CVE-2022-3245Public exploitNetwork attack vector

Script execution via unsanitized saved tag names

Published Sep 20, 2022 · Updated May 27, 2025

Stored cross-site scripting in Microweber before 1.3.2 allows remote attackers to execute script in a user's browser via a crafted tag name. The getTagButtonHtmlInForm function inserts the saved name directly into a button's HTML without converting it to text or neutralizing markup. Exploitation requires a victim to load the saved tag in the tag-management interface, where injected markup executes with that user's browser privileges.
