CVE-2025-53884
📋 TL;DR
NeuVector stores user passwords and API keys using simple unsalted hashes, making them vulnerable to rainbow table attacks. This allows attackers who gain access to the hash database to easily crack credentials. All NeuVector deployments using affected versions are vulnerable.
💻 Affected Systems
- NeuVector
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of NeuVector administrative accounts leading to full control over container security policies, ability to disable security controls, and potential lateral movement to protected containers.
Likely Case
Attackers with database access can crack administrator passwords, gaining privileged access to modify security policies and potentially bypass container security controls.
If Mitigated
With proper network segmentation and access controls limiting database exposure, impact is reduced to credential exposure without immediate exploitation path.
🎯 Exploit Status
Exploitation requires access to the password hash database first, then offline cracking using rainbow tables or hashcat.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check NeuVector security advisory for specific patched versions
Vendor Advisory: https://github.com/neuvector/neuvector/security/advisories/GHSA-8ff6-pc43-jwv3
Restart Required: No
Instructions:
1. Update NeuVector to the latest patched version. 2. Force password resets for all users. 3. Rotate all API keys. 4. Verify new credentials are stored with proper salted hashing.
🔧 Temporary Workarounds
External Authentication
allConfigure NeuVector to use external authentication (LDAP, OIDC, SAML) instead of built-in authentication
Refer to NeuVector documentation for external auth configuration
Database Access Restriction
allRestrict access to NeuVector's database to only required services and administrators
Implement network segmentation and firewall rules to limit database access
🧯 If You Can't Patch
- Implement strict network segmentation to isolate NeuVector database from untrusted networks
- Enable multi-factor authentication and enforce strong password policies for all accounts
🔍 How to Verify
Check if Vulnerable:
Check if password hashes in NeuVector database are simple unsalted hashes (e.g., MD5, SHA-1 without salt)Check Version:
Check NeuVector version in web UI or via APIVerify Fix Applied:
Verify new password hashes use strong salted hashing algorithms (like bcrypt, scrypt, or PBKDF2)📡 Detection & Monitoring
Log Indicators:
- Unusual authentication attempts
- Multiple failed login attempts followed by successful login
- Database access from unauthorized sources
Network Indicators:
- Unexpected connections to NeuVector database port
- Large data transfers from database server
