CVE-2018-6792 in CVMS HUB
Summary
by MITRE
Multiple SQL injection vulnerabilities in Saifor CVMS HUB 1.3.1 allow an authenticated user to execute arbitrary SQL commands via multiple parameters to the /cvms-hub/privado/seccionesmib/secciones.xhtml resource. The POST parameters are j_idt118, j_idt120, j_idt122, j_idt124, j_idt126, j_idt128, and j_idt130 under formularioGestionarSecciones:tablaSeccionesMib:*:filter. The GET parameter is nombreAgente.

The vulnerability identified as CVE-2018-6792 represents a critical SQL injection flaw within the Saifor CVMS HUB 1.3.1 web application, specifically targeting the /cvms-hub/privado/seccionesmib/secciones.xhtml resource. This vulnerability affects authenticated users who can manipulate multiple POST parameters to execute arbitrary SQL commands, fundamentally compromising the integrity and confidentiality of the underlying database system. The affected parameters include j_idt118, j_idt120, j_idt122, j_idt124, j_idt126, j_idt128, and j_idt130, which are part of the formularioGestionarSecciones:tablaSeccionesMib:*:filter namespace, while the GET parameter nombreAgente also contributes to the attack vector. This vulnerability aligns with CWE-89, which specifically addresses SQL injection weaknesses in software applications, and represents a classic example of insufficient input validation and sanitization in web applications.
The technical exploitation of this vulnerability occurs through the manipulation of HTTP request parameters that are directly incorporated into SQL query construction without proper sanitization or parameterization. When an authenticated user submits malicious input through any of the specified POST parameters or the GET parameter, the application fails to properly escape or validate the input before incorporating it into database queries. This allows attackers to inject malicious SQL fragments that can manipulate the database structure, extract sensitive information, modify or delete data, or potentially escalate privileges within the database environment. The attack surface is particularly concerning because it requires only authenticated access, meaning that users with legitimate credentials can leverage this vulnerability to perform unauthorized database operations.
The operational impact of CVE-2018-6792 extends beyond simple data theft, as it provides attackers with the capability to fundamentally compromise the application's data integrity and availability. Successful exploitation could result in unauthorized access to sensitive information stored within the CVMS HUB system, including potentially confidential operational data, user credentials, or system configuration details. The vulnerability also creates opportunities for attackers to establish persistent access points through database manipulation, potentially allowing for long-term surveillance or data exfiltration. From an enterprise security perspective, this vulnerability undermines the trust model of the application and could lead to regulatory compliance violations if sensitive data is compromised, particularly in environments where data protection regulations such as gdpr or hipaa are applicable.
Organizations affected by this vulnerability should implement immediate mitigations including input validation and parameterized queries to prevent SQL injection attacks. The recommended approach involves implementing proper input sanitization for all parameters used in database queries, particularly those identified in the vulnerability description. Additionally, organizations should consider implementing web application firewalls, database activity monitoring, and regular security assessments to detect and prevent exploitation attempts. The vulnerability demonstrates the importance of following secure coding practices and adheres to ATT&CK technique T1071.005 for application layer attacks, where adversaries exploit application vulnerabilities to execute malicious code. Regular patch management and security awareness training for developers are essential components of a comprehensive defense strategy against such vulnerabilities, as they address both the immediate security gap and prevent similar issues in future development cycles.
