CVE-2026-5683 Details
Description
A vulnerability was found in Tenda CX12L 16.03.53.12. Affected by this vulnerability is the function fromP2pListFilter of the file /goform/P2pListFilter. Performing a manipulation of the argument page results in stack-based buffer overflow. The attack must originate from the local network. The exploit has been made public and could be used.
A stack-based buffer overflow vulnerability has been identified in the Tenda CX12L router running firmware version 16.03.53.12. The issue arises in the P2pListFilter endpoint, where the fromP2pListFilter function processes the user-controlled page parameter using sprintf. This function writes data into a fixed-size buffer without proper length checks, allowing input larger than 256 bytes to overwrite adjacent memory. Such memory manipulation can lead to application crashes, memory corruption, or arbitrary code execution. The vulnerability poses significant risks to device stability, data confidentiality, and overall system security, requiring immediate attention to prevent exploitation.
