The vulnerability CVE-2019-17119 represents a critical SQL injection flaw in the WiKID 2FA Enterprise Server authentication system affecting versions through 4.2.0-b2053. This issue resides within the Logs.jsp component which processes log data for the two-factor authentication platform. The vulnerability specifically targets authenticated users who can manipulate the source or subString parameters to inject malicious SQL commands into the underlying database queries. This represents a significant security weakness that undermines the integrity of the authentication infrastructure and potentially exposes sensitive user data and system credentials.
The technical implementation of this vulnerability stems from inadequate input validation and parameter sanitization within the Logs.jsp file. When authenticated users submit requests containing malicious payloads through the source or subString parameters, the application fails to properly escape or validate these inputs before incorporating them into SQL queries. This allows attackers to manipulate the database query execution flow and potentially execute arbitrary SQL commands with the privileges of the database user account. The vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws where untrusted data is incorporated into SQL queries without proper sanitization. The attack vector requires authentication, making it a privilege escalation vulnerability that can be exploited by users who already have access to the system.
The operational impact of this vulnerability extends beyond simple data theft and encompasses potential system compromise and unauthorized access to sensitive authentication information. An attacker exploiting this vulnerability could retrieve user credentials, authentication tokens, session information, and other confidential data stored within the WiKID database. The implications are particularly severe for a two-factor authentication system where the compromise of the backend database could lead to widespread authentication bypasses and unauthorized system access. This vulnerability directly impacts the CIA triad by compromising confidentiality and integrity of the authentication system, potentially allowing attackers to manipulate authentication records and gain persistent access to protected resources.
Organizations utilizing WiKID 2FA Enterprise Server should immediately implement mitigations including input validation, parameterized queries, and comprehensive code review processes to address this vulnerability. The recommended remediation involves updating to the latest version of the WiKID software where the vulnerability has been patched, implementing proper input sanitization for all user-supplied parameters, and conducting thorough security testing of web applications. Additionally, organizations should consider implementing database query logging and monitoring to detect potential exploitation attempts. From an ATT&CK framework perspective, this vulnerability maps to T1190 - Exploit Public-Facing Application and T1078 - Valid Accounts, as it leverages authenticated access to exploit application weaknesses and potentially escalate privileges within the authentication system. The vulnerability demonstrates the importance of defense in depth strategies and proper input validation practices in web application security.
