Blackboard Learning and Community Portal System in Academic Suite 6.3.1.424, 6.2.3.23, and other versions before 6 allows remote attackers to list all available categories via a blank category_id parameter to category.pl. NOTE: it is not clear whether this information is sensitive or not, so this might not be an exposure.
Blackboard Learning and Community Portal System in Academic Suite 6.3.1.424, 6.2.3.23, and other versions before 6 allows remote attackers to redirect users to other URLs and conduct phishing attacks via a modified url parameter to frameset.jsp, which loads the URL into a frame and causes it to appear to be part of a valid page.
BlackBoard 1.5.1 allows remote attackers to gain sensitive information via a direct request to (1) checkdb.inc.php, (2) admin.inc.php or (3) cp.inc.php, which reveals the path in a PHP error message.
Cross-site scripting vulnerabilities in Blackboard 5 allow remote attackers to execute arbitrary web script via (1) the course_id parameter in a link to login.pl, (2) the CTID parameter in ProcessInfo.cgi, or (3) the Message parameter in index.cgi.
BlackBoard CourseInfo 4.0 does not properly authenticate users, which allows local users to modify CourseInfo database information and gain privileges by directly calling the supporting CGI programs such as user_update_passwd.pl and user_update_admin.pl.
Blackboard CourseInfo 4.0 stores the local and SQL administrator user names and passwords in cleartext in a registry key whose access control allows users to access the passwords.
