CVE-2020-6850Public exploitNetwork attack vector

Reflected XSS via unsanitized SAML fields

Published Feb 17, 2020 · Updated Aug 4, 2024

Cross-site scripting in miniOrange SAML SP Single Sign-On before 4.8.84 allows remote attackers to execute script via crafted SAML XML at wp-login.php. Utilities.php processes SAMLResponse, RelayState, and the samlp:Response Destination value without sufficient output neutralization before those values reach the login page. Exploitation requires a victim to submit or follow the crafted SAML response in a browser; script execution can alter page content or act with the victim's WordPress session privileges.
