CVE-2023-40684Network attack vector

Credential disclosure via Daeja viewer script injection

Published Oct 4, 2023 · Updated Sep 19, 2024

Cross-site scripting in IBM Content Navigator 3.0.11, 3.0.13, and 3.0.14 allows remote authenticated users to run JavaScript in the Web UI. The Daeja ViewOne Virtual document viewer accepts user-supplied content that the Web UI executes as arbitrary JavaScript; IBM has not disclosed the exact input field or sanitization failure. Exploitation requires Daeja ViewOne Virtual, low-privileged access, and victim interaction within a trusted session, where the script can alter UI behavior and disclose credentials.
