CVE-2022-25260
📋 TL;DR
JetBrains Hub versions before 2021.1.14276 contain a blind Server-Side Request Forgery (SSRF) vulnerability that allows attackers to make unauthorized requests from the server to internal or external systems. This affects all organizations running vulnerable versions of JetBrains Hub, potentially exposing internal network resources or enabling data exfiltration.
💻 Affected Systems
- JetBrains Hub
📦 What is this software?
Hub by Jetbrains
⚠️ Risk & Real-World Impact
Worst Case
Attackers could pivot to internal systems, access sensitive data, or perform reconnaissance on internal networks by making the vulnerable server request internal resources.
Likely Case
Information disclosure from internal services, scanning of internal networks, or interaction with cloud metadata services to obtain credentials.
If Mitigated
Limited impact if network segmentation restricts outbound connections and internal services require authentication.
🎯 Exploit Status
SSRF vulnerabilities typically require minimal technical skill to exploit once the vulnerable endpoint is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2021.1.14276 and later
Vendor Advisory: https://www.jetbrains.com/privacy-security/issues-fixed/
Restart Required: Yes
Instructions:
1. Backup your Hub configuration and data. 2. Download the latest version from JetBrains website. 3. Stop the Hub service. 4. Install the updated version. 5. Start the Hub service. 6. Verify the version is 2021.1.14276 or later.
🔧 Temporary Workarounds
Network Restriction
allRestrict outbound network connections from the Hub server to only necessary destinations using firewall rules.
Reverse Proxy Filtering
allConfigure a reverse proxy to filter or block suspicious outbound requests from the Hub application.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the Hub server from sensitive internal systems
- Deploy a web application firewall (WAF) with SSRF protection rules
🔍 How to Verify
Check if Vulnerable:
Check the Hub version in the administration interface or via the API endpoint /api/rest/application/infoCheck Version:
curl -s http://hub-server/api/rest/application/info | grep versionVerify Fix Applied:
Confirm the version is 2021.1.14276 or higher and test that SSRF payloads no longer trigger outbound requests📡 Detection & Monitoring
Log Indicators:
- Unusual outbound HTTP requests from Hub server
- Requests to internal IP addresses or cloud metadata endpoints
Network Indicators:
- Hub server making unexpected connections to internal services
- Outbound requests to unusual domains or IPs
