## Affected

- DrayTek Vigor2960: 1.5.1.6 Revision 8218

## Description

A weakness has been identified in DrayTek Vigor2960 1.5.1.6 Revision 8218. The impacted element is the function rename_table of the file /cgi-bin/mainfunction.cgi of the component Rename Table Handler. This manipulation of the argument newtable causes command injection. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 1.5.1.7 is sufficient to resolve this issue. It is suggested to upgrade the affected component. 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.
