CVE-2025-69929 N3uron CVE debrief

Who should care

Organizations using N3uron Web User Interface v.1.21.7-240207.1047 or earlier versions should prioritize patching this vulnerability to prevent potential privilege escalation attacks. This includes operators of the affected system, platform administrators, vulnerability management teams, and security teams responsible for ensuring the security and integrity of their systems.

Technical summary

The vulnerability is caused by the use of MD5 algorithm for password hashing on the client side, which is a weak hashing algorithm that can be easily exploited by attackers. The predictable string format used for password hashing makes it easier for attackers to escalate privileges. This issue was reported by Jose Abreu and publicly disclosed on GitHub. The vendor, N3uron, has provided a mitigation guide on their website. To address this vulnerability, it is essential to update the password hashing algorithm to a more secure one, such as bcrypt or Argon2, and implement additional security measures to prevent privilege escalation attacks.

Defensive priority

High

Recommended defensive actions

• Apply the patch provided by the vendor to update the password hashing algorithm to a more secure one
• Use a Web Application Firewall (WAF) to detect and prevent potential attacks
• Monitor the system for suspicious activity and implement additional security measures to prevent privilege escalation attacks
• Consider using a more secure password hashing algorithm such as bcrypt or Argon2
• Perform regular security audits and penetration testing to identify and address potential vulnerabilities

Evidence notes
