CVE-2006-7102 in phpBurningPortal quiz-modul
Summary
by MITRE
Multiple PHP remote file inclusion vulnerabilities in phpBurningPortal quiz-modul 1.0.1, and possibly earlier, allow remote attackers to execute arbitrary PHP code via a URL in the lang_path parameter to (1) quest_delete.php, (2) quest_edit.php, or (3) quest_news.php.

The vulnerability identified as CVE-2006-7102 represents a critical remote file inclusion flaw within the phpBurningPortal quiz-module version 1.0.1 and potentially earlier versions. This vulnerability falls under the category of insecure direct object references and remote code execution, specifically categorized as CWE-88 and CWE-94 according to the Common Weakness Enumeration framework. The flaw exists due to inadequate input validation and sanitization within the application's handling of user-supplied parameters, particularly the lang_path parameter that is processed through three distinct script files including quest_delete.php, quest_edit.php, and quest_news.php.
The technical implementation of this vulnerability exploits the lack of proper parameter validation in the phpBurningPortal application. When a remote attacker supplies a malicious URL through the lang_path parameter, the application fails to validate or sanitize this input before incorporating it into file inclusion operations. This allows an attacker to manipulate the application's behavior and execute arbitrary PHP code on the target server. The vulnerability specifically affects the application's ability to handle dynamic file paths, where user input is directly concatenated into file inclusion functions without proper security checks, creating an environment where attacker-controlled content can be executed as PHP code.
The operational impact of this vulnerability is severe and far-reaching within the context of web application security. An attacker who successfully exploits this vulnerability can gain complete control over the affected server, potentially leading to data breaches, system compromise, and further lateral movement within the network infrastructure. The vulnerability enables unauthorized execution of code with the privileges of the web server process, which could result in complete system compromise. This type of vulnerability aligns with the ATT&CK technique T1190 - Exploit Public-Facing Application, where adversaries target publicly accessible web applications to gain initial access to target systems.
The exploitation of this vulnerability demonstrates the critical importance of input validation and the principle of least privilege in web application security. The flaw indicates a fundamental lack of proper security measures in the application's codebase, where user input is directly trusted and processed without sanitization. Organizations affected by this vulnerability should immediately implement mitigations including disabling remote file inclusion functionality, implementing proper input validation and sanitization measures, and applying the latest security patches from the vendor. Additionally, security monitoring should be enhanced to detect unusual file inclusion patterns and unauthorized code execution attempts, as this vulnerability represents a classic example of how inadequate input validation can lead to complete system compromise according to established security frameworks and best practices.
