CVE-2020-8655 is a high-severity vulnerability affecting EyesOfNetwork 5.3. This vulnerability allows the apache user to exploit a misconfiguration in the sudoers file to execute arbitrary commands with root privileges using a specially crafted Nmap Scripting Engine (NSE) script. The CVSS score of 7.8 indicates a significant risk, as it enables attackers to compromise system security, potentially leading to unauthorized access and control.
The vulnerability was published on February 7, 2020, and has since been analyzed for its potential impact. Given the exploits available, organizations using EyesOfNetwork are at an elevated risk if they do not address this issue promptly. Organizations should prioritize patching immediately.
Risk to organizations includes the possibility of attackers leveraging this vulnerability to gain root access, which could lead to data breaches, system manipulation, and further exploitation of network resources. The urgency for defenders to take action cannot be overstated.
The threat landscape remains active, with proof-of-concept (PoC) exploits found in exploit databases, indicating that malicious actors may be ready to exploit this vulnerability. As such, immediate remediation should be a focal point for all organizations running affected versions.
Vulnerability Details
An issue was discovered in EyesOfNetwork 5.3. The sudoers configuration is prone to a privilege escalation vulnerability, allowing the apache user to run arbitrary commands as root via a crafted NSE script for nmap 7.
The vulnerability has a CVSS score of 7.8 indicating a high severity level, with the following metrics: attack vector is local, attack complexity is low, and no privileges are required. User interaction is required, which adds a layer of complexity to the attack scenario.
This vulnerability is classified under CWE-269, which pertains to improper privilege management. Organizations using the affected version should take immediate action to mitigate this risk.
Technical Analysis
The root cause of this vulnerability lies in the misconfigured sudoers file, which allows insufficiently restricted access to the apache user. Attackers can exploit this misconfiguration by executing a crafted NSE script. The attack vector is local, as it requires access to the system where EyesOfNetwork is installed.
The attack complexity is low, meaning that the attack can be executed without sophisticated techniques. No privileges are required to exploit this vulnerability, but user interaction is necessary to execute the malicious script. The confidentiality, integrity, and availability impacts are all high, indicating that a successful exploitation could lead to serious consequences.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2020-8655 is significant. Organizations running EyesOfNetwork 5.3 must recognize that the ability for an attacker to gain root access through privilege escalation can lead to a complete compromise of the system.
The potential blast radius is extensive; if exploited, attackers could not only access sensitive data but also manipulate or delete critical system components. The urgency for organizations to respond is critical, particularly in light of the high CVSS score and the existence of known exploits.
Organizations should address this issue in their priority patch cycle to mitigate risks. Given the exploitability, there is a real threat that attackers may leverage this vulnerability to gain unauthorized access.
