Sensitive data exposure via persistent Web UI sessions

Published Apr 8, 2020 · Updated Sep 16, 2024

Insufficient session expiration in IBM Security Information Queue 1.0.0 through 1.0.5 allows attackers to read sensitive Web UI data. The Web UI fails to terminate inactive authenticated sessions after its timeout period, leaving established sessions usable. Exploitation requires access to a still-active session and exposes information without reported data modification or service interruption.
