CVE-2008-6010 in SG Real Estate Portal
Summary
by MITRE
Multiple directory traversal vulnerabilities in SG Real Estate Portal 2.0 allow remote attackers to read arbitrary files via a .. (dot dot) in the (1) mod, (2) page, or (3) lang parameter to index.php; or the (4) action or (5) folder parameter in a security request to admin/index.php.

The vulnerability identified as CVE-2008-6010 represents a critical directory traversal flaw affecting the SG Real Estate Portal version 2.0 software. This security weakness stems from inadequate input validation mechanisms within the application's parameter handling processes, specifically impacting multiple entry points within the web application's architecture. The vulnerability exists in both the frontend index.php script and the backend admin/index.php script, creating multiple attack vectors for malicious actors seeking unauthorized access to sensitive system resources.
The technical exploitation of this vulnerability occurs through the manipulation of specific parameters within HTTP requests sent to the affected web application. Attackers can leverage the .. (dot dot) sequences in parameters such as mod, page, lang, action, and folder to navigate outside the intended directory structure and access arbitrary files on the server filesystem. This occurs because the application fails to properly sanitize or validate user-supplied input before using it to construct file paths, allowing attackers to craft malicious requests that bypass normal access controls and directory restrictions. The vulnerability directly maps to CWE-22, which describes improper limitation of a pathname to a restricted directory, commonly known as path traversal or directory traversal attacks.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with the capability to access sensitive system files, configuration data, and potentially execute arbitrary code depending on the server configuration. Remote attackers can exploit these vulnerabilities without authentication, making the attack surface particularly dangerous as it requires no prior access credentials or privileges. The affected parameters in both index.php and admin/index.php represent critical application entry points that control content delivery and administrative functions, respectively, meaning successful exploitation could lead to complete system compromise and unauthorized access to administrative interfaces.
Security professionals should implement immediate mitigations including input validation and sanitization measures that filter or reject any sequences containing .. characters in the affected parameters. The recommended approach involves implementing strict parameter validation that ensures all user-supplied input conforms to expected patterns and does not contain directory traversal sequences. Additionally, the application should employ proper access controls that restrict file access to only intended directories and implement proper file path resolution that prevents traversal outside designated boundaries. Organizations should also consider implementing web application firewalls and security monitoring solutions to detect and prevent exploitation attempts. The vulnerability aligns with ATT&CK technique T1059 which describes command and scripting interpreter usage, as exploitation may lead to further system compromise and unauthorized access to sensitive data.
