Vulnerability Title
Unauthenticated Remote Code Execution via Shell Injection in Web Management Interface
Source: CVE Program / CVE List V5
Vulnerability Description
The web-based management interface uses a modified uhttpd server with CGI shell scripts. The HTTP Basic Authentication username, taken directly from the Authorization header without sanitization, is inserted into a shell command string executed via the system() function. By submitting a specially crafted username containing shell metacharacters, an unauthenticated attacker with network access to the device can escape the command context and execute arbitrary commands with root privileges.
