CVE-2007-6552 in AuraCMS
Summary
by MITRE
Directory traversal vulnerability in index.php in AuraCMS 2.2 allows remote authenticated users to include and execute arbitrary local files via a .. (dot dot) in the act parameter, possibly involving the news pilih component; as demonstrated by including admin/admin_users.php to bypass a protection mechanism against direct request.

The vulnerability identified as CVE-2007-6552 represents a critical directory traversal flaw within AuraCMS 2.2's index.php script that enables authenticated remote attackers to execute arbitrary local file inclusion attacks. This security weakness specifically manifests through the act parameter manipulation, where attackers can exploit the .. (dot dot) sequence to navigate through the file system hierarchy and access restricted files that should normally be protected from direct user access. The vulnerability is particularly concerning because it affects the news pilih component, which serves as a legitimate interface for content management operations but becomes exploitable when manipulated through crafted directory traversal sequences.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the AuraCMS application. When the act parameter contains directory traversal sequences, the application fails to properly validate or sanitize user-supplied input before using it in file inclusion operations. This allows attackers to bypass normal access controls and directly reference files outside of the intended application directory structure. The exploitation process typically involves crafting a malicious request that includes sequences such as ../../../admin/admin_users.php, which enables the attacker to include and execute administrative scripts that would otherwise be protected from direct access by the application's security mechanisms.
From an operational impact perspective, this vulnerability creates significant risks for AuraCMS installations as it allows authenticated users to escalate their privileges and gain access to administrative functions without proper authorization. The ability to include and execute admin/admin_users.php demonstrates how attackers can bypass protection mechanisms designed to prevent direct requests to sensitive administrative files. This exploitation capability can lead to complete system compromise, unauthorized data access, privilege escalation, and potential data corruption or deletion. The vulnerability affects not only the immediate application but can also provide attackers with a foothold for further reconnaissance and lateral movement within the network infrastructure.
Security professionals should address this vulnerability through immediate patching of the affected AuraCMS version, implementing proper input validation mechanisms, and establishing robust file inclusion controls. The mitigation strategy should include implementing proper parameter validation to reject directory traversal sequences, employing secure coding practices that prevent dynamic file inclusion with user-supplied parameters, and maintaining strict access controls for administrative components. Organizations should also consider implementing web application firewalls and intrusion detection systems to monitor for exploitation attempts. This vulnerability aligns with CWE-22 Directory Traversal and follows patterns consistent with ATT&CK technique T1059 Command and Scripting Interpreter, where attackers leverage directory traversal to execute malicious code through file inclusion mechanisms. The remediation process should involve comprehensive security testing and code review to ensure no similar vulnerabilities exist within the application's file handling logic and parameter processing components.
