The vulnerability identified as CVE-2008-6475 represents a critical sql injection flaw within the guestbook component of Drake CMS versions 0.4.11 and earlier. This security weakness resides in the file components/guestbook/guestbook.php and specifically targets the handling of the HTTP_VIA header parameter. The vulnerability allows remote attackers to inject malicious sql commands through the Via http header that is passed to index.php, creating a dangerous attack vector that could compromise the entire cms system.
This sql injection vulnerability stems from inadequate input validation and sanitization of user-supplied data within the guestbook component. The application fails to properly escape or filter the HTTP_VIA header value before incorporating it into sql queries, enabling attackers to manipulate the database operations. The attack vector is particularly concerning as it leverages a standard http header that is commonly transmitted in web traffic, making exploitation relatively straightforward for attackers who can craft malicious http requests. The vulnerability is classified under cwe-89 sql injection according to the common weakness enumeration system, which specifically addresses the insertion of malicious sql code into database queries through untrusted input sources.
The operational impact of this vulnerability is severe and multifaceted. Successful exploitation could allow attackers to execute arbitrary sql commands on the database server, potentially leading to complete data compromise including user credentials, personal information, and sensitive content. Attackers could also gain unauthorized access to administrative functions, modify or delete database records, and in some cases escalate privileges to gain full system control. The vulnerability affects all versions of Drake CMS up to and including 0.4.11, making it a widespread concern for organizations running these older versions. The remote nature of the attack means that exploitation can occur from any location without requiring physical access to the system, significantly increasing the attack surface and potential impact.
Mitigation strategies for this vulnerability should prioritize immediate patching of affected Drake CMS installations to version 0.4.12 or later, where the sql injection flaw has been addressed. Organizations should also implement input validation measures to sanitize all http headers before processing, particularly focusing on the HTTP_VIA header which serves as the attack vector. Network level protections such as web application firewalls can provide additional defense in depth by monitoring and filtering suspicious http headers. Security hardening practices including disabling unnecessary http headers, implementing proper access controls, and regular security audits should be implemented. According to the mitre attack framework, this vulnerability would be classified under the execution and privilege escalation tactics, making it a significant concern for threat actors seeking persistent access to web applications. Regular vulnerability assessments and security monitoring should be conducted to identify similar injection flaws in other components of the cms system, as sql injection vulnerabilities often occur in multiple locations within web applications.
