CVE-2022-34165Network attack vector

Authenticated cache poisoning via improper header validation

Published Sep 9, 2022 · Updated Sep 17, 2024

HTTP header injection in IBM WebSphere Application Server and Liberty allows remote authenticated users to poison caches or inject scripts. IBM has not disclosed the specific web-request header, code locus, or validation error that permits attacker-controlled data to enter downstream HTTP headers. Low-privilege network access is required; affected releases are WebSphere 7.0, 8.0, 8.5, and 9.0 and Liberty 17.0.0.3 through 22.0.0.9.
