CVE-2006-5109 in CubeCart
Summary
by MITRE
Devellion CubeCart 2.0.x allows remote attackers to obtain sensitive information via a direct request for (1) link_navi.php or (2) spotlight.php, which reveals the path in various error messages. NOTE: the information.php, language.php, list_docs.php, popular_prod.php, sale.php, check_sum.php, and cat_navi.php vectors are already covered by CVE-2005-0607.

The vulnerability identified as CVE-2006-5109 affects Devellion CubeCart 2.0.x e-commerce platforms and represents a sensitive data exposure issue that allows remote attackers to gather system information through direct web requests. This weakness specifically targets two PHP scripts within the application framework namely link_navi.php and spotlight.php which when accessed directly reveal critical system paths in their error messages. The vulnerability falls under the category of information disclosure, where attackers can exploit the application's error handling mechanisms to obtain unauthorized information about the server environment and file structure. This type of vulnerability is particularly concerning as it provides attackers with insights into the underlying system architecture that could be leveraged for further exploitation attempts.
The technical flaw in this vulnerability stems from improper error handling within the CubeCart application's PHP scripts. When link_navi.php or spotlight.php are accessed directly without proper authentication or input validation, the application generates error messages that inadvertently include the full server path where the application is installed. This occurs because the scripts do not properly sanitize their output or implement adequate error handling procedures that would prevent sensitive path information from being exposed to unauthenticated users. The vulnerability demonstrates a lack of proper input validation and error management practices that are fundamental to secure application development. According to CWE standards, this corresponds to CWE-200, which describes information exposure through error messages, and CWE-502, which addresses insecure deserialization that can occur when applications fail to properly handle error conditions.
The operational impact of this vulnerability extends beyond simple information disclosure as it provides attackers with critical reconnaissance data that can significantly aid in subsequent attack phases. The exposed server paths can reveal the exact directory structure, file locations, and potentially even the operating system type being used by the web server. This information can be particularly valuable to attackers planning more sophisticated attacks such as path traversal exploits or local file inclusion vulnerabilities. The vulnerability creates a foothold for attackers to map out the application's architecture and identify potential attack vectors that may not be immediately obvious through normal scanning techniques. From an attacker's perspective, this information can be used to craft more targeted attacks against the application or the underlying server infrastructure, making the initial information disclosure a critical step in the attack lifecycle.
Security practitioners should recognize that this vulnerability aligns with several tactics outlined in the MITRE ATT&CK framework, particularly those related to reconnaissance and initial access phases. The ability to obtain system paths through error messages represents a classic example of information gathering that attackers use to plan more sophisticated attacks. Organizations should implement proper input validation and error handling procedures to prevent such information exposure, ensuring that error messages do not contain sensitive system information. The vulnerability also underscores the importance of secure coding practices and proper application configuration, as the issue could be mitigated through proper error handling implementation. Additionally, network monitoring and intrusion detection systems should be configured to alert on unusual access patterns to PHP scripts that may indicate exploitation attempts. The vulnerability serves as a reminder that even seemingly minor application flaws can provide attackers with significant advantages in the reconnaissance phase of an attack, emphasizing the need for comprehensive security testing and proper error management in all web applications.
