CVE-2022-34311

Browser session takeover via insufficiently protected credentials

Published Feb 12, 2024 · Updated May 6, 2025

Session credential exposure in IBM CICS TX Standard and Advanced 11.1 allows physically proximate attackers to access a browser session. IBM identifies insufficiently protected credentials but has not disclosed the credential storage or browser-session operation that exposes them. Physical access to the browser is required; successful exploitation grants the attacker the existing session and its authorized actions.
