Until an official patch is released, organizations should implement specific mitigations to reduce risk from CVE-2025-59502. First, restrict inbound network access to the RPC service (typically TCP ports 135 and dynamic RPC ports) using firewalls and network segmentation to limit exposure to untrusted networks. Employ intrusion detection and prevention systems (IDS/IPS) with updated signatures to detect anomalous or malformed RPC traffic indicative of exploitation attempts. Monitor system resource usage and RPC service logs for unusual spikes or errors that may signal attack activity. Disable or limit RPC services on systems where they are not required, especially on endpoints exposed to the internet or untrusted networks. Apply strict network access controls and enforce least privilege principles to reduce attack surface. Prepare for rapid patch deployment by inventorying affected systems and testing updates in controlled environments. Educate IT staff about this vulnerability to ensure prompt detection and response. Additionally, consider deploying endpoint detection and response (EDR) solutions capable of identifying abnormal process behavior related to resource exhaustion. Maintain regular backups and incident response plans to minimize operational impact in case of successful attacks.

Description

Uncontrolled resource consumption in Windows Remote Procedure Call allows an unauthorized attacker to deny service over a network.
