A security vulnerability has been detected in DrayTek Vigor2960 1.5.1.6 Revision 8218. This affects the function ruequest_certificate of the file /cgi-bin/mainfunction.cgi of the component IPsec Handler. Such manipulation of the argument option leads to command injection.

The vendor explains: "2960 1.5.1.7 has corrected many security issues. And 2960 is EoS with limited support, only major issues would be reviewed(e.g. unauthenticated vuln.)". This vulnerability only affects products that are no longer supported by the maintainer.
