CVE-2024-7073
📋 TL;DR
This CVE describes a server-side request forgery (SSRF) vulnerability in multiple WSO2 products that allows unauthenticated attackers to manipulate server-side requests. Attackers can access internal and external resources available through the network or filesystem, potentially exposing sensitive data and systems. All organizations running affected WSO2 products with SOAP admin services exposed are at risk.
💻 Affected Systems
- WSO2 API Manager
- WSO2 Identity Server
- WSO2 Enterprise Integrator
- WSO2 Micro Integrator
- WSO2 Streaming Integrator
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of internal network resources, data exfiltration from backend systems, and potential lateral movement to other critical infrastructure.
Likely Case
Unauthorized access to internal APIs, metadata services, and file systems accessible from the vulnerable server, leading to data exposure.
If Mitigated
Limited impact due to network segmentation, proper input validation, and restricted server permissions.
🎯 Exploit Status
SSRF vulnerabilities typically have low exploitation complexity; attackers need network access to vulnerable endpoints.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to vendor advisory for specific patched versions per product
Vendor Advisory: https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2024/WSO2-2024-3562
Restart Required: Yes
Instructions:
1. Review vendor advisory for affected product versions. 2. Apply recommended patches or updates. 3. Restart affected services. 4. Verify fix implementation.
🔧 Temporary Workarounds
Network Segmentation
linuxRestrict network access to SOAP admin services using firewall rules
iptables -A INPUT -p tcp --dport [SOAP_PORT] -j DROP
ufw deny [SOAP_PORT]
Input Validation
allImplement strict input validation for SOAP requests
🧯 If You Can't Patch
- Implement strict network segmentation to isolate vulnerable systems
- Deploy web application firewall (WAF) with SSRF protection rules
🔍 How to Verify
Check if Vulnerable:
Check if SOAP admin services are accessible and review version against vendor advisoryCheck Version:
Check product documentation for version command (varies by WSO2 product)Verify Fix Applied:
Verify patched version is installed and test SSRF attempts are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SOAP requests to admin services
- Requests to internal IP addresses from SOAP endpoints
- Failed SSRF attempts in application logs
Network Indicators:
- Outbound connections from WSO2 servers to internal resources initiated by SOAP requests
- Unusual port scanning from WSO2 servers
SIEM Query:
