CVE-2026-5152 Details
Description
A vulnerability was detected in Tenda CH22 1.0.0.1. Impacted is the function formCreateFileName of the file /goform/createFileName. Performing a manipulation of the argument fileNameMit results in stack-based buffer overflow. The attack may be initiated remotely. The exploit is now 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 'formCreateFileName' function within the '/goform/createFileName' file. The vulnerability is triggered by manipulating the 'fileNameMit' parameter, which is processed by the 'printf' function without proper length validation. This oversight allows for a buffer overflow, potentially leading to a denial-of-service condition or arbitrary code execution. The vulnerability can be exploited remotely, and a public exploit is available.
