The vulnerability identified as CVE-2007-4602 represents a critical SQL injection flaw within the Micro-CMS content management system version 3.5. This security weakness resides in the cms/revert-content.php script where user input is improperly handled without adequate sanitization or validation. The specific parameter affected is the 'id' parameter which serves as the entry point for malicious SQL commands to be executed within the database layer. This type of vulnerability falls under the Common Weakness Enumeration category CWE-89, which specifically addresses SQL injection vulnerabilities where untrusted data is directly incorporated into SQL command strings without proper escaping or parameterization.
The operational impact of this vulnerability extends far beyond simple data theft, as remote attackers can leverage the SQL injection to execute arbitrary commands on the underlying database server. This capability enables attackers to access, modify, or delete sensitive information stored within the CMS database including user credentials, content management data, and potentially system configuration details. The vulnerability's remote exploitability means that attackers do not require physical access to the system or local network privileges to carry out attacks, making it particularly dangerous in publicly accessible web environments. According to ATT&CK framework category T1190, this vulnerability maps to exploitation of remote services through injection attacks, representing a common vector for initial compromise in many cyber attack chains.
The technical implementation of this flaw demonstrates poor input validation practices where the 'id' parameter from the HTTP request is directly concatenated into SQL query strings without proper parameter binding or input sanitization. This allows attackers to manipulate the SQL execution flow by injecting malicious SQL syntax through the parameter, potentially leading to unauthorized database access. The vulnerability's severity is compounded by the fact that it affects a core content management function, suggesting that successful exploitation could allow attackers to restore or modify content in ways that could compromise the entire website's integrity and potentially provide a foothold for further system compromise. Organizations utilizing this version of Micro-CMS should immediately implement mitigations including input validation, parameterized queries, and access controls to prevent unauthorized database interactions.
Mitigation strategies for CVE-2007-4602 should prioritize immediate patching of the affected Micro-CMS version to the latest available secure release. Additionally, implementing proper input validation and sanitization measures within the application code can prevent malicious SQL fragments from being executed. Network-level protections such as web application firewalls and database access controls should be deployed to limit the potential impact of any successful exploitation attempts. The vulnerability's classification as a remote code execution threat necessitates comprehensive monitoring of database access logs and network traffic for signs of exploitation attempts, as outlined in ATT&CK techniques for command and control operations and credential access. Regular security assessments and penetration testing should be conducted to identify similar injection vulnerabilities within the application stack and ensure that proper security measures are in place to protect against such threats.
