CVE-2007-3328 in Interact
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Interact 2.4 beta 1 allow remote attackers to inject arbitrary web script or HTML via the (1) module_key parameter to (a) kb/kb.php, (b) quiz/runquiz.php, (c) quiz/quiz.php, (d) forum/forum.php, (e) forum/byname.php, and (f) journal/journalview.php in modules/, and unspecified other scripts; the (2) tag_key parameter to modules/journal/journalview.php; the (3) user_group_key parameter to (g) users/secureaccounts.php; and (4) the request_uri parameter to (h) login.php.

The vulnerability identified as CVE-2007-3328 represents a significant cross-site scripting weakness in Interact 2.4 beta 1 content management system that affects multiple core modules and scripts. This vulnerability falls under the Common Weakness Enumeration category CWE-79, which specifically addresses cross-site scripting flaws where untrusted data is improperly incorporated into web pages without proper validation or sanitization. The affected application fails to adequately filter or escape user-supplied input parameters, creating multiple attack vectors that can be exploited by remote attackers to execute malicious scripts in the context of authenticated users' browsers.
The technical flaw manifests through four distinct parameter injection points that collectively create a comprehensive XSS attack surface. The first set of vulnerabilities involves the module_key parameter which can be manipulated in several key files including kb/kb.php, quiz/runquiz.php, quiz/quiz.php, forum/forum.php, forum/byname.php, and journal/journalview.php within the modules directory. These parameters are processed without proper input validation, allowing attackers to inject malicious JavaScript code that executes when other users view the affected pages. The second vulnerability targets the tag_key parameter in modules/journal/journalview.php, while the third involves the user_group_key parameter in users/secureaccounts.php, both of which follow the same pattern of insufficient input sanitization. The fourth vulnerability leverages the request_uri parameter in the login.php file, creating an additional attack vector that can be exploited during authentication processes.
The operational impact of this vulnerability extends beyond simple script injection, as it can enable attackers to perform a wide range of malicious activities including session hijacking, credential theft, data exfiltration, and privilege escalation. When exploited, these vulnerabilities can allow unauthorized users to gain access to sensitive information, manipulate content, or redirect victims to malicious websites. The attack surface is particularly concerning because it affects core application functionality including knowledge base management, quiz systems, forum discussions, journal viewing, and user account management. The vulnerability's presence in login.php also means that attackers could potentially intercept authentication credentials or manipulate the login process itself. According to the MITRE ATT&CK framework, this vulnerability maps to T1059.007 for script injection and T1566 for credential access, representing both execution and reconnaissance capabilities for threat actors.
Mitigation strategies for CVE-2007-3328 require immediate implementation of comprehensive input validation and output encoding measures across all affected parameters. Organizations should implement proper parameter sanitization techniques that filter out or escape potentially dangerous characters including angle brackets, quotes, and script tags. The solution must include context-aware encoding where data is properly escaped based on the output context, such as HTML, JavaScript, or URL contexts. Additionally, implementing a robust Content Security Policy (CSP) header can provide an additional layer of protection by restricting the sources from which scripts can be executed. Regular security audits and input validation testing should be conducted to prevent similar vulnerabilities from emerging in future versions. The affected application should be immediately updated to a patched version that properly validates and sanitizes all user-supplied input parameters, with particular attention to the module_key, tag_key, user_group_key, and request_uri parameters across all vulnerable scripts.
