CVE-2011-3749 in ka-Map
Summary
by MITRE
ka-Map 1.0-20070205 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by test.php and certain other files.

The vulnerability identified as CVE-2011-3749 affects ka-Map version 1.0-20070205, a web mapping application that provides geospatial data visualization capabilities. This issue represents a classic information disclosure vulnerability where the application fails to properly handle error conditions, resulting in the exposure of sensitive system information. The flaw manifests when remote attackers make direct requests to specific php files within the application, particularly test.php and related components, causing the system to return error messages that contain the complete installation path of the application on the server.
The technical implementation of this vulnerability stems from inadequate error handling mechanisms within the ka-Map application framework. When a user or attacker directly accesses php files that are not properly configured or do not exist, the application generates error messages that inadvertently reveal the absolute file path where the application is installed on the web server. This occurs because the application does not sanitize error outputs or implement proper exception handling that would prevent sensitive path information from being exposed to unauthorized parties. The vulnerability is classified under CWE-200, which specifically addresses information exposure, and represents a fundamental weakness in the application's security posture that violates the principle of least privilege and information hiding.
The operational impact of this vulnerability extends beyond simple path disclosure, as the revealed installation paths can serve as critical intelligence for attackers planning more sophisticated attacks. Knowledge of the exact file structure and installation location enables attackers to craft more targeted exploitation strategies, potentially leading to further information disclosure, directory traversal attacks, or even remote code execution if additional vulnerabilities exist within the application's architecture. This type of information exposure aligns with techniques described in the MITRE ATT&CK framework under the Information Discovery tactic, where adversaries seek to gather information about the system environment to inform their attack strategies. The vulnerability creates a reconnaissance opportunity that significantly reduces the attack surface complexity for threat actors.
Mitigation strategies for CVE-2011-3749 involve implementing proper error handling and input validation within the ka-Map application. System administrators should configure the web server to suppress detailed error messages and implement custom error pages that do not reveal system information. The application should be updated to version 1.0-20070205 or later, as this vulnerability was likely addressed in subsequent releases. Additionally, implementing proper access controls and restricting direct access to php files through web server configuration can prevent unauthorized users from triggering the error conditions that lead to path disclosure. Network segmentation and web application firewalls can also provide additional layers of protection by monitoring and filtering requests that attempt to access sensitive application components directly. The vulnerability demonstrates the importance of secure coding practices and proper error handling as outlined in the OWASP Top Ten security risks, specifically addressing the issue of sensitive data exposure that can compromise entire system security postures.
