CVE-2017-20008Public exploitNetwork attack vector

Reflected XSS via unsanitized user parameter

Published Nov 29, 2021 · Updated Aug 5, 2024

Reflected XSS in Fullworks Plugins myCred before 1.7.8 lets remote attackers run script in an administrator browser through a crafted user parameter. The Points Log admin dashboard reflects the user parameter without sanitizing or escaping it, allowing injected markup and script to execute when the page is rendered. Exploitation requires an administrator to open the crafted link while viewing Points Log; impact is bounded to script execution in that browser context.
