🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to the Disconf Configuration Center API endpoint (/api/config/list) to trusted IP addresses only.
iptables -A INPUT -p tcp --dport [DISCONF_PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [DISCONF_PORT] -j DROP
Web Application Firewall Rules
allImplement WAF rules to block unauthorized access to /api/config/list endpoint.
🧯 If You Can't Patch
- Implement strong authentication mechanisms before the Disconf API endpoint
- Monitor and alert on unauthorized access attempts to the /api/config/list endpoint
🔍 How to Verify
Check if Vulnerable:
Test if you can access http://[disconf-host]:[port]/api/config/list without authentication. If you get a response with configuration data, you are vulnerable.Check Version:
Check the Disconf version in the application configuration or deployment files.Verify Fix Applied:
After implementing workarounds, verify that unauthorized access to /api/config/list is blocked or requires proper authentication.📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to /api/config/list
- Unusual configuration data retrieval patterns
Network Indicators:
- Unusual traffic to /api/config/list endpoint from untrusted sources
SIEM Query:
source="disconf.log" AND (uri="/api/config/list" AND (response_code=200 OR auth_failure=false))
