The CVE-2017-14402 vulnerability represents a critical SQL injection flaw within the EyesOfNetwork web interface version 5.1-0, specifically targeting the user account management functionality. This vulnerability exists in the module/admin_user/add_modify_user.php component where the user_name parameter is processed without adequate input validation, creating a pathway for malicious actors to execute arbitrary SQL commands against the underlying database system. The flaw is particularly concerning as it resides within the account creation section, making it accessible to users with appropriate privileges who might be interacting with the system's administrative functions.
The technical implementation of this vulnerability stems from improper input sanitization practices within the include/function.php file, which serves as a critical library for handling various user inputs throughout the application. When an attacker submits a specially crafted user_name parameter containing SQL payload characters such as single quotes, semicolons, or union statements, the application fails to properly escape or validate these inputs before incorporating them into database queries. This lack of proper input validation creates a direct injection vector that allows attackers to manipulate the SQL execution flow and potentially gain unauthorized access to sensitive database information. The vulnerability aligns with CWE-89, which specifically addresses SQL injection weaknesses in software applications, and demonstrates a classic case of insufficient input sanitization in web applications.
The operational impact of this vulnerability extends beyond simple data theft, as successful exploitation could enable attackers to escalate privileges, modify user accounts, or even gain administrative access to the EyesOfNetwork system. Since the vulnerability affects the account creation functionality, attackers could potentially create new administrator accounts or modify existing ones to maintain persistent access. The database compromise could expose sensitive information including user credentials, system configurations, and potentially other interconnected system data. This vulnerability particularly impacts organizations relying on EyesOfNetwork for network monitoring and security management, as the compromised system could provide attackers with insights into network infrastructure and security events. The attack surface is further widened by the fact that this vulnerability affects a core administrative function, making it attractive to threat actors seeking to establish long-term access to network monitoring systems.
Organizations should implement immediate mitigations including input validation and sanitization of all user-supplied data, particularly in administrative functions where privilege escalation risks are highest. The recommended approach involves implementing proper parameterized queries or prepared statements to prevent SQL injection attacks, along with input filtering that removes or escapes dangerous characters from user inputs. Additionally, implementing proper access controls and privilege separation ensures that even if an attacker compromises one account, they cannot escalate privileges beyond the scope of their initial access. The mitigation strategy should align with ATT&CK technique T1078 which addresses valid accounts and privilege escalation, and CWE-89 which specifically addresses SQL injection vulnerabilities. Regular security assessments and penetration testing should be conducted to identify similar input validation flaws throughout the application, while also ensuring that all system components are updated to the latest security patches. Network segmentation and monitoring of administrative functions can provide additional layers of defense to detect and prevent exploitation attempts.
