CVE-2022-41570 is a critical security vulnerability identified in EyesOfNetwork (EON) versions up to and including 5.3.11. The vulnerability is an unauthenticated SQL injection (SQLi), classified under CWE-89, which allows an attacker to inject malicious SQL commands into the backend database without requiring any authentication or user interaction. This type of vulnerability arises when user-supplied input is improperly sanitized before being included in SQL queries, enabling attackers to manipulate the database queries executed by the application. Given the CVSS 3.1 base score of 9.8, this vulnerability is highly severe, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact scope is unchanged (S:U), but the confidentiality, integrity, and availability impacts are all high (C:H/I:H/A:H). Exploiting this vulnerability could allow an attacker to extract sensitive data, modify or delete data, or disrupt the availability of the EyesOfNetwork system. Although no known exploits are currently reported in the wild, the critical nature and ease of exploitation make it a significant threat. EyesOfNetwork is an open-source monitoring solution used for IT infrastructure monitoring, which often includes critical systems and network devices. The lack of vendor or product-specific details in the provided information suggests the vulnerability affects the core EON platform itself. The absence of patch links indicates that remediation may require applying updates from the official EyesOfNetwork project or implementing custom mitigations.

For European organizations, the impact of this vulnerability is substantial. EyesOfNetwork is used by various enterprises and public sector organizations for monitoring IT infrastructure, including servers, network devices, and applications. A successful SQL injection attack could lead to unauthorized access to sensitive monitoring data, manipulation of monitoring results, or complete disruption of monitoring services. This could hinder incident detection and response capabilities, potentially allowing attackers to operate undetected within the network. Critical sectors such as finance, healthcare, energy, and government agencies relying on EyesOfNetwork for operational monitoring could face data breaches, operational downtime, and compliance violations under GDPR due to unauthorized data exposure. The unauthenticated nature of the vulnerability means that attackers can exploit it remotely without credentials, increasing the risk of widespread exploitation. Additionally, the ability to alter or delete monitoring data could be leveraged to cover tracks during more extensive cyberattacks, compounding the threat to organizational security and resilience.

European organizations using EyesOfNetwork should prioritize the following mitigation steps: 1) Immediately assess the deployment of EyesOfNetwork versions up to 5.3.11 and plan for an upgrade to a patched version once available from the official EyesOfNetwork project. 2) Until patches are released, implement network-level protections such as restricting access to the EyesOfNetwork web interface to trusted IP addresses via firewall rules or VPN access to reduce exposure. 3) Employ Web Application Firewalls (WAFs) with SQL injection detection and prevention capabilities to monitor and block suspicious SQL injection attempts targeting the EyesOfNetwork interface. 4) Conduct thorough input validation and sanitization reviews if custom modifications or integrations exist, ensuring no unsanitized inputs reach SQL queries. 5) Monitor logs for unusual database query patterns or errors indicative of SQL injection attempts. 6) Establish incident response plans specifically addressing potential exploitation of monitoring infrastructure vulnerabilities. 7) Engage with the EyesOfNetwork community or vendor channels to stay informed about patches and advisories. These targeted actions go beyond generic advice by focusing on access control, proactive detection, and preparation specific to the nature of this vulnerability and the operational role of EyesOfNetwork.
