AI-suggested
European organizations should immediately audit their Devolutions Server deployments to identify affected versions (2025.2.4.0 and earlier). Until a patch is released, organizations should implement strict monitoring of JIT access requests and approvals, focusing on anomalies such as approvals referencing deleted groups. Enforce multi-factor authentication (MFA) for all users with access to the JIT approval interface to reduce the risk of credential compromise. Limit the number of users authorized to approve JIT requests and implement strict role-based access controls (RBAC) to minimize the attack surface. Regularly review and clean up JIT Groups to reduce stale data that could be exploited. Enable detailed logging and alerting on JIT access activities to detect suspicious behavior promptly. Network segmentation and zero-trust principles should be applied to restrict access to the Devolutions Server management interface. Organizations should also prepare to apply patches immediately once available and consider vendor communication channels for early updates. Finally, conduct user training to raise awareness about the risks of stale UI states and the importance of verifying access requests carefully.
Description
UI synchronization issue in the Just-in-Time (JIT) access request approval interface in Devolutions Server 2025.2.4.0 and earlier allows a remote authenticated attacker to gain unauthorized access to deleted JIT Groups via stale UI state during standard checkout request processing.
