Arbitrary file read via sub_177E0 path traversal
Published Apr 10, 2022 · Updated Aug 3, 2024
Path traversal in InHand Networks InRouter 900 before 1.0.0.r11700 allows remote attackers to read arbitrary files. The sub_177E0 function accepts a caller-controlled path and reads files outside the intended directory without proper pathname restriction. The CVSS record indicates that no authentication or user interaction is required over the network, exposing confidential router data without changing integrity or availability.
