Netgear Routers’ Flaws Expose Users to Malware, Remote Attacks, and Surveillance

As lots of as 5 security flaws have been disclosed in Netgear RAX30 routers that could be chained to bypass authentication and accomplish distant code execution.

“Profitable exploits could allow attackers to keep an eye on users’ internet exercise, hijack internet connections, and redirect site visitors to malicious internet websites or inject malware into network targeted traffic,” Claroty security researcher Uri Katz explained in a report.

Additionally, a network-adjacent risk actor could also weaponize the flaws to obtain and control networked wise devices like security cameras, thermostats, wise locks tamper with router configurations, and even use a compromised network to launch attacks against other units or networks.

The record of flaws, which were shown at the Pwn2Very own hacking competitiveness held at Toronto in December 2022, is as follows –

• CVE-2023-27357 (CVSS score: 6.5) – Missing Authentication Details Disclosure Vulnerability
• CVE-2023-27367 (CVSS score: 8.) – Command Injection Distant Code Execution Vulnerability
• CVE-2023-27368 (CVSS score: 8.8) – Stack-based mostly Buffer Overflow Authentication Bypass Vulnerability
• CVE-2023-27369 (CVSS score: 8.8) – Stack-based mostly Buffer Overflow Authentication Bypass Vulnerability
• CVE-2023-27370 (CVSS score: 5.7) – Product Configuration Cleartext Storage Information Disclosure Vulnerability

A evidence-of-notion (PoC) exploit chain illustrated by the industrial cybersecurity organization shows that it is attainable to string the flaws — CVE-2023-27357, CVE-2023-27369, CVE-2023-27368, CVE-2023-27370, and CVE-2023-27367 (in that get) — to extract the product serial range and in the long run acquire root access to it.

“These 5 CVEs can be chained jointly to compromise afflicted RAX30 routers, the most severe of which allow pre-authentication distant code execution on the system,” Katz famous.

Customers of Netgear RAX30 routers are advised to update to firmware variation 1..10.94 released by the networking firm on April 7, 2023, to tackle the flaws and mitigate probable hazards.
