Security readout for executives and security teams
Plain-English summary
This issue affects PingID Android app versions before 1.19 in environments using PingID Windows Login. A cryptographic misconfiguration could let an attacker bypass MFA offline, but the published CVSS vector indicates difficult conditions: physical access and high privileges are required. No source provided supports active exploitation.
Executive priority
Handle as a focused remediation item, not a broad emergency. The business concern is offline MFA bypass for a specific PingID Windows Login scenario. Confirm exposure quickly, enforce updated Android clients, and track exceptions for privileged or high-value workstation users.
Technical view
CVE-2021-41993 describes RSA misconfiguration in PingID Android before 1.19, enabling pre-computed dictionary attacks and offline MFA bypass with PingID Windows Login. CVSS 3.1 is 6.6 with AV:P/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:N. Public evidence does not include implementation details or exploit procedure.
Likely exposure
Exposure is likely limited to organizations using PingID Windows Login with Android PingID mobile clients older than 1.19. Risk is higher where mobile app version enforcement, device management, or privileged workstation access controls are weak.
Exploitation context
The source bundle does not show CISA KEV listing or other evidence of active exploitation. The CVSS vector suggests exploitation requires physical access, high privileges, and high attack complexity, reducing broad internet-scale risk but not eliminating targeted insider or local-access scenarios.
Researcher notes
Public detail is sparse. The CVE maps to CWE-310 and describes an RSA misconfiguration enabling pre-computed dictionary attacks. The affected scenario is specifically PingID Android before 1.19 with PingID Windows Login. Do not assume other PingID platforms are affected without vendor evidence.
Mitigation direction
- Upgrade affected PingID Android clients to version 1.19 or later where vendor guidance confirms availability.
- Review Ping Identity guidance for any additional remediation or configuration requirements.
- Enforce minimum mobile app versions through MDM or conditional access controls.
- Prioritize hosts using PingID Windows Login for remediation tracking.
Validation and detection
- Inventory Android PingID app versions across managed and unmanaged enrolled devices.
- Identify systems or user groups using PingID Windows Login.
- Confirm no active Windows Login users rely on PingID Android versions before 1.19.
- Review vendor documentation for product-specific verification guidance.
- Document exceptions and compensating controls for devices that cannot be updated.
