CVE-2023-46177Network attack vector

Authenticated file disclosure via crafted URL traversal

Published Dec 18, 2023 · Updated Aug 2, 2024

Path traversal in IBM MQ Appliance 9.3 LTS and 9.3 CD allows remote authenticated users to read arbitrary system files via crafted URLs. The URL-processing locus does not confine a requested pathname to its intended directory; IBM has not disclosed the affected endpoint, handler, or library. Access to the affected interface and low-privileged credentials are required, and the reported impact is file disclosure without modification or service interruption.
