CVE-2022-42125Network attack vector

Arbitrary file write via unrestricted archive paths

Published Nov 15, 2022 · Updated Jul 9, 2026

Zip Slip in Liferay Portal 7.4.3.5 through 7.4.3.35 and Liferay DXP 7.4 updates 1 through 34 allows attackers to write files. FileUtil.unzip extracts attacker-controlled archive entry paths without restricting the resolved path to the intended extraction directory. Deployment of a malicious plugin or module can create new files or overwrite existing files anywhere permitted by the Liferay process.
