CVE-2023-35020Network attack vector

Authenticated file disclosure via dot-dot URL traversal

Published Jan 19, 2024 · Updated Oct 21, 2024

Path traversal in IBM Sterling Control Center 6.3.0 allows remote authenticated users to read arbitrary files through crafted URL requests. The URL request handler fails to neutralize dot-dot sequences before resolving requested filesystem paths. Low-privileged access to the web interface is required; the documented consequence is file disclosure, with no reported service interruption.
