CVE-2023-25825Public exploitNetwork attack vector

Authenticated browser code execution via unescaped log messages

Published Feb 25, 2023 · Updated Mar 10, 2025

Stored XSS in ZoneMinder before 1.36.33 allows remote authenticated users to execute browser code through crafted log entries. The log viewer's processRows function decodes each database-backed Message and inserts it into the page without escaping angle brackets, so a malicious Referer value becomes active markup. Exploitation requires log-viewing access; code runs in that viewer's browser and can read data available to that session, without altering server data.
