The vulnerability identified as CVE-2007-2067 represents a critical remote file inclusion flaw affecting the WebSlider 0.6 content management system developed by Marco Antonio Islas Cruz. This vulnerability resides in the application's handling of user-supplied input within the path parameter, creating an opportunity for remote attackers to inject and execute arbitrary PHP code on the target server. The flaw manifests across multiple entry points including index.php, modules/pdf.php, plugins/highlight.php, and include/modules.php, indicating a systemic issue in the application's input validation and parameter handling mechanisms.
This vulnerability maps directly to CWE-88, known as "Improper Neutralization of Argument Delimiters in a Command," and more specifically aligns with CWE-94, "Improper Control of Generation of Code ('Code Injection')." The core technical flaw occurs when the application fails to properly sanitize or validate the path parameter before incorporating it into file inclusion operations. When a malicious user supplies a URL in the path parameter, the application processes this input without adequate validation, allowing the attacker to specify arbitrary file paths that can be included and executed on the server. This represents a classic case of insecure direct object reference where user input directly influences file system operations.
The operational impact of this vulnerability is severe and multifaceted. Remote attackers can leverage this weakness to execute arbitrary PHP code, potentially gaining full control over the affected server. This capability enables attackers to perform various malicious activities including but not limited to data exfiltration, server compromise, establishment of backdoors, and further lateral movement within the network. The vulnerability affects the entire WebSlider 0.6 application, making it a prime target for automated exploitation campaigns. The attack surface is particularly concerning because the vulnerable files are commonly accessed entry points within the application's architecture, increasing the likelihood of successful exploitation.
From a threat modeling perspective, this vulnerability aligns with ATT&CK technique T1059.007, "Command and Scripting Interpreter: PHP," as it enables attackers to execute PHP code remotely. The exploitation process typically involves crafting malicious URLs that point to attacker-controlled web servers hosting malicious PHP payloads, which are then included and executed by the vulnerable application. The vulnerability also relates to ATT&CK technique T1505.003, "Server Software Component: Web Shell," as successful exploitation can result in the deployment of persistent web shells on the compromised server. Organizations using WebSlider 0.6 are particularly vulnerable because this flaw allows attackers to bypass traditional security controls and directly compromise server-level operations without requiring additional authentication or privilege escalation.
The recommended mitigations for this vulnerability encompass multiple layers of defense. Immediate patching or upgrading to a version that properly validates and sanitizes input parameters should be prioritized. Implementing input validation that rejects suspicious characters and patterns in the path parameter is essential. The application should employ a whitelist approach for file inclusion operations, allowing only predefined and trusted file paths. Additionally, disabling remote file inclusion capabilities entirely within the PHP configuration using the allow_url_include directive provides an additional protective layer. Network-level controls including firewall rules and web application firewalls can help detect and block malicious requests targeting these specific vulnerable endpoints, though these measures should complement rather than replace proper code-level fixes.
