CVE-2021-44829Public exploitNetwork attack vector

Client-side script execution via unsanitized ID parameter

Published Jan 20, 2022 · Updated Aug 4, 2024

Cross-site scripting in AFI WebACMS 2.1.0 and earlier allows remote attackers to execute script in a user's browser via a crafted ID parameter. The index.html login form inserts the unsanitized ID query value into its form action attribute, allowing injected markup and JavaScript to enter the response. A victim must open the crafted URL; the resulting script runs in the WebACMS origin and can disclose accessible cookies or alter displayed content.
