CVE-2026-5154 Details
Description
A vulnerability has been found in Tenda CH22 1.0.0.1/1.If. The impacted element is the function fromSetCfm of the file /goform/setcfm of the component Parameter Handler. The manipulation of the argument funcname leads to stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used.
A stack-based buffer overflow vulnerability has been identified in the Tenda CH22 router, specifically in version 1.0.0.1. The issue arises in the 'fromSetCfm' function within the '/goform/setcfm' file, part of the Parameter Handler component. The vulnerability is triggered by manipulating the 'funcname' and 'funcpara1' parameters. When 'funcpara1' is set to 'save_list_data', the function passes the parameter to 'sub_39798' without proper length validation. This oversight allows for a buffer overflow, which can be exploited remotely, potentially leading to a denial-of-service condition or arbitrary code execution.
