CVE-2004-0132 in ezContents
Summary
by MITRE
Multiple PHP remote file inclusion vulnerabilities in ezContents 2.0.2 and earlier allow remote attackers to execute arbitrary PHP code from a remote web server, as demonstrated using (1) the GLOBALS[rootdp] parameter to db.php, or (2) the GLOBALS[language_home] parameter to archivednews.php, and a malicious version of lang_admin.php.

The vulnerability described in CVE-2004-0132 represents a critical remote code execution flaw affecting ezContents version 2.0.2 and earlier. This vulnerability falls under the category of remote file inclusion attacks that have been extensively documented in cybersecurity literature and categorized under CWE-88, which specifically addresses improper neutralization of special elements used in an OS command. The flaw manifests when the application fails to properly validate or sanitize user-supplied input parameters that are subsequently used to include files from remote servers. In the context of ezContents, attackers can exploit this vulnerability by manipulating specific global parameters within the application's code structure, particularly the GLOBALS[rootdp] parameter in db.php and the GLOBALS[language_home] parameter in archivednews.php.
The technical exploitation of this vulnerability occurs through a sophisticated attack vector that leverages the application's dynamic file inclusion mechanisms. When the vulnerable parameters are manipulated with malicious input, the application incorporates external PHP files into its execution context without proper validation. This allows attackers to inject arbitrary PHP code that gets executed on the target server, effectively granting them remote code execution capabilities. The attack demonstrates how insecure file inclusion practices can lead to complete system compromise, as the malicious lang_admin.php file can be loaded from a remote server and executed within the context of the web application. This particular vulnerability aligns with ATT&CK technique T1190, which describes the use of remote file inclusion to execute code on remote systems.
The operational impact of this vulnerability extends far beyond simple code execution, as it provides attackers with complete control over the affected web server. Successful exploitation allows threat actors to upload additional malicious files, establish persistent backdoors, escalate privileges, and potentially move laterally within the network infrastructure. The vulnerability affects not just the immediate application but can potentially compromise the entire hosting environment, as the exploited server becomes a potential launch point for further attacks. Organizations running vulnerable versions of ezContents face significant risk of data breaches, system compromise, and potential regulatory violations, particularly in environments where sensitive data is processed or stored.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. The primary recommendation involves updating to a patched version of ezContents that properly validates and sanitizes all user input parameters before using them in file inclusion operations. Additionally, implementing input validation at multiple layers including web application firewalls, server-side validation, and proper parameter sanitization techniques can significantly reduce the risk of exploitation. Organizations should also consider implementing the principle of least privilege for web applications, restricting file inclusion capabilities to only necessary components, and regularly auditing application code for insecure file handling practices. The vulnerability underscores the importance of following secure coding practices as outlined in OWASP Top Ten and other industry security standards, particularly those addressing input validation and file inclusion security controls.
