CVE-2007-1897 in WordPress
Summary
by MITRE
SQL injection vulnerability in xmlrpc (xmlrpc.php) in WordPress 2.1.2, and probably earlier, allows remote authenticated users to execute arbitrary SQL commands via a string parameter value in an XML RPC mt.setPostCategories method call, related to the post_id variable.

The vulnerability identified as CVE-2007-1897 represents a critical sql injection flaw within the xmlrpc.php component of WordPress version 2.1.2 and potentially earlier releases. This vulnerability exists within the xmlrpc implementation that handles remote procedure calls, specifically targeting the mt.setPostCategories method which is used for managing post categories through xmlrpc protocols. The flaw occurs when the system processes user-supplied input without proper sanitization, creating an avenue for malicious actors to inject arbitrary sql commands into the underlying database layer.
The technical exploitation of this vulnerability requires an authenticated user account within the wordpress system, making it a privilege escalation issue rather than a purely remote attack vector. Attackers can leverage the post_id variable parameter within the mt.setPostCategories method call to manipulate sql queries executed by the wordpress application. This allows unauthorized execution of sql commands that can potentially lead to complete database compromise, data exfiltration, or unauthorized access to administrative functions. The vulnerability is categorized under CWE-89 which specifically addresses sql injection flaws where untrusted data is incorporated into sql commands without proper validation or sanitization.
The operational impact of this vulnerability extends beyond simple data theft, as it can enable attackers to escalate privileges within the wordpress installation. Once exploited, malicious actors can potentially gain administrative control over the entire blog or website, allowing them to modify content, add new users, or even delete entire databases. The vulnerability affects the core database interaction layer of wordpress, making it particularly dangerous for sites that rely heavily on user-generated content management. Security professionals should note that this vulnerability exists in the xmlrpc.php file which is commonly enabled in wordpress installations, making it a frequent target for automated exploitation tools.
Mitigation strategies for CVE-2007-1897 involve immediate patching of the wordpress installation to version 2.1.3 or later where the vulnerability has been addressed. System administrators should also implement proper input validation and sanitization procedures for all xmlrpc method calls, particularly those involving database operations. Network segmentation and access controls should be enforced to limit the number of authenticated users who can make xmlrpc calls. The vulnerability demonstrates the importance of proper authentication and authorization checks within web applications, as it requires a valid user account to exploit, highlighting the need for robust user management and privilege controls. Organizations should also consider disabling xmlrpc functionality entirely if it is not required for their specific use case, as recommended by the ATT&CK framework for reducing attack surface area. Regular security audits and vulnerability assessments should include checking for enabled xmlrpc endpoints and ensuring proper input handling throughout the application stack.
