The CVE-2010-5062 vulnerability represents a critical sql injection flaw discovered in the search.php script of MH Products kleinanzeigenmarkt web application. This vulnerability specifically affects the handling of the c parameter which is used for search functionality within the classified advertisements platform. The flaw allows remote attackers to inject malicious sql commands directly into the application's database query execution flow, potentially compromising the entire database infrastructure.
This vulnerability falls under the common weakness enumeration CWE-89 which categorizes sql injection as a serious security flaw that occurs when an application fails to properly sanitize user input before incorporating it into sql queries. The attack vector specifically targets the c parameter in the search.php script where user-supplied data is directly concatenated into database queries without proper input validation or parameterization. The vulnerability exists because the application does not implement proper input sanitization mechanisms or prepared statements that would separate sql command structure from data input.
The operational impact of this vulnerability is severe and multifaceted. Remote attackers can exploit this flaw to execute arbitrary sql commands on the affected database server, potentially leading to complete database compromise, data exfiltration, and unauthorized access to sensitive user information. Attackers may be able to retrieve confidential data including user credentials, personal information, and classified advertisement details. The vulnerability also enables privilege escalation attacks where malicious actors could potentially gain administrative access to the database system. Additionally, this flaw could facilitate data manipulation attacks allowing attackers to modify or delete critical database records, thereby compromising the integrity and availability of the classified advertising platform.
The attack surface for this vulnerability extends beyond simple data theft to include potential system compromise and persistent access. According to the attack technique framework, this represents a direct path for attackers to leverage the sql injection weakness through the web interface, making it particularly dangerous as it requires no special privileges or physical access to the system. Security professionals should note that this vulnerability aligns with the attack pattern of sql injection as documented in the mitre attack framework where adversaries exploit insufficient input validation to execute malicious sql commands. The vulnerability demonstrates the critical importance of implementing proper input validation and parameterized queries as recommended by secure coding practices and industry standards.
Mitigation strategies for CVE-2010-5062 should focus on immediate code-level fixes including the implementation of proper parameterized queries or prepared statements for all database interactions. The application should validate and sanitize all user input, particularly the c parameter in this context, using whitelisting approaches or proper escaping mechanisms. Organizations should implement proper input validation at multiple layers including web application firewalls, database access controls, and application code level protections. Regular security audits and code reviews should be conducted to identify similar vulnerabilities in other application components. The fix should also include proper error handling that does not expose database structure information to end users, as this could aid attackers in crafting more sophisticated attacks. Additionally, implementing database activity monitoring and intrusion detection systems can help identify exploitation attempts and provide early warning of potential security breaches.
