CVE-2023-50955

Web server path disclosure via absolute path traversal

Published Feb 21, 2024 · Updated Aug 2, 2024

Absolute path traversal in IBM InfoSphere Information Server 11.7 allows remote authenticated users to disclose the web server installation path. IBM has not published the affected request handler or the operation that exposes the absolute path. A privileged account with adjacent-network access is required, and the disclosed path can support further attacks without directly exposing file contents.
