Technical details
A command injection vulnerability exists in the /cgi-bin/tools/ajax_cmd endpoint of Panabit PAP-XM320 devices running firmware up to and including v7.7. The issue resides in the CGI component's handling of the 'action=runcmd' parameter, which fails to properly sanitize user input before passing it to a system shell. An authenticated attacker can exploit this to execute arbitrary commands with root-level privileges. While authentication is required, the ability to gain full OS-level access on a core networking appliance poses a significant risk to the integrity and confidentiality of the managed network.
