CVE-2020-14245
📋 TL;DR
CVE-2020-14245 is an authentication bypass vulnerability in HCL OneTest UI that allows unauthenticated attackers to access functionality requiring user identity or consume significant resources. Affected versions include V9.5, V10.0, and V10.1. This vulnerability enables unauthorized access to sensitive features without valid credentials.
💻 Affected Systems
- HCL OneTest UI
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through unauthorized access to administrative functions, data exfiltration, or resource exhaustion leading to denial of service.
Likely Case
Unauthorized access to sensitive testing data, configuration manipulation, or resource consumption attacks affecting application performance.
If Mitigated
Limited impact if network segmentation and access controls prevent external access to vulnerable interfaces.
🎯 Exploit Status
Authentication bypass vulnerabilities typically require minimal technical skill to exploit once the vulnerable endpoint is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply fixes from vendor advisory KB0086622
Vendor Advisory: https://support.hcltechsw.com/csm?id=kb_article&sysparm_article=KB0086622
Restart Required: Yes
Instructions:
1. Review HCL advisory KB0086622. 2. Download and apply the recommended patches. 3. Restart affected services. 4. Verify authentication is required for all sensitive functionality.
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to HCL OneTest UI to trusted networks only
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="TRUSTED_NETWORK" port protocol="tcp" port="PORT_NUMBER" accept'
netsh advfirewall firewall add rule name="Block OneTest UI" dir=in action=block protocol=TCP localport=PORT_NUMBER remoteip=any
Access Control Lists
linuxImplement IP-based access controls to limit who can reach the vulnerable interface
iptables -A INPUT -p tcp --dport PORT_NUMBER -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport PORT_NUMBER -j DROP
🧯 If You Can't Patch
- Isolate the HCL OneTest UI system from untrusted networks using firewall rules
- Implement network monitoring and alerting for unauthorized access attempts to the vulnerable interface
🔍 How to Verify
Check if Vulnerable:
Check if HCL OneTest UI version is 9.5, 10.0, or 10.1 and test if authentication is required for sensitive endpointsCheck Version:
Check application version in web interface or configuration filesVerify Fix Applied:
Verify the patch has been applied and test that authentication is now properly enforced on all endpoints📡 Detection & Monitoring
Log Indicators:
- Unauthenticated access to sensitive endpoints
- Failed authentication attempts followed by successful access
- Unusual resource consumption patterns
Network Indicators:
- Direct access to OneTest UI endpoints without authentication headers
- Unusual traffic patterns to testing interfaces
SIEM Query:
source="OneTest UI" AND (event_type="access" AND auth_status="none") OR (resource_usage > threshold)
