CVE-2008-6777 in MyPHP Forum
Summary
by MITRE
Multiple SQL injection vulnerabilities in MyPHP Forum 3.0 and earlier allow remote attackers to execute arbitrary SQL commands via the (1) id parameter in a confirm action, the (2) user parameter in a newconfirm action, and (3) reqpwd action to member.php; and the (4) quote parameter in a post action and (5) pid parameter in an edit action to post.php, different vectors than CVE-2005-0413.2 and CVE-2007-6667.

The vulnerability identified as CVE-2008-6777 represents a critical SQL injection flaw affecting MyPHP Forum version 3.0 and earlier installations. This security weakness manifests across multiple attack vectors within the forum's core functionality, enabling remote attackers to execute arbitrary SQL commands without authentication. The vulnerability stems from inadequate input validation and sanitization practices within the application's database interaction mechanisms, specifically targeting parameters that handle user-supplied data in various forum operations.
Multiple distinct attack vectors have been identified within this vulnerability, each presenting unique exploitation opportunities for malicious actors. The first vector involves the 'id' parameter within the confirm action, while the second targets the 'user' parameter in the newconfirm action. Additional attack surfaces include the 'reqpwd' action within member.php, the 'quote' parameter in post actions, and the 'pid' parameter during edit operations in post.php. These diverse entry points demonstrate the widespread nature of the input validation failures throughout the application's codebase, making the vulnerability particularly dangerous as it provides multiple pathways for exploitation.
The operational impact of CVE-2008-6777 extends far beyond simple data theft, as successful exploitation can result in complete database compromise and potential system takeover. Attackers can manipulate database queries to extract sensitive information including user credentials, personal data, and forum configurations. The vulnerability's classification aligns with CWE-89, which specifically addresses SQL injection flaws where untrusted data is incorporated into SQL commands without proper sanitization. This weakness directly enables unauthorized access to backend databases and can facilitate privilege escalation attacks within the forum environment.
The exploitation of these vulnerabilities follows standard SQL injection attack patterns where malicious input is crafted to alter the intended SQL query execution flow. Attackers can leverage these vectors to perform data manipulation, information disclosure, and potentially gain unauthorized administrative access to the forum system. The presence of multiple attack vectors increases the likelihood of successful exploitation, as defenders must secure all identified parameters rather than focusing on a single point of failure. This vulnerability demonstrates the critical importance of implementing comprehensive input validation and parameterized queries as defensive measures against SQL injection attacks.
Mitigation strategies for CVE-2008-6777 require immediate implementation of proper input sanitization and parameterized query usage throughout the affected application. Organizations should upgrade to MyPHP Forum versions that address these vulnerabilities, while implementing web application firewalls to detect and block malicious SQL injection attempts. The remediation process must include thorough code review to identify all input handling points and ensure proper escaping of special characters in database queries. Additionally, implementing the principle of least privilege for database accounts and regular security audits will help minimize the potential impact of similar vulnerabilities in the future. These measures align with ATT&CK framework techniques targeting credential access and defense evasion, emphasizing the need for comprehensive security controls beyond simple patching approaches.
