Detailsinfo

A vulnerability classified as critical was found in Four-Faith F3x24 and F3x36 2.0. Affected by this vulnerability is an unknown part of the file apply.cgi. The manipulation with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The Four-Faith router models F3x24 and F3x36 are affected by an operating system (OS) command injection vulnerability. At least firmware version 2.0 allows authenticated and remote attackers to execute arbitrary OS commands over HTTP when modifying the system time via apply.cgi. Additionally, this firmware version has default credentials which, if not changed, would effectively change this vulnerability into an unauthenticated and remote OS command execution issue.

The advisory is shared at vulncheck.com. This vulnerability is known as CVE-2024-12856 since 12/20/2024. The exploitation appears to be easy. The attack can be launched remotely.
