CVE-2022-28985Public exploitNetwork attack vector

Stored script execution via unvalidated Buzz link

Published May 20, 2022 · Updated Aug 3, 2024

Stored XSS in OrangeHRM 4.10.1 allows remote authenticated users to execute scripts in other users' browsers through a crafted Buzz post. The addNewPost endpoint stores createPost[linkAddress] as a clickable link without rejecting the javascript scheme and publishes it in users' Buzz feeds. Exploitation requires a valid account and a victim to click the stored link, after which the script runs in the victim's OrangeHRM session.
