CVE-2026-113389 Details
Description
A vulnerability was detected in DrayTek Vigor2960 1.5.1.6 Revision 8218. Affected by this vulnerability is the function set_table of the file /cgi-bin/mainfunction.cgi of the component CGI Process. The manipulation of the argument sectiontype results in command injection. The attack may be launched remotely. The exploit is now public and may be used. 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.
A command injection vulnerability has been identified in the DrayTek Vigor2960 router, specifically in the 1.5.1.6 Revision 8218 firmware. The issue arises in the CGI process, within the 'set_table' function of the 'mainfunction.cgi' file. An authenticated attacker can exploit this vulnerability by manipulating the 'sectiontype' argument, leading to arbitrary command execution on the device. The vulnerability is present in a product that is no longer supported by the vendor.
Users are advised to update to DrayTek Vigor2960 firmware version 1.5.1.7, which addresses this vulnerability. For future UCI command constructions, it is recommended to use the UCI library directly or execute a fixed program with an argument array that bypasses shell parsing, avoiding the use of the command injection vulnerability.
