CVE-2022-43971

09.01.2023, 21:15

An arbitrary code exection vulnerability exists in Linksys WUMC710 Wireless-AC Universal Media Connector with firmware <= 1.0.02 (build3). The do_setNTP function within the httpd binary uses unvalidated user input in the construction of a system command. An authenticated attacker with administrator privileges can leverage this vulnerability over the network via a malicious GET or POST request to /setNTP.cgi to execute arbitrary commands on the underlying Linux operating system as root.

Common Weakness Enumeration

CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
The software 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.
