🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation to sanitize user inputs before processing.
Implement input validation in application code (language-specific)
Content Security Policy
allImplement CSP headers to restrict script execution sources.
Add Content-Security-Policy header to web server configuration
🧯 If You Can't Patch
- Isolate Apifox instances in network segments with strict access controls
- Implement web application firewall (WAF) with XSS protection rules
🔍 How to Verify
Check if Vulnerable:
Check Apifox version in application settings or about dialog. If version is 2.1.6 or earlier, system is vulnerable.Check Version:
Check version in Apifox UI or configuration files (platform dependent)Verify Fix Applied:
Verify Apifox version is 2.1.7 or later after update. Test XSS payloads to confirm they are properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual script tags in request logs
- Suspicious JavaScript payloads in URLs or parameters
Network Indicators:
- HTTP requests containing script injection patterns
- Unusual outbound connections from Apifox instances
SIEM Query:
source="apifox" AND (http_request contains "<script>" OR http_request contains "javascript:")
