VAR-202506-1303

Vulnerability from variot - Updated: 2025-07-04 23:34

A vulnerability was found in TOTOLINK CA300-PoE 6.2c.884. It has been declared as critical. Affected by this vulnerability is the function setUpgradeFW of the file upgrade.so. The manipulation of the argument FileName leads to os command injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. TOTOLINK of CA300-PoE 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. TOTOLINK CA300-PoE is a wireless access point from China's TOTOLINK Electronics.

The TOTOLINK CA300-PoE upgrade.so file has a command injection vulnerability, which is caused by the parameter FileName of the file upgrade.so failing to properly filter special characters and commands in the constructed command. Attackers can exploit this vulnerability to cause arbitrary command execution
