CVE-2011-3838 in Wuzly
Summary
by MITRE
Multiple SQL injection vulnerabilities in Wuzly 2.0 allow remote attackers to execute arbitrary SQL commands via the (1) u parameter to fp.php, (2) epage parameter to newpage.php, (3) epost parameter to newpost.php, and (4) username parameter to login.php in admin/; or the (5) username parameter to mobile/login.php.

The vulnerability identified as CVE-2011-3838 represents a critical security flaw in the Wuzly 2.0 content management system that exposes multiple pathways for remote SQL injection attacks. This vulnerability falls under the Common Weakness Enumeration category CWE-89, which specifically addresses SQL injection vulnerabilities that occur when user-supplied data is improperly sanitized before being incorporated into SQL queries. The affected application components include several key files within the Wuzly 2.0 framework that process user input without adequate validation or sanitization mechanisms, creating exploitable entry points for malicious actors.
The technical exploitation of this vulnerability occurs through multiple attack vectors that target different PHP scripts within the application's architecture. The primary attack surfaces include the fp.php script where the u parameter is processed, newpage.php with the epage parameter, newpost.php with the epost parameter, and various login scripts in both the main admin directory and mobile interface. These parameters are directly incorporated into database queries without proper input filtering or parameterization, allowing attackers to inject malicious SQL code that can manipulate the underlying database structure. The vulnerability is particularly concerning because it affects both administrative and mobile interfaces, expanding the potential attack surface significantly.
The operational impact of this vulnerability is severe and multifaceted, as successful exploitation could enable attackers to execute arbitrary SQL commands with the privileges of the database user account. This capability allows for complete database compromise including data exfiltration, unauthorized data modification, and potential privilege escalation within the application. Attackers could extract sensitive user information, modify content, create new administrative accounts, or even gain access to the underlying server through database exploitation techniques. The remote nature of the attack means that adversaries do not require physical access to the system or local network presence, making the vulnerability particularly dangerous in publicly accessible environments.
Mitigation strategies for CVE-2011-3838 should focus on implementing proper input validation and parameterized queries throughout the affected application components. The recommended approach involves applying immediate patches or code modifications to sanitize all user-supplied parameters before incorporating them into database queries. Organizations should implement prepared statements or parameterized queries to prevent SQL injection, as outlined in the OWASP Top Ten security guidelines. Additionally, input validation should be strengthened to reject malformed data, and access controls should be reviewed to ensure that only authorized users can access administrative functions. The remediation process should include comprehensive testing to verify that all identified parameters are properly sanitized and that the application no longer accepts malicious SQL payloads through any of the affected entry points. Security monitoring should also be enhanced to detect unusual database access patterns that might indicate exploitation attempts, aligning with the MITRE ATT&CK framework's database access techniques.
