Cross Site Scripting vulnerability in Ellucian Banner Student Registration Self-Service (StudentRegistrationSsb) 9.23 and prior (no fixed version available) allows a remote attacker to execute arbitrary code via the mepCode parameter of the /ssb/registration endpoint

Ellucian Banner Self-Service Stored XSS via getFacultyMeetingTimes API

Ellucian Banner Self-Service before the April T2 release (2025-04-23) contains a stored cross-site scripting vulnerability in the course search functionality that allows authenticated Banner ERP users to inject malicious payloads into faculty and course fields by exploiting missing HTML encoding during DOM insertion. An attacker with Banner ERP write access can store malicious JavaScript in fields such as faculty displayName, emailAddress, subjectDescription, or courseTitle; these values are subsequently served unsanitized by the unauthenticated getFacultyMeetingTimes API endpoint, causing arbitrary script execution in the browser of any user who views the affected course's meeting times.

Ellucian Banner Self-Service Reflected XSS via dateConverter

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.

Ellucian Banner 9.17 allows Insecure Direct Object Reference (IDOR) via a modified bannerId to the /StudentSelfService/ssb/studentCard/retrieveData endpoint.

Cross-site scripting (XSS) vulnerability in Ellucian (formerly SunGard) Banner Student 8.5.1.2 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Ellucian (formerly SunGard) Banner Student 8.5.1.2 through 8.7 allow remote attackers to enumerate user accounts via a series of requests.

Ellucian (formerly SunGard) Banner Student 8.5.1.2 through 8.7 allows remote attackers to reset arbitrary passwords via unspecified vectors, aka "Weak Password Reset."

Open redirect vulnerability in Ellucian (formerly SunGard) Banner Student 8.5.1.2 through 8.7 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in an unspecified parameter.

An improper authentication vulnerability can be exploited through a race condition that occurs in Ellucian Banner Web Tailor 8.8.3, 8.8.4, and 8.9 and Banner Enterprise Identity Services 8.3, 8.3.1, 8.3.2, and 8.4, in conjunction with SSO Manager. This vulnerability allows remote attackers to steal a victim's session (and cause a denial of service) by repeatedly requesting the initial Banner Web Tailor main page with the IDMSESSID cookie set to the victim's UDCID, which in the case tested is the institutional ID. During a login attempt by a victim, the attacker can leverage the race condition and will be issued the SESSID that was meant for this victim.
