Summary
by MITRE
PHP remote file inclusion vulnerability in Clan Manager Pro (CMPRO) 1.1.0 and earlier allows remote attackers to execute arbitrary PHP code via a URL in the (1) rootpath and possibly (2) sitepath parameters to (a) cmpro.ext/comment.core.inc.php and (b) cmpro.intern/comment.core.inc.php.

The vulnerability described in CVE-2006-7045 represents a critical remote file inclusion flaw affecting Clan Manager Pro version 1.1.0 and earlier. This security weakness resides within the application's handling of user-supplied input parameters, specifically targeting the rootpath and sitepath variables that are processed in two distinct core include files. The vulnerability falls under the category of insecure direct object reference and remote code execution, with implications that extend far beyond simple data manipulation. The affected files cmpro.ext/comment.core.inc.php and cmpro.intern/comment.core.inc.php demonstrate a dangerous pattern of accepting external input without proper validation or sanitization, creating an attack surface that allows malicious actors to inject arbitrary PHP code directly into the application's execution flow.
The technical exploitation of this vulnerability occurs when an attacker manipulates the rootpath and sitepath parameters to point to malicious remote URLs containing PHP code. This type of attack directly maps to CWE-88, which describes improper neutralization of special elements used in an expression, and CWE-94, which covers the execution of arbitrary code or commands. The flaw exploits the application's trust in user-provided input, where legitimate parameters are treated as valid paths without proper validation, allowing attackers to inject external content that gets executed within the application context. The vulnerability's impact is amplified by the fact that it affects both external and internal comment core files, suggesting a systemic issue in how the application handles path resolution and file inclusion mechanisms. Attackers can leverage this weakness to execute arbitrary commands on the server, potentially leading to complete system compromise, data exfiltration, or establishment of persistent backdoors.
The operational impact of this vulnerability extends beyond immediate code execution to encompass broader security implications for affected systems. Organizations running Clan Manager Pro versions prior to the fix face significant risk of unauthorized access and data breaches, as the vulnerability allows attackers to bypass traditional security controls and directly manipulate the application's runtime environment. This weakness creates an attack vector that aligns with ATT&CK technique T1059.007 for command and scripting interpreter, enabling adversaries to execute malicious code through PHP interpreter processes. The vulnerability also demonstrates poor input validation practices that violate fundamental security principles, making it particularly dangerous as it can be exploited by attackers with minimal technical expertise. Systems exposed to this vulnerability may experience complete compromise, with attackers able to establish persistent access, escalate privileges, and potentially use the compromised server as a launch point for further attacks against internal networks. The lack of proper sanitization and validation in the parameter handling process creates a persistent threat that remains active until the underlying code is properly patched.
Mitigation strategies for CVE-2006-7045 must address both immediate remediation and long-term architectural improvements. The primary solution involves upgrading to a patched version of Clan Manager Pro that properly validates and sanitizes all user-supplied input parameters before processing. Organizations should implement input validation controls that enforce strict parameter validation, rejecting any input that contains suspicious characters or patterns that could indicate an attempt at remote file inclusion. The application should be configured to disable remote file inclusion functionality entirely and restrict file operations to predefined, trusted paths only. Security measures should include implementing proper access controls, monitoring for unusual file inclusion patterns, and deploying web application firewalls to detect and block malicious requests targeting these parameters. Additionally, developers should adopt secure coding practices that prevent the direct use of user input in file inclusion operations, following principles such as input sanitization, output encoding, and principle of least privilege. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other applications and ensure that the remediation efforts are comprehensive and effective.
