CVE-2023-31004

Host access via man-in-the-middle interception

Published Feb 3, 2024 · Updated Nov 3, 2025

Channel interception in IBM Security Verify Access Appliance and Docker 10.0.0.0 through 10.0.6.1 allows remote attackers to access the host. IBM has not published the affected protocol, component, or incorrect channel-validation operation. Exploitation requires an unauthenticated, high-complexity position on an adjacent network and grants access beyond the affected service.
