CVE-2022-34362Network attack vector

Session hijacking via unvalidated Host header

Published Feb 8, 2023 · Updated Mar 24, 2025

HTTP header injection in IBM Sterling Secure Proxy 6.0.3 allows remote authenticated users to cause XSS, cache poisoning, or session hijacking. The request-handling path improperly validates attacker-controlled Host header input; IBM has not identified a narrower file or function. Exploitation requires low privileges and user interaction, and the reported effects are limited to confidentiality and integrity.
