CVE-2025-64327
📋 TL;DR
ThinkDashboard versions 0.6.7 and below contain a blind SSRF vulnerability in the /api/ping?url= endpoint that allows attackers to make arbitrary HTTP requests to internal and external systems. This can lead to network reconnaissance and potential data exposure. Anyone running vulnerable ThinkDashboard instances is affected.

⚠️ Risk & Real-World Impact
Worst Case
Attacker maps internal network, discovers sensitive services, and potentially accesses internal-only resources or pivots to other attacks.
Likely Case
Internal network reconnaissance revealing open ports, services, and internal IP addresses.
If Mitigated
Limited to external network scanning if proper network segmentation and egress filtering are in place.
🎯 Exploit Status
Simple HTTP request manipulation required. No authentication needed to access the vulnerable endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.6.8
Vendor Advisory: https://github.com/MatiasDesuu/ThinkDashboard/security/advisories/GHSA-p52r-qq3j-8p78
Restart Required: Yes
Instructions:
1. Stop ThinkDashboard service. 2. Update to version 0.6.8 via git pull or download release. 3. Restart ThinkDashboard service.
🔧 Temporary Workarounds
Block /api/ping endpoint
allUse web server or application firewall to block access to the vulnerable endpoint
# Example nginx location block
location /api/ping { deny all; }
Network egress filtering
linuxRestrict outbound connections from ThinkDashboard server to only necessary destinations
# Example iptables rule
iptables -A OUTPUT -p tcp -m owner --uid-owner thinkdashboard -d 127.0.0.1 --dport 80 -j ACCEPT
# Deny all other outbound from ThinkDashboard user
iptables -A OUTPUT -p tcp -m owner --uid-owner thinkdashboard -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate ThinkDashboard from sensitive internal networks
- Deploy web application firewall with SSRF protection rules
🔍 How to Verify
Check if Vulnerable:
Test if /api/ping?url=http://169.254.169.254/latest/meta-data/ returns data (AWS metadata endpoint test)Check Version:
Check ThinkDashboard version in web interface or run: ./thinkdashboard --versionVerify Fix Applied:
After patching, same test should return error or be blocked📡 Detection & Monitoring
Log Indicators:
- Multiple requests to /api/ping with different URL parameters
- Outbound connections from ThinkDashboard to internal IP ranges
Network Indicators:
- Unusual outbound HTTP traffic from ThinkDashboard server to internal IPs
- Port scanning patterns originating from ThinkDashboard server
