CVE-2023-44012Public exploitNetwork attack vector

Remote script execution via helpkey XSS

Published Oct 2, 2023 · Updated Sep 23, 2024

Cross-site scripting in mojoPortal 2.7.0.0 allows remote attackers to execute arbitrary script in a victim browser via a crafted helpkey parameter. Help.aspx reflects the helpkey value into generated web content without neutralizing script characters, allowing injected markup or code to run in the page context. Exploitation is unauthenticated but requires user interaction, and the demonstrated impact is browser-side data disclosure and page modification rather than service interruption.
