CVE-2022-23723
📋 TL;DR
This CVE describes an MFA bypass vulnerability in PingFederate's PingOne MFA Integration Kit when using adapter HTML templates in authentication flows. Attackers can potentially bypass multi-factor authentication requirements, compromising account security. Organizations using affected versions of PingFederate with PingOne MFA Integration Kit are vulnerable.
💻 Affected Systems
- PingFederate PingOne MFA Integration Kit
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete MFA bypass allowing unauthorized access to protected systems and sensitive data, potentially leading to account takeover, data breaches, and lateral movement within networks.
Likely Case
Targeted attackers bypass MFA to gain unauthorized access to user accounts, potentially accessing sensitive applications and data protected by PingFederate authentication.
If Mitigated
With proper monitoring and detection, unauthorized access attempts can be identified and blocked before significant damage occurs.
🎯 Exploit Status
Exploitation requires understanding of PingFederate authentication flows and access to modify or manipulate HTML templates in the MFA integration.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version 1.2.0 or later
Vendor Advisory: https://docs.pingidentity.com/bundle/pingfederate-pingone-mfa-ik/page/wpt1599064234202.html
Restart Required: Yes
Instructions:
1. Download PingOne MFA Integration Kit version 1.2.0 or later from Ping Identity's official resources. 2. Follow the upgrade instructions in the documentation. 3. Restart PingFederate services after installation. 4. Verify the update was successful.
🔧 Temporary Workarounds
Disable Adapter HTML Templates

Modify PingFederate configuration to use alternative authentication methods without HTML templates
Enhanced Monitoring
allImplement additional monitoring for authentication attempts and MFA bypass patterns.
Configure logging to capture detailed authentication events and MFA verification failures
🧯 If You Can't Patch
- Implement network segmentation to isolate PingFederate servers and limit access to critical systems
- Enhance monitoring and alerting for suspicious authentication patterns and MFA bypass attempts
🔍 How to Verify
Check if Vulnerable:
Check PingOne MFA Integration Kit version in PingFederate administration console. If version is below 1.2.0 and using adapter HTML templates, the system is vulnerable.Check Version:
Check version through PingFederate admin console or configuration files specific to PingOne MFA Integration Kit installation.Verify Fix Applied:
Verify PingOne MFA Integration Kit version is 1.2.0 or higher in PingFederate administration console and test authentication flows with MFA requirements.📡 Detection & Monitoring
Log Indicators:
- Unusual authentication patterns, MFA verification failures followed by successful logins, modifications to HTML template files
Network Indicators:
- Unusual authentication request patterns to PingFederate endpoints, bypass of MFA challenge steps
