CVE-2022-27919
📋 TL;DR
CVE-2022-27919 is a critical remote code execution vulnerability in Gradle Enterprise that allows attackers to execute arbitrary code on affected systems. Organizations running Gradle Enterprise installations without proper initial configuration files are vulnerable. This affects systems where anonymous access to administration and API endpoints is permitted.
💻 Affected Systems
- Gradle Enterprise
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands, steal sensitive data, deploy malware, or pivot to other systems in the network.
Likely Case
Unauthorized access leading to data exfiltration, installation of backdoors, or disruption of build processes.
If Mitigated
Limited impact with proper access controls and configuration hardening in place.
🎯 Exploit Status
Exploitation is straightforward once the vulnerable configuration is identified. The advisory includes technical details that could be weaponized.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2022.1 and later
Vendor Advisory: https://security.gradle.com/advisory/2022-05
Restart Required: Yes
Instructions:
1. Upgrade Gradle Enterprise to version 2022.1 or later. 2. Verify configuration files properly restrict anonymous access. 3. Restart the Gradle Enterprise service.
🔧 Temporary Workarounds
Restrict Anonymous Access
allConfigure Gradle Enterprise to require authentication for all administrative and API endpoints.
Edit configuration to set 'anonymousAccessEnabled: false' in security settings
Network Segmentation
allRestrict network access to Gradle Enterprise instances using firewalls or network policies.
Configure firewall rules to limit access to trusted IP addresses only
🧯 If You Can't Patch
- Implement strict network access controls to limit exposure
- Enable comprehensive logging and monitoring for suspicious API/admin access
🔍 How to Verify
Check if Vulnerable:
Check Gradle Enterprise version and verify if configuration allows anonymous administrative access.Check Version:
Check Gradle Enterprise admin interface or configuration files for version informationVerify Fix Applied:
Confirm version is 2022.1 or later and anonymous access to admin/API endpoints is disabled.📡 Detection & Monitoring
Log Indicators:
- Unauthenticated access to administrative endpoints
- Unusual API calls from unknown sources
- Execution of unexpected system commands
Network Indicators:
- Unusual traffic patterns to Gradle Enterprise admin ports
- Requests to administrative endpoints without authentication headers
SIEM Query:
source="gradle-enterprise" AND (event_type="admin_access" OR event_type="api_call") AND user="anonymous"
