Unauthenticated router crash via malformed security request

Published Feb 1, 2023 · Updated Aug 2, 2024

Memory corruption in TRENDnet TEW-811DRU 1.0.10.0 httpd allows remote attackers to crash the router via a crafted request. The /wireless/security.asp handler accepts a malformed POST body and corrupts memory, but public records do not identify the faulty memory operation. No authentication or user interaction is required, and the documented consequence is an availability-only service interruption.
