CVE-2022-38801Network attack vector

Administrator session hijacking via unencoded request reasons

Published Nov 30, 2022 · Updated Apr 24, 2025

Stored XSS in ZKTeco BioTime before 8.5.3 Build 20200816.447 allows remote authenticated users to hijack administrator sessions. The web GUI stores employee-supplied reason text for leave, overtime, or manual-log approval requests and renders it for administrators without output encoding. An employee account and an administrator viewing the request are required; injected JavaScript executes in the administrator's browser and can expose the session cookie or act through that session.
