Halo Surface Signal score for CVE-2020-8655

This vulnerability requires local access to the system to exploit a misconfiguration in the sudoers file, which governs internal privilege escalation. It does not provide a mechanism for remote network-based exploitation in standard deployment scenarios.

Horizon Alert

Summary of the vulnerability and why it matters

The EyesOfNetwork application has a vulnerability within its sudoers configuration. This flaw could allow an attacker to execute commands with elevated privileges on the affected system. Such an escalation could lead to unauthorized access and manipulation of sensitive business data or critical system functions.

  • Vulnerable sudoers configuration
  • Allows arbitrary command execution as root
  • Business risk of data compromise or system disruption

Attack Path

How an attacker could exploit the issue

An attacker could exploit a misconfiguration in the sudoers file within EyesOfNetwork version 5.3. This misconfiguration allows the apache user to execute arbitrary commands with root privileges. The attack involves a specially crafted NSE script for nmap that leverages this vulnerability. Successful exploitation grants the attacker elevated permissions on the affected system.

  • Local access is required.
  • Attacker uses a crafted NSE script.
  • Apache user runs commands as root.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability presents a risk of privilege escalation, allowing an attacker to gain root access on affected systems. The exploitation requires specific conditions and attacker skill to execute arbitrary commands. Organizations should prioritize addressing this to mitigate potential damage.

  • Likely attacker skill level: Moderate
  • Required access or conditions: Local access, specific user account
  • Business risk or urgency: High, potential for full system compromise

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

An issue in EyesOfNetwork 5.3 presents a privilege escalation vulnerability. This means an attacker could potentially gain elevated access to the system. The vulnerability allows the apache user to execute arbitrary commands with root privileges through a specially crafted NSE script for nmap. This could lead to significant business risk if exploited.

  • Identify affected EyesOfNetwork assets.
  • Reduce exposure or isolate affected systems.
  • Apply vendor fix and validate.
  • Monitor for related security events.

Frequently asked questions

What is EyesOfNetwork 5.3 and what is it used for?

EyesOfNetwork is an application that includes network discovery and monitoring capabilities. Version 5.3 of this software is affected by a vulnerability related to its sudoers configuration, which controls user privileges on a system.

What type of weakness does CVE-2020-8655 represent?

CVE-2020-8655 is classified as an Improper Privilege Management vulnerability (CWE-269). This means it allows an attacker to perform actions beyond their authorized level, such as running commands as the root user.

How might an attacker exploit this EyesOfNetwork vulnerability?

An attacker would need local access to the system. They could then use a specially crafted Nmap Scripting Engine (NSE) script to trigger the vulnerability, allowing the apache user to run arbitrary commands as root.

Who should be concerned about CVE-2020-8655?

Organizations using EyesOfNetwork version 5.3 should be concerned. Halo Surface Signal indicates this vulnerability is internal, meaning it requires local access and is not typically exposed directly to the internet.

What is the first step to address this EyesOfNetwork vulnerability?

The first step is to identify any EyesOfNetwork version 5.3 assets within your environment. After identification, you should consider reducing their exposure or isolating them until a vendor fix can be applied.
