Arbitrary file deletion via sub_17C08

Published Apr 10, 2022 · Updated Aug 3, 2024

Path traversal in InHand Networks InRouter 900 firmware before 1.0.0.r11700 allows remote attackers to delete arbitrary files. Public disclosure identifies sub_17C08 as vulnerable but does not disclose the request field or the precise pathname-validation operation. The network path requires no authentication or user interaction and exposes file integrity and router availability, with no reported confidentiality impact.
