CVE-2006-6828 in Efkan Forum
Summary
by MITRE
Multiple SQL injection vulnerabilities in Efkan Forum 1.0 and earlier allow remote attackers to execute arbitrary SQL commands via (1) the grup parameter in admin.asp, or the id parameter in (2) default.asp or (3) admin.asp. NOTE: The provenance of this information is unknown; the details are obtained solely from third party information. The default.asp/grup vector is already covered by CVE-2006-6794.

The vulnerability described in CVE-2006-6828 represents a critical SQL injection flaw affecting Efkan Forum version 1.0 and earlier implementations. This vulnerability resides within the forum's administrative and default pages, creating multiple attack vectors that enable remote threat actors to execute unauthorized SQL commands against the underlying database system. The affected parameters include the grup parameter in admin.asp and the id parameter in both default.asp and admin.asp, all of which fail to properly validate or sanitize user input before incorporating it into database queries.
The technical exploitation of this vulnerability occurs through improper input handling mechanisms within the web application's codebase. When users submit data through the vulnerable parameters, the application directly incorporates this input into SQL query strings without adequate sanitization or parameterization. This fundamental flaw allows attackers to inject malicious SQL code that can manipulate the database in unintended ways, potentially leading to complete database compromise, data exfiltration, or unauthorized access to sensitive information. The vulnerability aligns with CWE-89, which specifically addresses SQL injection weaknesses in software applications, and demonstrates the classic pattern of insufficient input validation that has plagued web applications for decades.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to escalate privileges within the forum's administrative interface. Successful exploitation could enable threat actors to modify forum content, delete user accounts, access private messages, or even gain persistent access to the server hosting the forum. The fact that the vulnerability affects both default.asp and admin.asp pages suggests a systemic code quality issue that impacts the entire application's security posture, potentially allowing attackers to move laterally from user-facing pages to administrative functions. This represents a significant risk to forum administrators and their users, as the compromise of one page could lead to complete system takeover.
Mitigation strategies for this vulnerability should prioritize immediate patching of the affected Efkan Forum version, as no reliable workarounds exist for this type of injection flaw. Organizations should implement proper input validation and parameterized queries throughout their web applications to prevent similar issues from occurring in the future. The remediation process should include thorough code review of all database interaction points, implementation of proper escape sequence handling, and deployment of web application firewalls to detect and block malicious SQL injection attempts. This vulnerability also highlights the importance of adhering to secure coding practices and following the ATT&CK framework's guidance on preventing command injection attacks, which specifically addresses the techniques used in this exploit. Regular security assessments and penetration testing should be conducted to identify and remediate similar vulnerabilities before they can be exploited by malicious actors.
