CVE-2023-0157Public exploitNetwork attack vector

Stored XSS via unescaped log-file output

Published Apr 10, 2023 · Updated Feb 11, 2025

Stored XSS in TeamUpdraft AIOS before 5.1.5 allows remote authenticated users to execute script in an administrator's browser. The Host system logs view outputs selected log-file contents without escaping, so a one-line JavaScript payload planted in a bogus log file runs when the page opens. Administrator-level access is required to create and select the file, and another administrator must view the page; the script then acts with that viewer's session privileges.
