Technical details
The api.cgi binary's login processing function (sub_12580) constructs a shell command using sprintf() and system() without sanitizing the REMOTE_ADDR environment variable, allowing command injection. An attacker can reach the vulnerable code path via GET /cgi-bin/api.cgi?api=info&client=app without authentication. The vulnerability allows arbitrary OS command execution with web server privileges.
