Remote denial of service via formRoute stack overflow
Published Dec 30, 2023 · Updated Nov 20, 2024
Stack overflow in TOTOLINK X2000R Gh firmware 1.0.0-B20230221.0948.web allows remote attackers to disrupt service via formRoute. The formRoute handler processes attacker-controlled route data in a stack buffer without sufficient bounds, triggering stack exhaustion. Network access requires no authentication or user interaction; the record does not publish whether exploitation achieves code execution beyond the documented high-impact compromise potential.
