CVE-2022-34316Network attack vector

Information disclosure via unneutralized HTTP header scripting

Published Nov 14, 2022 · Updated Apr 30, 2025

Improper HTTP-header neutralization in IBM CICS TX 11.1 allows remote attackers to disclose information through raw-header processing. The HTTP-header output path leaves web scripting syntax unneutralized or incorrectly neutralized before raw headers reach browser components that can interpret it. Exploitation requires a browser component that processes raw headers, and the published impact is limited to information disclosure without data modification or service interruption.
