CVE-2007-5364 in Shopping Cart
Summary
by MITRE
** DISPUTED ** Directory traversal vulnerability in payments/ideal_process.php in the iDEAL transaction handler in ViArt Shopping Cart allows remote attackers to have an unknown impact via directory traversal sequences in the filename parameter to the createCertFingerprint function. NOTE: this issue is disputed by CVE because PHP encounters a fatal function-call error on a direct request for payments/ideal_process.php.

The vulnerability identified as CVE-2007-5364 pertains to a directory traversal issue within the iDEAL transaction handler component of ViArt Shopping Cart software. This particular flaw exists in the payments/ideal_process.php file where the createCertFingerprint function processes filename parameters. The directory traversal vulnerability represents a significant security weakness that could potentially allow malicious actors to access files outside the intended directory structure. According to the vulnerability description, attackers could exploit this weakness by crafting specific directory traversal sequences within the filename parameter, which would theoretically enable unauthorized access to sensitive system files or data.
The technical nature of this vulnerability aligns with CWE-22, which describes improper limitation of a pathname to a restricted directory, commonly known as directory traversal or path traversal attacks. Such vulnerabilities occur when applications fail to properly validate or sanitize user-supplied input that contains path information. In this case, the filename parameter in the createCertFingerprint function does not adequately validate or sanitize the input, allowing attackers to manipulate the path traversal sequences to access files beyond the intended scope. The vulnerability's classification as disputed by CVE stems from the fact that PHP itself encounters a fatal function-call error when the file is directly accessed, suggesting that the vulnerability may not be exploitable in its simplest form without additional conditions or bypass mechanisms.
The operational impact of this vulnerability, while potentially limited due to the fatal error mentioned in the CVE description, remains concerning from a security standpoint. Even if direct exploitation is prevented by PHP's fatal error handling, the presence of such a flaw indicates poor input validation practices within the application's codebase. Attackers might still leverage this vulnerability as part of a broader attack chain, potentially combining it with other weaknesses or using it to gather information about the system's file structure. The fact that this vulnerability exists in a payment processing component makes it particularly dangerous as it could potentially lead to unauthorized access to payment-related data or system files containing sensitive information.
The disputed nature of this CVE highlights the complexity of vulnerability assessment and the importance of thorough testing in security evaluation. While the vulnerability appears to be a directory traversal issue, the PHP fatal error suggests that exploitation may require additional conditions or bypass techniques. Security professionals should consider this vulnerability as part of a comprehensive security assessment rather than a standalone issue. The vulnerability demonstrates the importance of proper input validation and sanitization in all application components, particularly those handling sensitive data such as payment transactions. Organizations using ViArt Shopping Cart should review their implementation and ensure proper validation of all user inputs, regardless of whether the specific vulnerability proves exploitable in their environment.
From an ATT&CK framework perspective, this vulnerability could map to techniques involving privilege escalation or defense evasion through information gathering, as attackers might attempt to use directory traversal to discover system information or access unauthorized files. The vulnerability's location within a payment processing component also makes it relevant to techniques related to financial data theft or manipulation. Organizations should implement proper access controls, input validation, and monitoring mechanisms to prevent exploitation attempts. The disputed status of the CVE serves as a reminder that vulnerability assessment requires careful consideration of environmental factors and that even seemingly minor code flaws can potentially compound into more significant security issues when combined with other vulnerabilities or misconfigurations in the system.
