The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The weakness exists due to the parhand parameter handler is responsible for fetching, storing, and changing many of the device’s internal parameters. A remote attacker can set a parameter through the web interface, cause the relevant CGI script (param.cgi) to forward the set-parameter request to the parhand binary, which checks access-rights, and stores the parameter’s value in the relevant configuration file and execute arbitrary shell commands with root privileges.

Successful exploitation of the vulnerability may result in system compromise.
