Authenticated service interruption via duplicate Content-Length headers
Published Nov 4, 2024 · Updated Nov 5, 2024
Null pointer dereference in Tenda i22 firmware 1.0.0.3(4687) allows remote authenticated users to interrupt the web service. Duplicate Content-Length headers in a crafted SysToo POST request drive websReadEvent into a branch that passes a null buffer pointer to strlen. Low-privileged network access is required, and successful exploitation causes a segmentation fault without reported data disclosure or modification.
