CVE-2024-0392
📋 TL;DR
A Cross-Site Request Forgery (CSRF) vulnerability in WSO2 Enterprise Integrator 6.6.0 management console allows attackers to trick authenticated users into performing unauthorized state-changing operations. This affects administrators and users with access to the management console, potentially compromising account settings and data integrity.
💻 Affected Systems
- WSO2 Enterprise Integrator
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could modify administrator accounts, change system configurations, or manipulate data through authenticated user sessions, potentially leading to full system compromise.
Likely Case
Attackers would modify limited account settings or configurations through social engineering, requiring user interaction with malicious content while authenticated.
If Mitigated
With proper CSRF protections and user awareness, exploitation would be prevented despite the vulnerability existing.
🎯 Exploit Status
Requires social engineering to trick authenticated users into clicking malicious links while logged into management console.

4. Verify CSRF token validation is enabled
🔧 Temporary Workarounds
Implement CSRF Protection Headers
allAdd CSRF protection headers to management console responses
Configure web server to add 'X-Frame-Options: DENY' header
Configure 'Content-Security-Policy: frame-ancestors 'none''
Session Timeout Reduction
allReduce session timeout to limit exposure window
Edit repository/conf/tomcat/carbon/WEB-INF/web.xml to reduce session-timeout
🧯 If You Can't Patch
- Implement network segmentation to restrict management console access to trusted IPs only
- Enable multi-factor authentication for all management console users
- Implement web application firewall with CSRF protection rules
- Educate users about phishing and social engineering risks
🔍 How to Verify
Check if Vulnerable:
Check if management console endpoints lack CSRF token validation by inspecting requests/responsesCheck Version:
Check WSO2 EI version in management console or via product documentationVerify Fix Applied:
Verify CSRF tokens are required for state-changing operations in management console📡 Detection & Monitoring
Log Indicators:
- Multiple state-changing requests from same session without CSRF tokens
- Unusual configuration changes from unexpected user sessions
Network Indicators:
- HTTP POST requests to management console endpoints without CSRF tokens
- Referer header mismatches in management console requests
SIEM Query:
source="wso2-ei" AND (http_method="POST" OR http_method="PUT") AND NOT csrf_token=* AND uri="/carbon/*"
