GilaCMS version 1.11.4 contains a critical sql injection vulnerability that affects the core controller component at /src/core/controllers/cm.php. This vulnerability arises from improper input validation and sanitization of the $_GET parameter, which allows attackers to inject malicious sql commands directly into the application's database layer. The flaw exists because the application fails to properly escape or parameterize user-supplied input before incorporating it into sql queries, creating an exploitable path for unauthorized database access and manipulation. This vulnerability falls under the common weakness enumeration CWE-89 which specifically addresses sql injection flaws in software applications.
The technical exploitation of this vulnerability enables attackers to execute arbitrary sql commands against the underlying database through crafted url parameters. An attacker can leverage this weakness to extract sensitive data, modify database records, delete information, or potentially escalate privileges within the application environment. The vulnerability is particularly dangerous because it affects the content management functionality of the cms, which typically requires elevated privileges and can provide access to user accounts, configuration settings, and content management capabilities. The attack surface is broad as the vulnerability affects core cms functionality and can be exploited without requiring authentication.
The operational impact of this vulnerability extends beyond simple data theft to include complete system compromise and potential data breaches. Attackers can use this weakness to gain persistent access to the cms environment, potentially leading to further exploitation of interconnected systems or use of the compromised platform for malicious activities. The vulnerability affects organizations using GilaCMS v1.11.4 and represents a significant risk to data integrity and system security. According to ATT&CK framework, this vulnerability maps to T1190 - exploit public-facing application, and T1071.004 - application layer protocol: dns, as attackers may use this weakness to establish command and control channels or exfiltrate data through database connections.
Mitigation strategies should include immediate patching of the GilaCMS application to the latest version that addresses this vulnerability. Organizations should implement input validation and sanitization measures at the application level, including parameterized queries and prepared statements to prevent sql injection attacks. Network-level protections such as web application firewalls and intrusion detection systems should be configured to monitor for suspicious sql injection patterns. Additionally, regular security audits and penetration testing should be conducted to identify and remediate similar vulnerabilities in other components of the application stack. The vulnerability demonstrates the critical importance of proper input validation and the need for robust database security practices throughout the application lifecycle.
