BlackboardCVEs & Vulnerabilities

Blackboard Learn 1.10.1 allows remote authenticated users to read unintended files by entering student credentials and then directly visiting a certain webapps/bbcms/execute/ URL. Note: The vendor disputes this stating this cannot be reproduced.

Blackboard Learn through 9.1 allows XSS by an authenticated user via the Feedback to Learner form.

Blackboard Learn through 9.1 allows XSS by an authenticated user via the Assignment Instructions HTML editor.

Blackboard Collaborate Ultra 20.02 is affected by a cross-site scripting (XSS) vulnerability. The XSS payload will execute on the class room, which leads to stealing cookies from users who join the class. NOTE: Third-parties dispute the validity of this entry as a possible false positive during research

Stored Cross-site scripting (XSS) vulnerability in Blackboard Learn/PeopleTool v9.1 allows users to inject arbitrary web script via the Tile widget in the People Tool profile editor.

The bb-auth-provider-cas authentication module within Blackboard Learn 2018-07-02 is susceptible to HTTP host header spoofing during Central Authentication Service (CAS) service ticket validation, enabling a phishing attack from the CAS server login page.

Blackboard Learn (Since at least 17th of October 2017) has allowed Unvalidated Redirects on any signed-in user through its endpoints for handling Shibboleth logins, as demonstrated by a webapps/bb-auth-provider-shibboleth-BBLEARN/execute/shibbolethLogin?returnUrl= URI.

Cross-site scripting (XSS) vulnerability in Blackboard Vista/CE 8.0 SP6 and earlier allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The automated-backup functionality in Blackboard Transact Suite (formerly Blackboard Commerce Suite) stores the (1) database username and (2) database password in cleartext in (a) script and (b) batch (.bat) files, which allows local users to obtain sensitive information by reading a file.

BbtsConnection_Edit.exe in Blackboard Transact Suite (formerly Blackboard Commerce Suite) before 3.6.0.2 relies on field names when determining whether it is appropriate to decrypt a connection.xml field value, which allows local users to discover the database password via a modified connection.xml file that contains an encrypted password in the <Server> field.

Multiple cross-site request forgery (CSRF) vulnerabilities in Blackboard Academic Suite 8.0.260.7 allow remote attackers to hijack the authentication of student users for requests that change configuration and enrollments via unspecified input to (1) update_module.jsp, (2) enroll_course.pl, and (3) unenroll.jsp.

The server in Blackboard Academic Suite 7.x stores MD5 password hashes that are provided directly by clients, which makes it easier for remote attackers to access accounts via a modified client that skips the javascript/md5.js hash calculation, and instead sends an arbitrary MD5 string.

Multiple cross-site scripting (XSS) vulnerabilities in Blackboard Academic Suite 7.x and earlier, and possibly some 8.0 versions, allow remote attackers to inject arbitrary web script or HTML via (1) the searchText parameter in a Course action to webapps/blackboard/execute/viewCatalog or (2) the data__announcements___pk1_pk2__subject parameter in an ADD action to bin/common/announcement.pl.

Multiple cross-site scripting (XSS) vulnerabilities in messaging/course/composeMessage.jsp in BlackBoard Learning System 6.3.1.593 and earlier in BlackBoard Academic Suite allow remote attackers to inject arbitrary web script or HTML via the (1) subject_t and (2) body_text parameters. NOTE: vector 2 requires bypassing a client-side security mechanism that attempts to block XSS sequences.

Multiple cross-site scripting (XSS) vulnerabilities in Blackboard Learning System 6, Blackboard Learning and Community Portal Suite 6.2.3.23, and Blackboard Vista 4 allow remote attackers to inject arbitrary Javascript, VBScript, or HTML via (1) data, (2) vbscript, and (3) malformed javascript URIs in various HTML tags when posting to the Discussion Board.

Cross-site scripting (XSS) vulnerability in Blackboard Academic Suite 6.2.3.23 allows remote authenticated users to inject arbitrary HTML or web script by bypassing client-side validation through disabling JavaScript when submitting an essay response, which has no server-side validation before being viewed via "View Attempt Details" in the Gradebook.

Blackboard Academic Suite 6.0 and earlier does not properly clear session information when de-authenticating a user who is idle, which allows subsequent users to log in as the previous user and gain privileges. NOTE: the vendor has disputed this issue, saying that "This is a customer specific issue related to their Kerberos authentication single sign-on application and not a vulnerability in the Blackboard product.

The login page in 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 bypass authentication and gain privileges as other users via a modified user_id parameter and a "/" in the encoded_pw parameter.

announcement.pl in 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 gain administrator privileges by setting the context parameter to "admin".

Cross-site scripting (XSS) vulnerability in 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 inject arbitrary web script or HTML via the context parameter to announcement.pl, which is reflected in the resulting page.

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.
