CVE-2008-3313 in CreaCMS
Summary
by MITRE
Multiple PHP remote file inclusion vulnerabilities in CreaCMS 1.0 allow remote attackers to execute arbitrary PHP code via a URL in the (1) cfg[document_uri] parameter to _administration/edition_article/edition_article.php and the (2) cfg[base_uri_admin] parameter to _administration/fonctions/get_liste_langue.php. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

This vulnerability resides within CreaCMS 1.0, a content management system that suffers from multiple remote file inclusion flaws affecting its administrative components. The vulnerability stems from improper input validation and sanitization of user-supplied parameters that are directly incorporated into file inclusion operations. Attackers can exploit these flaws by manipulating the cfg[document_uri] parameter in the edition_article.php file and the cfg[base_uri_admin] parameter in the get_liste_langue.php file to inject malicious URLs that will be executed by the PHP interpreter.
The technical nature of this vulnerability aligns with CWE-88, which describes improper neutralization of special elements used in an expression, specifically the manipulation of file inclusion parameters. This represents a classic remote code execution vector where user input flows directly into include or require statements without proper sanitization. The attack requires minimal privileges and can be executed from any remote location, making it particularly dangerous for web applications. The vulnerability exists because the application fails to validate or sanitize the URL parameters before using them in file inclusion contexts, allowing attackers to specify arbitrary file paths or URLs that will be processed by the PHP engine.
The operational impact of this vulnerability is severe as it provides remote attackers with the ability to execute arbitrary PHP code on the target server. This could lead to complete system compromise, data exfiltration, privilege escalation, and persistent backdoor installation. Attackers could leverage this vulnerability to deploy web shells, access sensitive database credentials, modify website content, or use the compromised server as a launchpad for further attacks within the network. The vulnerability affects the administrative functionality of the CMS, potentially providing attackers with elevated privileges and access to sensitive administrative features that control the entire website.
Mitigation strategies should focus on implementing strict input validation and sanitization for all user-supplied parameters, particularly those used in file inclusion operations. The recommended approach involves implementing whitelisting mechanisms that only allow predefined, safe values for configuration parameters. Additionally, disabling remote file inclusion in PHP configurations using the allow_url_include directive should be enforced. The application should also implement proper parameter validation that rejects suspicious URL patterns and employs proper input encoding techniques. Security measures should include regular security audits, input validation testing, and ensuring that all CMS components are updated to versions that address these known vulnerabilities. This vulnerability demonstrates the critical importance of secure coding practices and input validation in preventing remote code execution exploits that can lead to complete system compromise.
