, and UR41 routers before version 35.3.0.7 that could enable attackers to access logs such as httpd.log as well as other sensitive credentials. As a result, this could permit remote and unauthenticated attackers to gain unauthorized access to the web interface, thereby making it possible to configure VPN servers and even drop firewall protections. "This  vulnerability  becomes even more severe as some routers allow the sending and receiving of SMS messages," security researcher Bipin Jitiya, who discovered the issue,  said  earlier this month. "An attacker could exploit this functionality for fraudulent activities, potentially causing financial harm to the

A new malware strain has been found covertly targeting small office/home office (SOHO) routers for more than two years, infiltrating over 70,000 devices and creating a botnet with 40,000 nodes spanning 20 countries. Lumen Black Lotus Labs has dubbed the malware  AVrecon , making it the third such strain to focus on SOHO routers after  ZuoRAT  and  HiatusRAT  over the past year. "This makes AVrecon one of the largest SOHO router-targeting botnets ever seen," the company  said . "The purpose of the campaign appears to be the creation of a covert network to quietly enable a range of criminal activities from password spraying to digital advertising fraud." A majority of the infections are located in the U.K. and the U.S., followed by Argentina, Nigeria, Brazil, Italy, Bangladesh, Vietnam, India, Russia, and South Africa, among others. AVrecon was  first highlighted  by Kaspersky senior security researcher Ye (Seth) Jin in May 2021, indicating that the malware has

Taiwanese company ASUS on Monday  released firmware updates  to address, among other issues, nine security bugs impacting a wide range of router models. Of the nine security flaws, two are rated Critical and six are rated High in severity. One vulnerability is currently awaiting analysis. The list of impacted products are GT6, GT-AXE16000, GT-AX11000 PRO, GT-AXE11000, GT-AX6000, GT-AX11000, GS-AX5400, GS-AX3000, XT9, XT8, XT8 V2, RT-AX86U PRO, RT-AX86U, RT-AX86S, RT-AX82U, RT-AX58U, RT-AX3000, TUF-AX6000, and TUF-AX5400. Topping the list of fixes are  CVE-2018-1160  and  CVE-2022-26376 , both of which are rated 9.8 out of a maximum of 10 on the CVSS scoring system. CVE-2018-1160 concerns a nearly five-year-old out-of-bounds write bug in Netatalk versions before 3.1.12 that could allow a remote unauthenticated attacker to achieve arbitrary code execution. CVE-2022-26376 has been described as a memory corruption vulnerability in the Asuswrt firmware that could be triggered by mean

Security vulnerabilities have been disclosed in Netcomm and TP-Link routers, some of which could be weaponized to achieve remote code execution. The flaws, tracked as  CVE-2022-4873  and  CVE-2022-4874 , concern a case of stack-based buffer overflow and authentication bypass and impact Netcomm router models NF20MESH, NF20, and NL1902 running firmware versions earlier than R6B035 . "The two vulnerabilities, when chained together, permit a remote, unauthenticated attacker to execute arbitrary code," the CERT Coordination Center (CERT/CC)  said  in an advisory published Tuesday. "The attacker can first gain unauthorized access to affected devices, and then use those entry points to gain access to other networks or compromise the availability, integrity, or confidentiality of data being transmitted from the internal network." Security researcher  Brendan Scarvell  has been credited with discovering and reporting the issues in October 2022. In a related developme

Cisco has warned of two security vulnerabilities affecting end-of-life (EoL) Small Business RV016, RV042, RV042G, and RV082 routers that it said will not be fixed, even as it acknowledged the public availability of proof-of-concept (PoC) exploit. The  issues  are rooted in the router's web-based management interface, enabling a remote adversary to sidestep authentication or execute malicious commands on the underlying operating system. The most severe of the two is CVE-2023-20025 (CVSS score: 9.0), which is the result of improper validation of user input within incoming HTTP packets. A threat actor could exploit it remotely by sending a specially crafted HTTP request to vulnerable routers' web-based management interface to bypass authentication and obtain elevated permissions. The lack of adequate validation is also the reason behind the second flaw tracked as CVE-2023-20026 (CVSS score: 6.5), permitting an attacker with valid admin credentials to achieve root-level privi

Microsoft on Wednesday detailed a previously undiscovered technique put to use by the TrickBot malware that involves using compromised Internet of Things (IoT) devices as a go-between for establishing communications with the command-and-control (C2) servers. "By using MikroTik routers as proxy servers for its C2 servers and redirecting the traffic through non-standard ports, TrickBot adds another persistence layer that helps malicious IPs evade detection by standard security systems," Microsoft's Defender for IoT Research Team and Threat Intelligence Center (MSTIC)  said . TrickBot, which emerged as a banking trojan in 2016, has evolved into a sophisticated and persistent threat, with its modular architecture enabling it to adapt its tactics to suit different networks, environments, and devices as well as offer access-as-a-service for next-stage payloads like Conti ransomware. The expansion to TrickBot's capabilities comes amid reports of its  infrastructure goin

Cisco has patched multiple critical  security vulnerabilities  impacting its RV Series routers that could be weaponized to elevate privileges and execute arbitrary code on affected systems, while also warning of the existence of proof-of-concept (PoC) exploit code targeting some of these bugs. Three of the 15 flaws, tracked as CVE-2022-20699, CVE-2022-20700, and CVE-2022-20707, carry the highest CVSS rating of 10.0, and affect its Small Business RV160, RV260, RV340, and RV345 Series routers. Additionally, the flaws could be exploited to bypass authentication and authorization protections, retrieve and run unsigned software, and even cause denial-of-service (DoS) conditions. The networking equipment maker acknowledged that it's "aware that proof-of-concept exploit code is available for several of the vulnerabilities" but didn't share any further specifics on the nature of the exploit or the identity of the threat actors that may be exploiting them. CVE-2022-20699

Networking equipment company Netgear has released patches to remediate a high-severity remote code execution vulnerability affecting multiple routers that could be exploited by remote attackers to take control of an affected system. Traced as  CVE-2021-40847  (CVSS score: 8.1), the security weakness impacts the following models - R6400v2 (fixed in firmware version 1.0.4.120) R6700 (fixed in firmware version 1.0.2.26) R6700v3 (fixed in firmware version 1.0.4.120) R6900 (fixed in firmware version 1.0.2.26) R6900P (fixed in firmware version 3.3.142_HOTFIX) R7000 (fixed in firmware version 1.0.11.128) R7000P (fixed in firmware version 1.3.3.142_HOTFIX) R7850 (fixed in firmware version 1.0.5.76) R7900 (fixed in firmware version 1.0.4.46) R8000 (fixed in firmware version 1.0.4.76) RS400 (fixed in firmware version 1.5.1.80) According to GRIMM security researcher Adam Nichols, the vulnerability resides within Circle , a third-party component included in the firmware that offer

A critical vulnerability in Cisco Small Business Routers will not be patched by the networking equipment giant, since the devices reached end-of-life in 2019. Tracked as CVE-2021-34730 (CVSS score: 9.8), the issue resides in the routers' Universal Plug-and-Play (UPnP) service, enabling an unauthenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability, which the company said is due to improper validation of incoming UPnP traffic, could be abused to send a specially-crafted UPnP request to an affected device, resulting in remote code execution as the root user on the underlying operating system. "Cisco has not released and will not release software updates to address the vulnerability," the company  noted  in an advisory published Wednesday. "The Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers have  entered the end-of-life process .

Unidentified threat actors are actively exploiting a critical authentication bypass vulnerability to hijack home routers as part of an effort to co-opt them to a Mirai-variant botnet used for carrying out DDoS attacks, merely two days after its public disclosure. Tracked as  CVE-2021-20090  (CVSS score: 9.9), the  weakness  concerns a  path traversal vulnerability  in the web interfaces of  routers with Arcadyan firmware  that could allow unauthenticated remote attackers to bypass authentication. Disclosed by Tenable on August 3, the issue is believed to have existed for at least 10 years, affecting at least 20 models across 17 different vendors, including Asus, Beeline, British Telecom, Buffalo, Deutsche Telekom, Orange, Telstra, Telus, Verizon, and Vodafone. Successful exploitation of the vulnerability could enable an attacker to circumvent authentication barriers and potentially gain access to sensitive information, including valid request tokens, which could be used to make re

Cybersecurity researchers have detailed critical security vulnerabilities affecting  NETGEAR DGN2200v1 series routers , which they say could be reliably abused as a jumping-off point to compromise a network's security and gain unfettered access. The three  HTTPd  authentication security weaknesses (CVSS scores: 7.1 – 9.4) impact routers running firmware versions prior to v1.0.0.60, and have since been  fixed by the company  in December 2020 as part of a coordinated vulnerability disclosure process. "The rising number of firmware attacks and ransomware attacks via VPN devices and other internet-facing systems are examples of attacks initiated outside and below the operating system layer," Microsoft 365 Defender Research Team's Jonathan Bar Or  said . "As these types of attacks become more common, users must look to secure even the single-purpose software that run their hardware—like routers." In a nutshell, the flaws allow accessing router management pa

Some widely sold D-Link VPN router models have been found vulnerable to three new high-risk security vulnerabilities, leaving millions of home and business networks open to cyberattacks—even if they are secured with a strong password. Discovered by researchers at Digital Defense, the three security shortcomings were responsibly disclosed to D-Link on August 11, which, if exploited, could allow remote attackers to execute arbitrary commands on vulnerable networking devices via specially-crafted requests and even launch denial-of-service attacks. D-Link DSR-150, DSR-250, DSR-500, and DSR-1000AC and other VPN router models in the DSR Family running firmware version 3.14 and 3.17 are vulnerable to the remotely exploitable root command injection flaw. The Taiwanese networking equipment maker  confirmed  the issues in an advisory on December 1, adding that the patches were under development for two of three flaws, which have now been released to the public at the time of writing.

The federal prosecutors in the United States have charged Uber's former chief security officer, Joe Sullivan , for covering up a massive data breach that the ride-hailing company suffered in 2016. According to the press release published by the U.S. Department of Justice, Sullivan "took deliberate steps to conceal, deflect, and mislead the Federal Trade Commission about the breach" that also involved paying hackers $100,000 ransom to keep the incident secret. "A criminal complaint was filed today in federal court charging Joseph Sullivan with obstruction of justice and misprision of a felony in connection with the attempted cover-up of the 2016 hack of Uber Technologies," it says. The 2016 Uber's data breach exposed names, email addresses, phone numbers of 57 million Uber riders and drivers, and driver license numbers of around 600,000 drivers. The company revealed this information to the public almost a year later in 2017, immediately after Su

A cybersecurity researcher today disclosed technical details and proof-of-concept of a critical remote code execution vulnerability affecting OpenWrt , a widely used Linux-based operating system for routers, residential gateways, and other embedded devices that route network traffic. Tracked as CVE-2020-7982 , the vulnerability resides in the OPKG package manager of OpenWrt that exists in the way it performs integrity checking of downloaded packages using the SHA-256 checksums embedded in the signed repository index. While an 'opkg install' command is invoked on the victim system, the flaw could allow a remote man-in-the-middle attacker in a position to intercept the communication of a targeted device to execute arbitrary code by tricking the system into installing a malicious package or software update without verification. If exploited successfully, a remote attacker could gain complete control over the targeted OpenWrt network device, and subsequently, over the netwo

Taiwanese networking equipment manufacturer D-Link has agreed to implement a "comprehensive software security program" in order to settle a Federal Trade Commission (FTC) lawsuit alleging that the company didn't take adequate steps to protect its consumers from hackers. Your wireless router is the first line of defense against potential threats on the Internet. However, sadly, most widely-used routers fail to offer necessary security features and have often found vulnerable to serious security flaws, eventually enabling remote attackers to unauthorizedly access networks and compromise the security of other devices connected to it. In recent years, the security of wireless networks has been more of a hot topic due to cyber attacks, as well as has gained headlines after the discovery of critical vulnerabilities—such as authentication bypass , remote code execution , hard-coded login credentials , and information disclosure—in routers manufactured by various brands.

A cybersecurity researcher at Tenable has discovered multiple security vulnerabilities in Verizon Fios Quantum Gateway Wi-Fi routers that could allow remote attackers to take complete control over the affected routers, exposing every other device connected to it. Currently used by millions of consumers in the United States, Verizon Fios Quantum Gateway Wi-Fi routers have been found vulnerable to three security vulnerabilities, identified as CVE-2019-3914, CVE-2019-3915, and CVE-2019-3916. The flaws in question are authenticated command injection (with root privileges), login replay , and password salt disclosure vulnerabilities in the Verizon Fios Quantum Gateway router (G1100), according to technical details Chris Lyne, a senior research engineer at Tenable, shared with The Hacker News. Authenticated Command Injection Flaw (CVE-2019-3914) When reviewing the log file on his router, Chris noticed that the "Access Control" rules in the Firewall settings, availabl

Is your router collects data on your network? Netgear last week pushed out a firmware update for its wireless router model NightHawk R7000 with a remote data collection feature that collects router's analytics data and sends it to the company's server. For now, the company has rolled out the firmware update for its NightHawk R7000, but probably other router models would receive the update in upcoming days. The Netgear's alleged router analytics data collects information regarding: Total number of devices connected to the router IP address MAC addresses Serial number Router's running status Types of connections LAN/WAN status Wi-Fi bands and channels Technical details about the use and functioning of the router and the WiFi network. The company said it is collecting the data for routine diagnostic to know how its products are used and how its routers behave. "Technical data about the functioning and use of our routers and their WiFi network
