CVE-2007-0861 in phpCOIN
Summary
by MITRE
** DISPUTED ** PHP remote file inclusion vulnerability in modules/mail/index.php in phpCOIN RC-1 and earlier allows remote attackers to execute arbitrary PHP code via a URL in the _CCFG[ _PKG_PATH_MDLS ] parameter. NOTE: this issue has been disputed by a reliable third party, who states that a fatal error occurs before the relevant code is reached.

The vulnerability described in CVE-2007-0861 pertains to a remote file inclusion flaw discovered in the phpCOIN content management system version RC-1 and earlier. This type of vulnerability represents a critical security weakness that can potentially allow attackers to execute arbitrary code on vulnerable systems. The specific file affected is modules/mail/index.php, which serves as a component within the broader phpCOIN framework. The vulnerability manifests through the _CCFG[_PKG_PATH_MDLS] parameter, which is designed to handle module path configurations but fails to properly validate input data.
The technical nature of this flaw aligns with common remote file inclusion vulnerabilities that fall under CWE-88, which describes improper neutralization of special elements used in an input command. This vulnerability operates by accepting user-supplied input through the _CCFG[_PKG_PATH_MDLS] parameter and directly incorporating it into file inclusion operations without adequate sanitization or validation. When an attacker supplies a malicious URL in this parameter, the system attempts to include and execute the remote file, thereby providing an execution path for arbitrary code. This vulnerability type is particularly dangerous because it can enable attackers to upload and execute malicious scripts, potentially leading to complete system compromise.
The operational impact of this vulnerability extends beyond simple code execution to encompass potential data breaches, system takeover, and unauthorized access to sensitive information. Attackers could leverage this flaw to gain shell access to affected systems, deploy backdoors, or manipulate the CMS functionality to serve malicious content. The implications are particularly severe in environments where phpCOIN is used for managing sensitive data or where the system operates with elevated privileges. This vulnerability demonstrates the importance of input validation and proper parameter handling in web applications, as it allows attackers to manipulate the application's behavior through crafted input parameters.
Security professionals should note that while this vulnerability has been disputed by a third party who claims a fatal error prevents exploitation, the potential for remote code execution remains a significant concern. The disputed nature of this vulnerability highlights the complexity of vulnerability assessment and the need for thorough testing and validation. Organizations using phpCOIN RC-1 or earlier versions should consider upgrading to patched versions or implementing additional security controls to mitigate potential risks. The vulnerability also underscores the importance of following secure coding practices such as those outlined in the OWASP Top Ten and the ATT&CK framework, particularly in preventing injection attacks and ensuring proper input validation. The remediation approach should include implementing proper parameter validation, using allowlists for acceptable inputs, and ensuring that all file inclusion operations are properly secured against manipulation by unauthorized users.
