CVE-2018-5384 in Infinity Web Interface
Summary
by MITRE
Navarino Infinity web interface up to version 2.2 exposes an unauthenticated script that is prone to blind sql injection. If successfully exploited the user can get info from the underlying postgresql database that could lead into to total compromise of the product. The said script is available with no authentication.

The vulnerability identified as CVE-2018-5384 affects the Navarino Infinity web interface version 2.2 and earlier, presenting a critical security flaw that stems from improper authentication mechanisms and weak input validation. This issue resides within the web application's script execution environment where an unauthenticated endpoint allows arbitrary code execution through blind sql injection techniques. The vulnerability is particularly concerning because it eliminates any requirement for authentication, making it accessible to any attacker with network access to the affected system. The exposed script serves as an attack vector that bypasses the application's normal security controls, creating a direct pathway into the underlying database infrastructure. This flaw represents a fundamental breakdown in the application's security architecture, where the lack of proper access controls combined with insufficient input sanitization creates a dangerous combination that can be exploited by malicious actors without requiring any credentials or prior access privileges.
The technical implementation of this vulnerability demonstrates a classic blind sql injection attack pattern where the attacker can infer database contents through indirect means rather than direct data retrieval. The affected script operates without authentication requirements, meaning that any external party can submit malicious sql payloads that will execute against the PostgreSQL database backend. This type of vulnerability falls under the CWE-89 category of SQL Injection, specifically manifesting as a blind injection where the attacker must deduce database information through response timing or conditional responses. The vulnerability's exploitation potential increases significantly because the database connection is likely configured with sufficient privileges to allow data extraction, modification, or even command execution capabilities. The blind nature of the injection means that attackers must craft their payloads carefully, using techniques such as conditional statements or time-based queries to determine if their injection was successful and to extract information from the database through iterative processes.
The operational impact of this vulnerability extends far beyond simple data theft, as successful exploitation can lead to complete system compromise of the Navarino Infinity product. An attacker who successfully exploits this vulnerability gains access to sensitive operational data, user credentials, configuration information, and potentially system-level access that could enable further lateral movement within the network. The PostgreSQL database exposure creates a significant risk for organizations relying on this security product, as the compromise of the database could reveal information about network topology, user accounts, or other sensitive operational details. The lack of authentication requirements means that this vulnerability can be exploited by automated scanning tools, making it particularly dangerous in environments where such systems are exposed to the internet. The compromise of the underlying database could also impact the integrity of security logs, configuration files, and other critical system data, potentially weakening the overall security posture of the affected organization.
Mitigation strategies for CVE-2018-5384 should prioritize immediate implementation of authentication controls and input validation measures to prevent unauthorized access to the vulnerable script. Organizations should implement proper access controls that require authentication before any script execution can occur, effectively closing the gap that allows unauthenticated exploitation. The remediation process must include comprehensive input sanitization and parameterized queries to prevent sql injection attacks from succeeding. Security teams should also consider implementing network segmentation to limit access to the vulnerable system and deploy web application firewalls to monitor and filter malicious requests. The vulnerability aligns with ATT&CK technique T1190 for Exploit Public-Facing Application and T1071.004 for Application Layer Protocol: DNS, as attackers may use these methods to probe and exploit the vulnerable interface. Additionally, the remediation efforts should include regular security assessments, vulnerability scanning, and ensuring that all systems are updated to versions that address this specific flaw. Organizations should also implement monitoring solutions to detect unusual database access patterns that might indicate exploitation attempts and establish incident response procedures to handle potential breaches resulting from this vulnerability.
