Title
Command Injection in Router Web Management Interface
Summary
An OS command injection vulnerability exists in the web management interface of Archer C20 v6 firmware when processing certain WAN-related configuration operations. An authenticated administrator may exploit insufficient input validation to execute arbitrary system commands, potentially resulting in full device compromise.
Successful exploitation may allow arbitrary command execution with elevated privileges, compromising the confidentiality, integrity, and availability of the affected device and network traffic passing through it.
Severity
CWE
- CWE-78 - Improper neutralization of special elements used in an OS command ('OS command injection')
