Summary

A critical stack-based buffer overflow vulnerability has been identified in the Tenda AC18 router with firmware version 15.03.05.05. This vulnerability arises from improper handling of the 'devName' argument in the formSetDeviceName function within the /goform/SetOnlineDevName file. An attacker can exploit this flaw remotely by crafting specially formed requests, leading to arbitrary code execution or unauthorized access. Notably, despite disclosure to Tenda, there has been no response or patch release, increasing the risk for affected users. Security best practices urge immediate review of device configurations, and affected users should consider disabling remote management features until a fix is implemented.
