Unauthenticated service interruption via overlong fn parameter
Published Apr 8, 2026 · Updated Apr 8, 2026
A buffer overflow in tgfile_htm in D-Link DI-8300 16.07.26A1 allows remote attackers to interrupt service via an overlong fn parameter. The function processes the attacker-controlled fn value without rejecting it before the value exceeds its buffer. No authentication or user interaction is required; the documented consequence is service interruption, with no reported data disclosure or modification.
