Authenticated memory corruption via crafted page parameter
Published Apr 20, 2026 · Updated Apr 20, 2026
Buffer overflow in Tenda F451 1.0.0.7_cn_svn7958 httpd allows remote authenticated users to corrupt memory via a crafted page parameter. The fromwebExcptypemanFilter handler at /goform/webExcptypemanFilter accepts page, but the disclosure does not identify the unsafe memory operation or destination buffer. Low-privileged access to the network management interface is required; successful exploitation can compromise confidentiality, integrity, and availability.
