The CVE-2013-2690 vulnerability represents a critical sql injection flaw in the Synchroweb Technology SynConnect 2.0 web application that exposes the system to remote code execution risks. This vulnerability specifically affects the index.php file and occurs during the logoff action when processing the loginid parameter, creating an attack vector that allows malicious actors to manipulate database queries through crafted input. The flaw stems from insufficient input validation and sanitization mechanisms within the application's authentication handling process, particularly when the system processes user logout requests. The vulnerability is classified under CWE-89 which denotes improper neutralization of special elements used in an sql command, making it a classic sql injection vulnerability that can be exploited across multiple database systems. This weakness enables attackers to bypass authentication mechanisms and potentially gain unauthorized access to sensitive data stored within the application's database backend.
The technical exploitation of this vulnerability requires minimal prerequisites as attackers only need to craft malicious input for the loginid parameter during the logoff action. When the application processes this parameter without proper sanitization, the sql query construction becomes vulnerable to manipulation, allowing attackers to inject malicious sql commands that execute with the privileges of the database user. The operational impact extends beyond simple data theft as successful exploitation can lead to complete database compromise, enabling attackers to read, modify, or delete sensitive information including user credentials, personal data, and system configurations. This vulnerability is particularly dangerous because it operates during the logout process, which may be less monitored than login procedures, and can potentially allow attackers to maintain persistence or escalate privileges within the system. The attack surface is further expanded by the fact that this vulnerability affects the core authentication system, potentially compromising the entire application infrastructure.
Organizations utilizing SynConnect 2.0 should implement immediate mitigations including input validation and parameterized queries to prevent sql injection attacks. The recommended approach involves implementing proper input sanitization techniques that filter or escape special characters in user-supplied data, particularly during authentication and session management processes. According to ATT&CK framework, this vulnerability aligns with T1190 - Exploit Public-Facing Application and T1071.004 - Application Layer Protocol: DNS, as attackers may leverage this weakness to establish persistent access to the system. Additionally, implementing web application firewalls and database activity monitoring solutions can provide additional layers of defense. Security patches should be applied immediately to address the root cause, while organizations should conduct comprehensive vulnerability assessments of their entire application stack to identify similar weaknesses in other components. The remediation process should include code review of all sql query construction methods, implementation of proper error handling to prevent information disclosure, and regular security testing to ensure that similar vulnerabilities are not present in other application modules. Organizations should also consider implementing least privilege database access controls and regular backup procedures to minimize potential damage from successful exploitation attempts.
