CVE-2020-4934Network attack vector

Authenticated file disclosure via dot-segment traversal

Published Feb 2, 2021 · Updated Sep 16, 2024

Path traversal in IBM Content Navigator 3.0CD allows remote authenticated users to read arbitrary server files via crafted URL requests. Request handling accepts dot-dot path segments without adequately restricting the resolved path to its intended directory. Access requires low-privileged authentication; IBM has not disclosed the affected endpoint or handler, and the reported impact is limited to file reads.
