CVE-2023-34135Network attack vector

Authenticated arbitrary file read via web service

Published Jul 13, 2023 · Updated Oct 30, 2024

Path traversal in SonicWall GMS 9.3.2-SP1 and earlier and Analytics 2.5.0.4-R7 and earlier allows remote authenticated users to read arbitrary files. A web service method accepts a caller-controlled file path and reads the referenced file without restricting it to an intended directory. The method runs with Tomcat's root privileges, exposing any file readable by that service, including stored administrator password hashes.
