The vulnerability identified as CVE-2011-4826 represents a critical SQL injection flaw within the AutoSec Tools V-CMS 1.0 content management system. This security weakness resides in the session.php component and specifically affects the process.php script where user input is improperly handled. The vulnerability allows remote attackers to manipulate database queries through the user parameter, potentially enabling full database compromise and unauthorized access to sensitive information. The flaw stems from inadequate input validation and sanitization mechanisms that fail to properly escape or filter user-supplied data before incorporating it into SQL command structures.
The technical implementation of this vulnerability demonstrates a classic SQL injection attack vector where the user parameter in process.php does not employ proper parameterized queries or input sanitization techniques. Attackers can craft malicious SQL payloads that bypass authentication mechanisms and execute arbitrary database commands. This vulnerability falls under CWE-89 which categorizes improper neutralization of special elements used in SQL commands as a primary weakness. The attack surface is particularly concerning as it allows remote exploitation without requiring authentication, making it highly dangerous for web applications that rely on database-backed session management. The vulnerability is further classified under ATT&CK technique T1190 which describes the use of SQL injection to gain unauthorized access to database systems.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete system compromise and potential lateral movement within network infrastructures. An attacker who successfully exploits this vulnerability can extract user credentials, modify database content, and potentially escalate privileges to gain administrative control over the CMS system. The affected V-CMS 1.0 platform likely stores sensitive user information, session data, and potentially configuration details within its database, making it a prime target for malicious actors. Organizations running this vulnerable software face significant risks including data breaches, service disruption, and compliance violations that could result in substantial financial and reputational damage.
Mitigation strategies for CVE-2011-4826 must include immediate implementation of proper input validation and parameterized queries to prevent SQL injection attacks. The recommended approach involves upgrading to a patched version of the V-CMS platform or implementing web application firewalls that can detect and block malicious SQL injection attempts. Security measures should also include disabling unnecessary database user privileges, implementing proper access controls, and conducting regular security assessments to identify similar vulnerabilities. Organizations should also establish robust monitoring systems to detect anomalous database activity that might indicate exploitation attempts. The remediation process should encompass thorough code review to ensure all input handling mechanisms properly sanitize user data and employ proper database abstraction layers that prevent direct SQL command construction from user input. Additionally, implementing database activity monitoring and regular penetration testing can help identify and address similar vulnerabilities before they can be exploited by malicious actors.
