CVE-2006-4064 in YenerTurk Haber Script
Summary
by MITRE
SQL injection vulnerability in default.asp in YenerTurk Haber Script 1.0 and earlier allows remote attackers to execute arbitrary SQL commands via the id parameter. NOTE: it was later reported reported that 2.0 is also affected.

The vulnerability identified as CVE-2006-4064 represents a critical sql injection flaw in the YenerTurk Haber Script version 1.0 and earlier, with subsequent confirmation that version 2.0 remains susceptible to the same attack vector. This vulnerability specifically targets the default.asp component of the web application, where user input is improperly handled within sql query construction processes. The affected parameter named 'id' serves as the primary entry point for malicious actors to inject arbitrary sql commands into the backend database system. The flaw stems from insufficient input validation and sanitization mechanisms that fail to properly escape or encode user-supplied data before incorporating it into sql statement execution contexts. This vulnerability classification aligns with common weakness enumeration CWE-89 which specifically addresses sql injection vulnerabilities where untrusted data is directly concatenated into sql commands without proper sanitization. The attack surface is particularly concerning as it enables remote code execution capabilities, allowing attackers to manipulate database contents, extract sensitive information, modify data integrity, or potentially escalate privileges within the affected system.
The operational impact of this vulnerability extends beyond simple data compromise to encompass complete system subversion when exploited by skilled attackers. Remote attackers can leverage this weakness to execute unauthorized database operations including but not limited to data retrieval, modification, deletion, and potentially database schema enumeration. The vulnerability's remote exploitability means that attackers do not require physical access or local system credentials to initiate malicious activities, making it particularly dangerous in web-facing environments. The affected YenerTurk Haber Script application likely processes user-provided identifiers through sql queries without proper parameterization or input filtering, creating an environment where malicious input can directly influence sql statement structure and execution flow. This type of vulnerability represents a fundamental failure in secure coding practices and demonstrates the critical importance of implementing proper input validation and sql query parameterization techniques. The fact that both version 1.0 and 2.0 remain affected indicates a persistent architectural flaw in the application's data handling mechanisms that was not adequately addressed during the version upgrade process, suggesting potential code reuse or incomplete security remediation efforts.
Mitigation strategies for CVE-2006-4064 must address both immediate remediation requirements and long-term architectural improvements to prevent similar vulnerabilities from emerging in future implementations. The primary recommendation involves implementing proper sql parameterization techniques throughout the application codebase, specifically ensuring that all user-provided input including the 'id' parameter is properly bound to sql queries through parameterized statements rather than string concatenation. Organizations should also implement comprehensive input validation mechanisms that filter or reject suspicious characters and patterns commonly associated with sql injection attempts. The implementation of web application firewalls and intrusion prevention systems can provide additional layers of protection by monitoring for known attack patterns and blocking malicious sql injection attempts. Security hardening measures should include restricting database user privileges to the minimum necessary for application functionality, implementing proper error handling that does not expose database structure information, and conducting thorough code reviews focusing on sql query construction patterns. From an operational perspective, regular security assessments and penetration testing should be conducted to identify and remediate similar vulnerabilities across the entire application stack. The remediation process must also include updating to the latest available secure versions of the YenerTurk Haber Script and implementing proper security patch management processes to ensure that future vulnerabilities are addressed promptly. This vulnerability serves as a prime example of how insufficient attention to secure coding practices can create persistent security weaknesses that remain exploitable across multiple versions of software implementations.
