Blackboard Learning System ComposeMessage.JSP Multiple HTML Injection Vulnerabilities

Blackboard Learning System ComposeMessage.JSP Multiple HTML Injection Vulnerabilities

Blackboard Learning System is prone to multiple HTML-injection vulnerabilities because the software fails to properly sanitize user-supplied input before using it in dynamically generated content.

Attacker-supplied HTML and script code would execute in the context of the affected website, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user; other attacks are also possible.

These versions are vulnerable:

Blackboard Learning System 6.3.1.593
Blackboard Learning and Community Portal System 6.3.1.593

Other versions may also be affected.
