CVE-2007-6660 in 2z project
Summary
by MITRE
2z project 0.9.6.1 allows remote attackers to obtain sensitive information via (1) a request to index.php with an invalid template or (2) a request to the default URI with certain year and month parameters, which reveals the path in various error messages.

The vulnerability identified as CVE-2007-6660 affects the 2z project version 0.9.6.1, representing a sensitive information disclosure flaw that can be exploited remotely by attackers. This vulnerability manifests through two distinct attack vectors that collectively expose system paths and sensitive operational details to unauthorized parties. The first vector involves sending a malformed request to index.php with an invalid template parameter, while the second vector exploits the default URI with specific year and month parameters that trigger error messages containing path information.
This vulnerability directly relates to CWE-200, which encompasses the disclosure of sensitive information to unauthorized actors. The flaw demonstrates poor error handling practices where the application fails to sanitize error messages before returning them to clients. When invalid template requests are processed, or when specific date parameters are provided, the system generates error responses that inadvertently include file system paths, directory structures, and potentially other sensitive operational details. These error messages serve as a goldmine of information for attackers seeking to understand the underlying system architecture and potentially identify additional attack vectors.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with critical reconnaissance data that can be leveraged for more sophisticated attacks. The exposed paths may reveal directory structures, file locations, and potentially even database connection strings or other sensitive configuration details. This information can significantly aid attackers in planning subsequent exploitation attempts, including potential file inclusion vulnerabilities, directory traversal attacks, or other path-based exploits. The vulnerability essentially provides an attacker with a roadmap of the application's internal structure without requiring additional reconnaissance efforts.
From a threat modeling perspective, this vulnerability aligns with ATT&CK technique T1212, which involves exploitation of software vulnerabilities to gain unauthorized access to systems. The information disclosure aspect of this vulnerability makes it particularly dangerous as it enables attackers to perform more targeted attacks against the application. The remote nature of the exploitation means that attackers can leverage this vulnerability from outside the network perimeter without requiring physical access or prior authentication. Security professionals should consider this vulnerability as part of a broader reconnaissance phase that can lead to more severe compromise scenarios.
Mitigation strategies for this vulnerability should focus on implementing proper error handling and sanitization practices. Applications should be configured to return generic error messages to users while logging detailed technical information internally for administrators. Input validation should be strengthened to prevent malformed requests from triggering error conditions, and all error responses should be sanitized to remove any path information or system-specific details. Additionally, implementing proper access controls and input filtering mechanisms can prevent unauthorized access to sensitive parameters that trigger the vulnerable code paths. Regular security testing and code reviews should be conducted to identify similar error handling issues throughout the application codebase, ensuring that all potential information disclosure vectors are properly addressed.
