CVE-2026-36777

Name of the Vulnerable Software and Affected Versions Tenda W3 version 1.0.0.3(2204)

Description A stack overflow occurs in the formSetCfm() function when processing the param 1 parameter. This allows an attacker to trigger a Denial of Service (DoS), which is a condition where the device becomes unavailable to its intended users, by sending a specially crafted HTTP request.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, restrict access to the formSetCfm() function to minimize the risk of exploitation.
