AI-suggested
Given the absence of an official patch at the time of disclosure, European organizations should implement immediate compensating controls. These include: 1) Restrict network access to the Trend Micro Endpoint Encryption Policy Server by implementing strict firewall rules and network segmentation to limit exposure to trusted management networks only. 2) Monitor network traffic and server logs for unusual or unauthorized deserialization attempts or anomalous activity indicative of exploitation attempts. 3) Employ application-layer firewalls or intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics capable of detecting deserialization attacks targeting this product. 4) Disable or restrict any unnecessary services or interfaces on the server to reduce the attack surface. 5) Engage with Trend Micro support to obtain any available hotfixes, patches, or recommended configuration changes as soon as they are released. 6) Prepare incident response plans specifically addressing potential exploitation scenarios of this vulnerability. 7) Conduct thorough inventory and risk assessment to identify all instances of the affected product version within the organization and prioritize remediation efforts accordingly.
Description
An insecure deserialization operation in the Trend Micro Endpoint Encryption PolicyServer could lead to a pre-authentication remote code execution on affected installations. Note that this vulnerability is similar to CVE-2025-49213 but is in a different method.
