Router crash via PPTP server buffer overflow
Published Nov 21, 2022 · Updated Apr 29, 2025
Out-of-bounds write in Tenda AC15 firmware 15.03.05.18 allows remote attackers to crash the router through its PPTP server handler. The formSetPPTPServer function mishandles attacker-controlled PPTP configuration data and writes beyond a buffer; the specific parameter and copy operation are undisclosed. No authentication or user interaction is required, and the established consequence is service interruption rather than data access or modification.
