The vulnerability identified as CVE-2015-0919 represents a critical SQL injection flaw within the administrative backend of the Sefrengo content management system prior to version 1.6.1. This vulnerability exposes the system to remote exploitation by malicious actors who can manipulate database operations through specifically crafted input parameters. The flaw manifests in the backend/main.php script where two distinct parameter names idcat and idclient serve as entry points for unauthorized SQL command execution. The vulnerability falls under the category of CWE-89 SQL Injection as defined by the Common Weakness Enumeration catalog, which classifies this as a persistent and potentially devastating flaw in database interaction logic.
The technical implementation of this vulnerability stems from inadequate input validation and parameter sanitization within the administrative interface. When administrators access the backend system through the main.php script, the application fails to properly escape or validate user-supplied input values passed through the idcat and idclient parameters. This allows attackers to inject malicious SQL syntax directly into the database query execution chain, potentially enabling full database compromise. The remote nature of this vulnerability means that attackers do not require physical access to the system or local network privileges to exploit the flaw, making it particularly dangerous in publicly accessible administrative interfaces.
The operational impact of this vulnerability extends beyond simple data theft or corruption, as successful exploitation can lead to complete system compromise and unauthorized access to sensitive administrative functions. Attackers can leverage this vulnerability to escalate privileges, modify or delete critical system data, and potentially gain persistent access to the administrative backend. The implications are particularly severe for content management systems where administrative interfaces control core system functionality, user management, and content distribution. This vulnerability directly aligns with ATT&CK technique T1190 Exploit Public-Facing Application, as it represents an attack vector through a publicly accessible administrative interface.
Mitigation strategies for CVE-2015-0919 should prioritize immediate patching of the Sefrengo system to version 1.6.1 or later, which contains the necessary input validation and sanitization fixes. Organizations should implement comprehensive input validation at multiple levels including application layer filtering, parameterized queries, and proper escape sequence handling for all database interactions. Network segmentation and access controls should be enforced to limit administrative access to trusted networks only, while monitoring systems should be deployed to detect anomalous database query patterns that may indicate exploitation attempts. Additionally, regular security audits and penetration testing should be conducted to identify similar vulnerabilities in other system components, ensuring comprehensive protection against SQL injection attacks that could compromise system integrity and data confidentiality.
