Implement input validation
allAdd strict input validation and sanitization for zip file processing functions
🧯 If You Can't Patch
- Implement strict access controls to limit who can upload or process zip files
- Deploy application-level firewalls or WAF rules to detect and block command injection attempts
🔍 How to Verify
Check if Vulnerable:
Check if your system processes zip files and review code for command injection vulnerabilities in zip handling functionsCheck Version:
Check vendor documentation for specific version verification commandsVerify Fix Applied:
Test zip file processing with malicious payloads to ensure commands cannot be injected📡 Detection & Monitoring
Log Indicators:
- Unusual command execution patterns from zip processing applications
- Failed attempts to execute system commands via zip processing
Network Indicators:
- Unexpected outbound connections from zip processing services
- Command and control traffic from systems processing zip files
