CVE-2022-41571 is a critical security vulnerability identified in EyesOfNetwork (EON) versions up to 5.3.11. The vulnerability is a Local File Inclusion (LFI) flaw, which allows an unauthenticated remote attacker to include files from the local filesystem of the server running the vulnerable EON software. This can lead to the exposure of sensitive information, such as configuration files, credentials, or source code, and potentially enable further attacks like remote code execution if combined with other vulnerabilities or misconfigurations. The CVSS v3.1 base score of 9.8 reflects the high severity, indicating that the vulnerability is remotely exploitable over the network without any privileges or user interaction, and it impacts confidentiality, integrity, and availability. EyesOfNetwork is an open-source monitoring solution that integrates multiple monitoring tools and is used to monitor IT infrastructure and services. The lack of vendor and product details in the provided data suggests the vulnerability is specific to the EyesOfNetwork platform itself. The absence of known exploits in the wild as of the publication date does not diminish the critical nature of the vulnerability, as LFI flaws are often leveraged in targeted attacks once discovered. Given the nature of the vulnerability, attackers could potentially read arbitrary files, escalate privileges, or pivot within the network, severely compromising organizational security.

For European organizations using EyesOfNetwork for IT infrastructure monitoring, this vulnerability poses a significant risk. Compromise of monitoring systems can lead to undetected malicious activity, as attackers may manipulate monitoring data or disable alerts. The exposure of sensitive configuration files or credentials could facilitate lateral movement within corporate networks, increasing the risk of data breaches or ransomware attacks. Additionally, given the criticality of monitoring systems in maintaining operational continuity, exploitation could impact availability and integrity of monitoring data, potentially disrupting business operations. Organizations in sectors with stringent regulatory requirements, such as finance, healthcare, and critical infrastructure, could face compliance violations and reputational damage if this vulnerability is exploited. The remote and unauthenticated nature of the vulnerability increases the likelihood of exploitation, especially in environments where EyesOfNetwork instances are accessible from untrusted networks or the internet.

To mitigate CVE-2022-41571, European organizations should prioritize the following actions: 1) Immediately upgrade EyesOfNetwork to a version beyond 5.3.11 where the vulnerability is patched, once an official fix is available. 2) If patching is not immediately possible, restrict network access to the EyesOfNetwork management interfaces using firewalls or VPNs to limit exposure to trusted internal users only. 3) Implement strict input validation and sanitization on any user-supplied parameters related to file handling within the application, if custom modifications exist. 4) Conduct thorough audits of file permissions and configurations on servers running EyesOfNetwork to minimize sensitive file exposure. 5) Monitor logs and network traffic for unusual access patterns or attempts to exploit LFI vulnerabilities. 6) Employ web application firewalls (WAFs) with rules designed to detect and block LFI attack vectors targeting the EyesOfNetwork platform. 7) Educate IT and security teams about the risks associated with LFI vulnerabilities and ensure incident response plans include scenarios involving monitoring system compromises.
