🛡️ CVE-2026-57588 - Nessus SQL Injection Exploitation Framework
📋 Table of Contents
🔍 Overview CVE-2026-57588 is a critical SQL injection vulnerability discovered in Tenable Nessus versions 10.12.0 and prior . The vulnerability resides in the XML parsing mechanism when importing .nessus scan result files, allowing authenticated users with import privileges to execute arbitrary SQL queries against the backend PostgreSQL database.
⚠️ Vulnerability Details Property Value CVE ID CVE-2026-57588 Vulnerability Type SQL Injection Affected Products Tenable Nessus 10.12.0 and prior Fixed Version Nessus 10.12.1 and later CVSS Score 4.3 (Medium) Attack Vector Network Attack Complexity Low Privileges Required Authenticated (Import permissions) User Interaction Required (Social engineering) Impact Data exfiltration, RCE
🔬 Technical Details The vulnerability exists due to insufficient sanitization of XML tag values before they are incorporated into SQL queries during the import process. A malicious actor can craft a .nessus file containing specially crafted SQL injection payloads in XML tags such as:
hostname
fqdn
os
system-type
mac-address
netbios-name
When a privileged user imports the malicious file, the unsanitized values are executed against the PostgreSQL backend, enabling:
Database enumeration
Data exfiltration
Command execution
File system access
Persistence installation

python3 exploit.py validate -p command_exec
# Then provide required parameters
python3 exploit.py generate -u https://test.com -p exec --command "whoami"
Issue 4: Permission Denied
# Error: Cannot write files
# Solution: Check directory permissions
chmod 755 ./outputs/
python3 exploit.py generate -u https://test.com -p enum -o ./outputs/scan.nessus
Issue 5: Timeout Issues
# Error: Operation timed out

🔐 Security Considerations
⚠️ Important Warnings
Legal Compliance : Only use on systems you own or have explicit written permission to test
Data Protection : Handle extracted credentials and data with extreme care
Isolated Environment : Always test in isolated lab environments
Backup : Always backup databases before testing
Restoration : Restore systems to original state after testing
Documentation : Document all testing activities for compliance
✅ Best Practices
Use dedicated testing accounts
Keep detailed logs of all actions
Use VPN/proxy for anonymity when testing third-party systems
Follow responsible disclosure guidelines
Educate your team about the vulnerability
