Vulnerability from variot - Updated: 2025-08-21 23:18

A vulnerability, which was classified as critical, has been found in TOTOLINK N200RE 9.3.5u.6095_B20200916/9.3.5u.6139_B20201216. Affected by this issue is the function sub_41A0F8 of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument Hostname leads to os command injection. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. TOTOLINK of N200RE The firmware contains a command injection vulnerability. OS A command injection vulnerability exists.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The TOTOLINK N200RE is a SOHO wireless router that utilizes 11N wireless technology, achieving a maximum wireless transmission rate of 300Mbps. It supports MIMO architecture and ATCT (Automatic Channel Detection) technology, effectively improving wireless performance and stability.

The TOTOLINK N200RE suffers from a command injection vulnerability caused by the failure of the Hostname parameter in the /cgi-bin/cstecgi.cgi file to properly sanitize special characters and commands in constructed commands. No detailed vulnerability details are currently available
