The vulnerability identified as CVE-2006-4916 represents a critical sql injection flaw within the Tekman Portal version 1.0, specifically affecting the uye_profil.asp component. This vulnerability resides in the Turkish language portal software that was widely used for content management and user profile handling. The flaw manifests through the improper validation of the uye_id parameter, which is utilized to retrieve user profile information from the database. When an attacker submits malicious input through this parameter, the application fails to properly sanitize or escape the input before incorporating it into sql queries, creating an exploitable condition that allows arbitrary sql command execution.
The technical nature of this vulnerability aligns with common weakness enumeration CWE-89, which categorizes sql injection as a fundamental flaw in application security where untrusted data is directly incorporated into sql command construction without adequate sanitization. The vulnerability operates by bypassing normal input validation mechanisms that should prevent malicious sql code from being executed against the backend database. Attackers can manipulate the uye_id parameter to inject sql payloads that may result in unauthorized data access, data modification, or even complete database compromise. This type of vulnerability is particularly dangerous because it can be exploited remotely without requiring authentication, making it accessible to any attacker with network access to the vulnerable system.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with extensive control over the affected database system. Successful exploitation could enable attackers to extract sensitive user information including personal details, login credentials, and potentially administrative access credentials. The vulnerability also poses risks to data integrity and availability, as attackers could modify or delete user records, corrupt database structures, or even escalate privileges to gain system-level access. The remote execution capability means that attackers do not need physical access to the system or knowledge of internal network structures to exploit this flaw, making it particularly attractive to malicious actors seeking to compromise web applications.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. The primary fix involves implementing proper input validation and parameterized queries to prevent sql injection attacks, ensuring that all user-supplied data is properly escaped or sanitized before database interaction. Organizations should also implement proper access controls and database permissions to limit the impact of potential exploitation. Security best practices recommend adopting the principle of least privilege for database accounts, implementing web application firewalls, and conducting regular security assessments. Additionally, the vulnerability highlights the importance of keeping software updated and following secure coding practices as outlined in industry standards such as owasp top ten and the software security development lifecycle. Regular security training for developers and implementation of automated security testing tools can help prevent similar vulnerabilities from being introduced in future versions of the software.
