CVE-2007-4068 in Webyapar
Summary
by MITRE
Multiple SQL injection vulnerabilities in Webyapar 2.0 allow remote attackers to execute arbitrary SQL commands via (1) the kat_id parameter to the default URI in a download action or (2) the id parameter to the default URI in a duyurular_detay action.

The vulnerability identified as CVE-2007-4068 represents a critical SQL injection flaw in Webyapar 2.0 content management system that exposes the application to remote code execution attacks. This vulnerability manifests through two distinct attack vectors that exploit improper input validation mechanisms within the web application's database interaction layers. The first vector targets the kat_id parameter during download actions, while the second targets the id parameter during duyurular_detay actions, both occurring at the default URI of the application. These attack paths allow malicious actors to inject arbitrary SQL commands directly into the database query execution pipeline, potentially compromising the entire backend database infrastructure.
The technical exploitation of this vulnerability follows the standard SQL injection attack pattern where unvalidated user input is directly concatenated into SQL queries without proper sanitization or parameterization. When attackers manipulate the kat_id or id parameters with malicious SQL payloads, the application fails to properly escape or validate these inputs before incorporating them into database queries. This lack of input validation creates a direct pathway for attackers to manipulate the intended database operations, potentially allowing them to extract sensitive data, modify database contents, or even execute administrative commands on the underlying database system. The vulnerability specifically aligns with CWE-89 which categorizes SQL injection as a weakness where untrusted data is used to construct SQL queries without proper validation or escaping mechanisms.
The operational impact of this vulnerability extends beyond simple data compromise, as successful exploitation could lead to complete system compromise and unauthorized access to sensitive information stored within the Webyapar 2.0 application. Attackers could potentially gain access to user credentials, personal information, and other confidential data stored in the database. The vulnerability's remote nature means that attackers do not require physical access to the system or local network presence to exploit it, making it particularly dangerous for web applications that are publicly accessible. This type of vulnerability would typically fall under the ATT&CK technique T1190 for exploitation of remote services and T1071.004 for application layer protocol usage, representing a significant security risk for organizations relying on this content management system.
Organizations utilizing Webyapar 2.0 should implement immediate mitigations including input validation and parameterized queries to prevent SQL injection attacks. The most effective remediation involves implementing proper input sanitization techniques and using parameterized database queries that separate SQL command structure from user data. Additionally, implementing proper access controls, database user privilege management, and regular security audits would significantly reduce the risk of exploitation. The vulnerability demonstrates the critical importance of proper input validation and the implementation of secure coding practices as outlined in OWASP Top Ten and other industry security standards. Organizations should also consider implementing web application firewalls and intrusion detection systems to monitor for suspicious SQL injection attempts. Regular security updates and patches should be applied to ensure that known vulnerabilities are addressed promptly, as this particular vulnerability was identified and reported well before the end of 2007, indicating that it should have been remediated in subsequent versions of the software.
