⚠️ Risk & Real-World Impact
Worst Case
Remote code execution on the HikCentral server if CSV data is processed with elevated privileges, potentially compromising the entire system.
Likely Case
Local command execution on the server when malicious CSV files are imported by administrators or users with import privileges.
If Mitigated
Limited impact if CSV import functionality is restricted to trusted users and input validation is implemented.
🎯 Exploit Status
Exploitation requires ability to upload/import CSV files; typically requires some level of access to the system's import functionality.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Hikvision security advisory for specific patched versions
Vendor Advisory: https://www.hikvision.com/en/support/cybersecurity/security-advisory/security-vulnerabilities-in-some-hikcentral-products/
Restart Required: Yes
Instructions:

🔧 Temporary Workarounds
Restrict CSV Import Access
allLimit CSV import functionality to trusted administrators only and implement strict user access controls.
Input Validation for CSV Files
allImplement server-side validation to sanitize CSV input and reject files containing formula or command characters.
🧯 If You Can't Patch
- Disable CSV import functionality entirely if not required for operations.
- Implement network segmentation to isolate HikCentral systems from critical infrastructure.
🔍 How to Verify
Check if Vulnerable:
Check HikCentral Master Lite version against the vulnerable versions listed in Hikvision's security advisory.Check Version:
