The vulnerability CVE-2017-6013 represents a critical SQL injection flaw discovered in Subrion CMS version 4.0.5.10 within the administrative database interface. This vulnerability specifically affects the query parameter handling mechanism that allows remote attackers to execute arbitrary SQL commands against the underlying database system. The flaw exists in the admin/database/ component where user-supplied input is not properly sanitized or escaped before being incorporated into database queries, creating an exploitable pathway for malicious actors to manipulate the database directly.
This SQL injection vulnerability falls under the Common Weakness Enumeration category CWE-89 which specifically addresses improper neutralization of special elements used in SQL commands. The attack vector leverages the administrative interface where legitimate users with access to the database management tools can be tricked into submitting malicious input through the query parameter. The vulnerability is particularly dangerous because it targets administrative components, providing attackers with elevated privileges and direct access to sensitive data stored within the CMS database.
The operational impact of this vulnerability extends beyond simple data theft, as it can enable complete database compromise including unauthorized data modification, deletion, or extraction of sensitive information such as user credentials, personal data, and system configuration details. Attackers could potentially escalate privileges, create backdoor accounts, or even execute arbitrary code on the server hosting the CMS if the database server allows such operations. The vulnerability affects the integrity and confidentiality of the entire content management system, potentially leading to full system compromise and data breaches that could impact thousands of users depending on the scale of the affected installation.
Mitigation strategies should include immediate patching of the Subrion CMS to version 4.0.5.11 or later which contains the necessary fixes for this SQL injection vulnerability. Organizations should implement proper input validation and parameterized queries throughout the application to prevent similar issues in the future. Network segmentation and access controls should be enforced to limit administrative interface access to trusted users only. Additionally, implementing web application firewalls and database activity monitoring can help detect and prevent exploitation attempts. The vulnerability aligns with ATT&CK technique T1071.004 for application layer protocol and T1190 for exploit public-facing application, emphasizing the need for proper input sanitization and access controls in web applications. Regular security audits and penetration testing should be conducted to identify and remediate similar vulnerabilities in the application codebase.
