CVE-2022-40722

7.7 HIGH

📋 TL;DR

This vulnerability allows attackers to bypass offline multi-factor authentication (MFA) in PingID Adapter for PingFederate through pre-computed dictionary attacks targeting RSA padding misconfiguration. Organizations using PingID mobile authenticators with offline MFA enabled are affected. The bypass could allow unauthorized access to protected systems.

💻 Affected Systems

Products:
  • PingID Adapter for PingFederate
Versions: Versions supporting offline MFA with PingID mobile authenticators prior to fixes
Operating Systems: All supported PingFederate platforms
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects configurations using offline MFA with PingID mobile authenticators

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete bypass of MFA protection, allowing unauthorized users to access sensitive systems and data without proper authentication.

🟠

Likely Case

Targeted attacks against high-value accounts to bypass MFA and gain unauthorized access to enterprise systems.

🟢

If Mitigated

Limited impact with proper network segmentation and additional authentication layers, though MFA bypass remains possible.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Requires ability to intercept or generate authentication attempts and perform pre-computed dictionary attacks

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: PingID Integration Kit 2.20 or later

Vendor Advisory: https://docs.pingidentity.com/r/en-us/pingid/pingid_integration_kit_2_20_rn

Restart Required: Yes

Instructions:

1. Update to PingID Integration Kit 2.20 or later. 2. Apply configuration changes per vendor documentation. 3. Restart PingFederate services. 4. Test offline MFA functionality.

🔧 Temporary Workarounds

Disable Offline MFA

all

Temporarily disable offline MFA functionality until patching can be completed

Configure PingFederate to disable offline MFA in PingID adapter settings

🧯 If You Can't Patch

  • Implement additional authentication controls such as IP restrictions or session timeouts
  • Monitor authentication logs for unusual patterns or failed MFA attempts

🔍 How to Verify

Check if Vulnerable:

Check PingID Integration Kit version and verify if offline MFA with PingID mobile authenticators is configured

Check Version:

Check PingFederate admin console or configuration files for PingID Integration Kit version

Verify Fix Applied:

Verify PingID Integration Kit version is 2.20 or later and test offline MFA functionality

📡 Detection & Monitoring

Log Indicators:

  • Multiple failed MFA attempts from same source
  • Successful authentication without proper MFA sequence
  • Unusual authentication patterns

Network Indicators:

  • Repeated authentication requests to PingFederate endpoints
  • Traffic patterns suggesting dictionary attacks

SIEM Query:

source="pingfederate" AND (event_type="authentication" AND mfa_status="bypassed" OR mfa_status="failed")
