CVE-2026-3378 Details
Description
A flaw has been found in Tenda F453 1.0.0.3. This affects the function fromqossetting of the file /goform/qossetting. Executing a manipulation of the argument qos can lead to buffer overflow. The attack can be launched remotely. The exploit has been published and may be used.
A buffer overflow vulnerability has been identified in the Tenda F453 router, specifically in version 1.0.0.3. The issue arises in the 'fromqossetting' function within the '/goform/qossetting' file, where user-provided input in the 'qos' parameter is not properly validated before being copied to a stack-based buffer. This lack of length checking allows for remote exploitation, potentially leading to a denial-of-service condition or arbitrary code execution.
