CVE-2007-5304 in ELSEIF CMS
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in ELSEIF CMS Beta 0.6 allow remote attackers to inject arbitrary web script or HTML via the (1) repertimage parameter to utilisateurs/vousetesbannis.php, the (2) elseifvotetxtresultatduvote parameter to utilisateurs/votesresultats.php, and the (3) elseifforumtxtmenugeneraleduforum parameter to moduleajouter/depot/adminforum.php.

The CVE-2007-5304 vulnerability represents a critical cross-site scripting flaw affecting ELSEIF CMS Beta 0.6, demonstrating the persistent security challenges inherent in content management systems during their early development phases. This vulnerability manifests through three distinct attack vectors that exploit insufficient input validation and output encoding mechanisms within the CMS framework. The affected parameters include repertimage in utilisateurs/vousetesbannis.php, elseifvotetxtresultatduvote in utilisateurs/votesresultats.php, and elseifforumtxtmenugeneraleduforum in moduleajouter/depot/adminforum.php, each representing different modules within the CMS architecture that fail to properly sanitize user-supplied data before rendering it in web responses.
The technical exploitation of these vulnerabilities occurs when remote attackers inject malicious script code through the vulnerable parameters, enabling them to execute arbitrary web scripts or HTML content within the context of other users' browsers. This type of attack directly violates the fundamental security principle of input validation and output encoding, as outlined in CWE-79 which specifically addresses cross-site scripting vulnerabilities. The flaw essentially allows attackers to bypass the normal security boundaries that separate user input from executable code, creating a persistent threat that can compromise user sessions, steal sensitive information, or redirect users to malicious websites.
The operational impact of CVE-2007-5304 extends beyond simple data corruption or unauthorized access, as these XSS vulnerabilities can be leveraged for more sophisticated attacks within the broader threat landscape. When combined with other attack techniques, these vulnerabilities can facilitate session hijacking, credential theft, or even serve as a foothold for more advanced persistent threats. The presence of XSS vulnerabilities in CMS components like user management and forum administration modules creates particularly dangerous scenarios where attackers can manipulate core system functionality and potentially gain elevated privileges. This aligns with ATT&CK technique T1566 which describes the use of malicious content to gain initial access or execute malicious code through web applications.
The exploitation of these vulnerabilities demonstrates the critical importance of implementing robust input validation mechanisms throughout the application lifecycle, particularly in CMS environments where user-generated content is common. The affected parameters represent different functional areas of the CMS - user banning functionality, voting systems, and forum administration - each requiring proper sanitization of input data to prevent script injection. Security practitioners should recognize that these vulnerabilities often stem from inadequate security coding practices during development phases, highlighting the necessity of incorporating security considerations early in the software development lifecycle. The remediation approach must include comprehensive output encoding, input validation, and proper parameter handling to prevent similar issues from occurring in future versions of the CMS.
