CVE-2007-0810 in GeekLog
Summary
by MITRE
PHP remote file inclusion vulnerability in MVCnPHP/BaseView.php in GeekLog 2 and earlier allows remote attackers to execute arbitrary PHP code via a URL in the glConf[path_libraries] parameter. NOTE: this might be a vulnerability in MVCnPHP rather than a vulnerability in GeekLog.

The vulnerability described in CVE-2007-0810 represents a critical remote file inclusion flaw that exists within the GeekLog content management system version 2 and earlier. This issue is classified as a remote code execution vulnerability that stems from improper input validation in the MVCnPHP framework component. The vulnerability specifically affects the BaseView.php file where the glConf[path_libraries] parameter is processed without adequate sanitization, creating an opportunity for malicious actors to inject arbitrary PHP code through remote file inclusion attacks. This type of vulnerability falls under the CWE-88 category of Improper Neutralization of Argument Delimiters in a Command, though more specifically aligns with CWE-94 which covers "Improper Control of Generation of Code ('Code Injection')" and CWE-20 which addresses "Improper Input Validation." The attack vector is particularly dangerous because it allows remote code execution without requiring authentication, making it a severe threat to web application security.
The technical flaw manifests when the application accepts user-supplied input through the glConf[path_libraries] parameter and directly incorporates it into file inclusion operations without proper validation or sanitization. Attackers can exploit this by crafting malicious URLs that point to remote servers hosting malicious PHP payloads, which are then executed on the target server. The vulnerability demonstrates a classic path traversal and code injection pattern where the application fails to distinguish between legitimate library paths and malicious remote URLs. This weakness enables attackers to execute arbitrary commands on the server, potentially leading to complete system compromise, data exfiltration, or further lateral movement within the network infrastructure. The vulnerability's impact is amplified by the fact that it operates at the framework level, affecting the core application architecture rather than just individual components.
The operational impact of this vulnerability extends beyond simple code execution, as it fundamentally undermines the security posture of any GeekLog installation running vulnerable versions. Organizations using affected systems face risks of data breaches, service disruption, and potential regulatory compliance violations. The vulnerability's exploitation can result in persistent backdoors, unauthorized access to sensitive data, and complete server compromise. From an attacker's perspective, this vulnerability aligns with ATT&CK technique T1190 "Exploit Public-Facing Application" and T1059.007 "Command and Scripting Interpreter: PHP," representing a sophisticated attack path that leverages the application's legitimate file inclusion mechanisms for malicious purposes. The vulnerability also relates to the broader attack pattern of using framework-level weaknesses to achieve system-wide compromise rather than targeting individual application components.
Mitigation strategies for this vulnerability require immediate implementation of several defensive measures to protect affected systems. The primary recommendation involves upgrading to a patched version of GeekLog that addresses this vulnerability in the MVCnPHP framework component. Organizations should implement input validation and sanitization measures that prevent remote URL inclusion in library path parameters, using allowlists for acceptable paths rather than denylists that can be bypassed. Network-level protections such as web application firewalls should be configured to block suspicious URL patterns and remote file inclusion attempts. Additionally, system administrators should conduct thorough security audits to identify any systems that might be vulnerable to similar issues within their infrastructure, as this vulnerability pattern often indicates broader architectural weaknesses. The remediation process should also include implementing proper access controls and monitoring mechanisms to detect potential exploitation attempts, while maintaining detailed logs of file inclusion operations for forensic analysis purposes.
