CVE-2025-4298Network attack vector

Code execution via unbounded funcpara1 formatting

Published May 5, 2025 · Updated May 6, 2025

Buffer overflow in formSetCfm in Tenda AC1206 15.03.06.23 and earlier allows remote authenticated users to execute arbitrary code. The handler passes the funcpara1-derived list name to sprintf without bounding the write to mib_name, overwriting adjacent memory. A crafted request to /goform/setcfm can crash the management process or enable code execution; CNA metrics require low privileges, while NVD assesses no authentication.
