AI-suggested
- Immediately monitor authentication logs for unusual login patterns, especially OAuth login attempts that may indicate crafted requests bypassing MFA.
- Enforce strict credential hygiene policies, including regular password changes and detection of credential leaks, to reduce the chance of attackers obtaining valid credentials.
- Implement network-level controls such as IP whitelisting or VPN requirements to limit access to Devolutions Server interfaces.
- Use additional layers of security such as endpoint detection and response (EDR) to detect anomalous activities post-login.
- Engage with Devolutions support to obtain timelines for patches and apply updates promptly once available.
- Consider temporary compensating controls like disabling OAuth login if feasible or enforcing alternative authentication methods until the vulnerability is patched.
- Educate users about phishing and credential theft risks to reduce the likelihood of credential compromise.
- Conduct regular penetration testing and vulnerability assessments focused on authentication mechanisms to identify similar weaknesses proactively.
Description
Improper authentication in the OAuth login functionality in Devolutions Server 2026.1.11 and earlier allows a remote attacker with valid credentials to bypass multi-factor authentication via a crafted login request.
