This vulnerability represents a critical sql injection flaw in the nflpick-em.com application affecting versions up to 2.2.x. The issue resides within the _Load_Users function of the LoadUsers.php file located in the html/includes/runtime/admin/JSON/ directory. The vulnerability specifically stems from improper input validation of the sort parameter, which allows attackers to manipulate database queries through malicious input. This weakness enables unauthorized data access and potential database compromise. The vulnerability is classified as remotely exploitable, meaning attackers can leverage this flaw without requiring physical access to the system. The patch identifier dd77a35942f527ea0beef5e0ec62b92e8b93211e provides the specific fix for this issue, addressing the root cause of the sql injection vulnerability. The vulnerability has been assigned the VDB-217270 identifier by the vulnerability database, indicating its recognition within the security community.
The technical exploitation of this vulnerability falls under the CWE-89 category, which specifically addresses sql injection flaws in software applications. This classification indicates that the vulnerability allows attackers to inject malicious sql code through the sort parameter, potentially leading to unauthorized database access, data manipulation, or complete database compromise. The attack vector is particularly concerning because it can be initiated remotely, expanding the potential threat surface significantly. The vulnerability's impact is amplified by the fact that the JSON entrypoint requires administrative privileges, meaning that successful exploitation would likely provide attackers with elevated access rights. This scenario aligns with ATT&CK technique T1078.004, which covers legitimate credentials compromise through administrative access, and T1046, which involves network service scanning that could lead to this type of exploitation.
The operational impact of this vulnerability extends beyond simple data theft, as it represents a fundamental security flaw that could enable complete system compromise. Attackers who successfully exploit this vulnerability could potentially extract sensitive user information, manipulate database records, or even gain deeper system access through database-level attacks. The fact that the JSON endpoint requires admin authentication provides some protection, but once compromised, the attacker would have elevated privileges within the application. This vulnerability demonstrates poor input validation practices and highlights the importance of implementing proper parameter sanitization. The security implications are particularly severe given that this is a web application that likely handles user data, making it a prime target for data exfiltration attacks. Organizations should consider the broader security implications of such vulnerabilities, as they often indicate systemic issues in input validation and access control mechanisms.
Mitigation strategies should include immediate implementation of the provided patch dd77a35942f527ea0beef5e0ec62b92e8b93211e to address the sql injection vulnerability. Additionally, organizations should implement comprehensive input validation and parameter sanitization across all application functions that process user-supplied data. The principle of least privilege should be enforced, ensuring that administrative functions are properly secured and that access controls are robust. Regular security audits and penetration testing should be conducted to identify similar vulnerabilities in other application components. The vulnerability serves as a reminder of the critical importance of secure coding practices and the necessity of implementing proper database query parameterization to prevent sql injection attacks. Organizations should also consider implementing web application firewalls and intrusion detection systems to monitor for exploitation attempts. Security awareness training for developers should emphasize the importance of input validation and proper error handling to prevent similar vulnerabilities from being introduced in future code releases.
