CVE-2026-6134 Details
Description
A security flaw has been discovered in Tenda F451 1.0.0.7_cn_svn7958. This vulnerability affects the function fromqossetting of the file /goform/qossetting. Performing a manipulation of the argument qos results in stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit has been released to the public and may be used for attacks.
A stack-based buffer overflow vulnerability has been identified in the Tenda F451 router, specifically in the firmware version 1.0.0.7_cn_svn7958. The issue arises in the 'fromqossetting' function within the file '/goform/qossetting', where user-supplied data in the 'qos' parameter is improperly handled. The lack of length validation allows for the overflow to occur, potentially leading to a denial-of-service condition or arbitrary code execution. This vulnerability can be exploited remotely, and a public proof-of-concept exploit is available.
