Lifecycle Timeline
2DescriptionNVD
Ellucian Banner Self-Service before the April T2 release (2025-04-23) contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to execute arbitrary JavaScript in a victim's browser by injecting unsanitized input through the toDateFormat request parameter in the dateConverter endpoint. Attackers can craft a malicious URL targeting the unauthenticated dateConverter endpoint to steal session cookies or perform other malicious actions in the context of the victim's browser session.
AnalysisAI
Reflected XSS in Ellucian Banner Self-Service allows unauthenticated remote attackers to execute arbitrary JavaScript in a victim's browser by injecting unsanitized content via the toDateFormat parameter of the publicly accessible dateConverter endpoint. The CVSS vector (PR:N, S:C) confirms no credentials are needed to craft the attack and that the impact crosses security boundaries into the victim's browser session, enabling session hijacking or credential theft against higher-education users. No public exploit has been identified and this is not listed in CISA KEV, but the unauthenticated endpoint and simple social-engineering delivery path make this practically exploitable with low attacker skill.
