Name of the Vulnerable Software and Affected Versions Totolink A8000RU version 7.1cu.643 b20200521

Description Remote OS command injection is possible via the CGI Handler component. The issue exists in the setTelnetCfg() function within the '/cgi-bin/cstecgi.cgi' endpoint. By manipulating the telnet enabled argument, an attacker can execute arbitrary operating system commands remotely.
