Authenticated code execution via unchecked oldfilename copy
Published Jan 2, 2026 · Updated Jan 2, 2026
Buffer overflow in the web-management endpoint of UTT 进取 512W 1.7.7-171114 allows remote authenticated users to execute arbitrary code. The formFtpServerShareDirSelcet handler passes the attacker-controlled oldfilename value to strcpy without checking the destination size. Valid management credentials and network access are required; exploitation can instead crash the web service or router.
