CVE-2023-52240Network attack vector

Cross-site scripting via unsanitized SAML URL parameters

Published Dec 29, 2023 · Updated Aug 2, 2024

Cross-site scripting in affected Kantega SSO Enterprise releases before 6.20.0 allows remote attackers to inject scripts into SAML login pages. The SAML POST-binding login servlet renders attacker-controlled URL parameters without adequate sanitization, allowing arbitrary script or HTML content to enter the page. Exploitation requires enabled SAML POST binding and user interaction with a crafted URL; injected scripts execute in the affected page context.
