The Tenda W15E router firmware version 15.11.0.10 contains a buffer overflow vulnerability in the hostname parameter of the formSetNetCheckTools function. This vulnerability allows an attacker to trigger a Denial of Service by sending a specially crafted HTTP request that overflows the buffer, disrupting normal device operation. No CVSS score or detailed exploit information is currently available, and no patch or remediation guidance has been provided by the vendor or authoritative sources.

Successful exploitation results in a Denial of Service condition, potentially causing the affected device to crash or become unresponsive. There is no information indicating remote code execution or data compromise. No known exploits are reported in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the device's management interface to trusted networks and monitor for unusual HTTP requests targeting the hostname parameter in formSetNetCheckTools. Avoid exposing the device management interface to untrusted networks.
