VAR-202512-0002

Vulnerability from variot - Updated: 2025-12-19 23:03

A security flaw has been discovered in Tenda CH22 1.0.0.1. This affects the function frmL7ImForm of the file /goform/L7Im. Performing manipulation of the argument page results in buffer overflow. Remote exploitation of the attack is possible. The exploit has been released to the public and may be exploited. The Tenda CH22 is an enterprise-grade wireless router suitable for small and medium-sized businesses or home office environments. It supports a single-band 2.4GHz wireless network with a maximum transmission rate of 450Mbps.

A buffer overflow vulnerability exists in version 1.0.0.1 of the Tenda CH22. This vulnerability is related to the frmL7ImForm function on the /goform/L7Im interface and arises from the lack of valid length validation for the passed page parameter. A remote attacker could exploit this vulnerability to execute arbitrary code, thereby gaining complete control of the device or causing service disruption
