The vulnerability CVE-2020-9465 represents a critical SQL injection flaw within the EyesOfNetwork eonweb web interface version 5.1 through 5.3 before 5.3-3. This security weakness affects a widely used network monitoring and vulnerability management platform that organizations rely on for critical infrastructure protection. The vulnerability exists in the web application's handling of user authentication tokens, specifically within the user_id field of cookies, creating a pathway for unauthorized access to the system's administrative functions.
The technical implementation of this flaw stems from improper input validation and sanitization within the web application's authentication mechanism. When users interact with the EyesOfNetwork eonweb interface, the system stores user identification information in cookies, particularly within the user_id field. An attacker exploiting this vulnerability can manipulate the cookie value to inject malicious SQL commands that bypass normal authentication procedures. This occurs because the application fails to properly escape or validate user-supplied input before incorporating it into database queries, directly violating established security principles for input handling and query construction.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it enables complete authentication bypass for unauthenticated attackers. Once exploited, the vulnerability allows malicious actors to gain administrative privileges without requiring valid credentials, potentially leading to full system compromise. Attackers could manipulate the database to extract sensitive information, modify user accounts, alter system configurations, or even inject backdoors for persistent access. The vulnerability's severity is amplified by its unauthenticated nature, meaning that any individual with access to the web interface can exploit this flaw without prior authorization or credentials.
The exploitation of this vulnerability aligns with attack patterns documented in the MITRE ATT&CK framework under the credential access and defense evasion techniques, particularly focusing on credential dumping and privilege escalation. From a CWE perspective, this vulnerability maps directly to CWE-89 SQL injection, which represents one of the most prevalent and dangerous web application security flaws. Organizations using EyesOfNetwork eonweb in production environments face significant risk of data breaches, system compromise, and regulatory compliance violations when this vulnerability remains unpatched. The affected versions span multiple releases, indicating a prolonged exposure window where organizations could have been vulnerable without awareness of the security gap.
Organizations should immediately implement patch management procedures to upgrade to EyesOfNetwork eonweb version 5.3-3 or later, which contains the necessary fixes for this vulnerability. Additional mitigations include implementing web application firewalls to monitor and block suspicious SQL injection patterns, disabling unnecessary web interface access where possible, and conducting comprehensive security assessments of the network monitoring infrastructure. Network segmentation and access control measures should be strengthened to limit potential lateral movement if exploitation occurs. Regular security audits and penetration testing of critical infrastructure monitoring systems are essential to identify and remediate similar vulnerabilities before they can be exploited by threat actors.
