CVE-2008-1068 in Portail Web Php
Summary
by MITRE
Multiple PHP remote file inclusion vulnerabilities in Portail Web Php 2.5.1.1 and earlier allow remote attackers to execute arbitrary PHP code via a URL in the site_path parameter to (1) Vert/index.php, (2) Noir/index.php, and (3) Bleu/index.php in template/, different vectors than CVE-2008-0645.

The vulnerability identified as CVE-2008-1068 represents a critical remote file inclusion flaw affecting Portail Web Php versions 2.5.1.1 and earlier. This security weakness manifests in three specific files within the template directory: Vert/index.php, Noir/index.php, and Bleu/index.php, all of which accept a site_path parameter that can be manipulated by remote attackers. The vulnerability falls under the category of insecure direct object references and remote code execution, with direct implications for web application security and system integrity.
The technical implementation of this vulnerability stems from improper input validation within the PHP application's template processing mechanism. When the site_path parameter is passed to any of the three affected files, the application fails to properly sanitize or validate the input before incorporating it into file inclusion operations. This allows malicious actors to inject arbitrary URLs that point to external PHP scripts, enabling remote code execution on the affected server. The flaw operates at the application layer and specifically targets the PHP include/require functions, which are commonly used for template management and dynamic content loading. This vulnerability is classified as CWE-98, which describes "Improper Direct Object Reference," and represents a variant of the more general CWE-88, "Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')."
The operational impact of CVE-2008-1068 is severe and multifaceted, potentially allowing attackers to gain complete control over affected systems. Successful exploitation enables remote code execution, which can lead to data breaches, system compromise, and unauthorized access to sensitive information. Attackers can leverage this vulnerability to upload malicious payloads, establish backdoors, or perform further reconnaissance within the network. The vulnerability affects web applications that rely on dynamic template inclusion, making it particularly dangerous for content management systems and web portals that do not properly validate user input. Organizations running affected versions of Portail Web Php face significant risk of unauthorized access and potential system compromise, with the attack surface extending to any user who can influence the site_path parameter.
Mitigation strategies for this vulnerability require immediate action to address the root cause through proper input validation and sanitization. The primary recommendation involves implementing strict input validation on all user-supplied parameters, particularly those used in file inclusion operations. Organizations should disable the use of remote file inclusion in PHP applications by setting the allow_url_fopen directive to off in php.ini configuration files. Additionally, developers must implement proper parameter sanitization using functions like filter_var() with appropriate filters or custom validation routines to prevent malicious URLs from being processed. The implementation of a web application firewall can provide an additional layer of protection by monitoring and blocking suspicious requests containing potentially malicious URLs. Regular security updates and patch management are essential, as this vulnerability has been addressed in later versions of the Portail Web Php application. Organizations should also consider implementing principle of least privilege access controls and monitoring for unusual file inclusion patterns to detect potential exploitation attempts. The vulnerability demonstrates the importance of following secure coding practices and adheres to ATT&CK technique T1190, "Exploit Public-Facing Application," which emphasizes the exploitation of web application vulnerabilities for remote code execution.
