The CVE-2011-1667 vulnerability represents a critical sql injection flaw in the Anzeigenmarkt 2011 web application that fundamentally compromises database security. This vulnerability specifically targets the index.php script within the application's directory structure and affects the list action functionality. The flaw manifests when the application fails to properly sanitize user input passed through the q parameter, creating an exploitable pathway for malicious actors to manipulate database queries directly. The vulnerability resides in the application's input validation mechanisms, which do not adequately filter or escape special characters that could alter the intended sql command structure. This weakness aligns with CWE-89, which categorizes sql injection as a persistent and dangerous vulnerability that allows attackers to execute unauthorized database operations.
The technical exploitation of this vulnerability occurs when remote attackers submit malicious input through the q parameter in the list action context. The application processes this input without proper sanitization, allowing sql commands to be appended or modified within the existing query structure. This enables attackers to perform unauthorized database operations including but not limited to data retrieval, modification, deletion, or even administrative actions on the database system. The impact extends beyond simple data theft as attackers can potentially escalate privileges, access sensitive user information, or compromise the entire database infrastructure. The vulnerability operates at the application layer and requires no special privileges to exploit, making it particularly dangerous for web applications that handle sensitive user data or business-critical information.
The operational impact of CVE-2011-1667 can be devastating for organizations utilizing the affected Anzeigenmarkt 2011 platform. Attackers can leverage this vulnerability to extract confidential information from databases, including user credentials, personal data, and business-sensitive records. The vulnerability also enables attackers to modify or delete database content, potentially causing operational disruption and data integrity issues. Depending on the database configuration and the privileges of the database user account, attackers might gain access to administrative functions or even execute operating system commands. This vulnerability directly violates security principles outlined in the mitre attack framework, specifically mapping to techniques involving command injection and credential access. Organizations may face regulatory compliance violations, financial losses, and reputational damage as a result of successful exploitation.
Mitigation strategies for CVE-2011-1667 must address both immediate remediation and long-term security improvements. The primary solution involves implementing proper input validation and parameterized queries to prevent sql injection attacks. Organizations should sanitize all user inputs and utilize prepared statements or stored procedures to separate sql code from data. The application should employ proper escape sequences for special characters and implement whitelisting mechanisms for input validation. Security patches should be applied immediately to update the Anzeigenmarkt 2011 software to versions that address this vulnerability. Additional protective measures include implementing web application firewalls, conducting regular security code reviews, and establishing proper database access controls. Organizations should also monitor database activities for suspicious queries and implement network segmentation to limit the potential impact of successful attacks. These measures align with industry best practices for sql injection prevention and support compliance with security standards such as iso 27001 and nist cybersecurity framework.
