Description Preview

Econolite EOS traffic management software versions prior to 3.2.23 contain a critical security vulnerability where the system lacks password requirements for gaining "READONLY" access to log files and certain database and configuration files. This vulnerability is particularly severe as one of the accessible files contains tables with MD5 hashes and usernames for all defined users in the control software, including administrators and technicians. This could allow an attacker to obtain credential information and potentially gain unauthorized access to the traffic management system.

Overview

This vulnerability in Econolite EOS traffic management systems allows unauthorized users to access sensitive system files without proper authentication. By exploiting this vulnerability, attackers can gain "READONLY" access to log files, database files, and configuration files that contain sensitive information. Most critically, attackers can access files containing MD5 password hashes and usernames for all system users, including those with administrative privileges. Since MD5 hashes are considered cryptographically weak, these credentials could be cracked, potentially leading to full system compromise. This vulnerability affects critical infrastructure as Econolite EOS systems are commonly used for traffic management and control.

Remediation

  1. Update Econolite EOS to version 3.2.23 or later, which addresses this vulnerability by implementing proper authentication requirements.
  2. If immediate updating is not possible, implement network segmentation to restrict access to the affected systems.
  3. Monitor system logs for unauthorized access attempts.
  4. Consider changing all user passwords after updating to ensure previously compromised credentials cannot be used.
  5. Implement the principle of least privilege for all user accounts.
  6. Consider implementing additional authentication mechanisms such as multi-factor authentication where possible.
