Vulnerability Details

CVE-2025-49211:  SQL Injection Privilege Escalation Vulnerability 
ZDI-CAN-25528
CVSSv3.1: 7.7: AV:L/AC:H/PR:L/UI:N/S:C/C:L/I:H/A:H
Weakness: CWE-89: SQL Injection

A SQL injection vulnerability in the Trend Micro Endpoint Encryption PolicyServer could allow an attacker to escalate privileges on affected installations. 

Please note: an attacker must first obtain the ability to execute low-privileged code on the target system to exploit this vulnerability.

CVE-2025-49212:  Deserialization of Untrusted Data RCE Vulnerability 
ZDI-CAN-25507
CVSSv3.1: 9.8: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Weakness: CWE-477: Use of Obsolete Function

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-2025-49220 but is in a different method.

CVE-2025-49213:  Deserialization of Untrusted Data RCE Vulnerability 
ZDI-CAN-25506
CVSSv3.1: 9.8: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Weakness: CWE-477: Use of Obsolete Function

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-2025-49212 but is in a different method.

CVE-2025-49214:  Deserialization of Untrusted Data RCE Vulnerability 
ZDI-CAN-25518
CVSSv3.1: 8.8: AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Weakness: CWE-477: Use of Obsolete Function

An insecure deserialization operation in the Trend Micro Endpoint Encryption PolicyServer could lead to a post-authentication remote code execution on affected installations.

Please note: an attacker must first obtain the ability to execute low-privileged code on the target system to exploit this vulnerability.

CVE-2025-49215:  SQL Injection Privilege Escalation Vulnerability 
ZDI-CAN-25527
CVSSv3.1: 8.8: AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Weakness: CWE-242: Use of Inherently Dangerous Function

A post-auth SQL injection vulnerability in the Trend Micro Endpoint Encryption PolicyServer could allow an attacker to escalate privileges on affected installations. 

Please note: an attacker must first obtain the ability to execute low-privileged code on the target system to exploit this vulnerability.

CVE-2025-49216:  Authentication Bypass Vulnerability 
ZDI-CAN-25519
CVSSv3.1: 9.8: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Weakness: CWE-477: Use of Obsolete Function

An authentication bypass vulnerability in the Trend Micro Endpoint Encryption PolicyServer could allow an attacker to access key methods as an admin user and modify product configurations on affected installations. 

CVE-2025-49217:  Deserialization of Untrusted Data RCE Vulnerability 
ZDI-CAN-25505
CVSSv3.1: 9.8: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Weakness: CWE-477: Use of Obsolete Function

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.

CVE-2025-49218:  SQL Injection Privilege Escalation Vulnerability 
ZDI-CAN-25526
CVSSv3.1: 7.7: AV:L/AC:H/PR:L/UI:N/S:C/C:L/I:H/A:H
Weakness: CWE-89: SQL Injection

A post-auth SQL injection vulnerability in the Trend Micro Endpoint Encryption PolicyServer could allow an attacker to escalate privileges on affected installations. This is similar to, but not identical to CVE-2025-49215.

Please note: an attacker must first obtain the ability to execute low-privileged code on the target system to exploit this vulnerability.

Mitigating Factors

Exploiting these type of vulnerabilities generally require that an attacker has access (physical or remote) to a vulnerable machine. In addition to timely application of patches and updated solutions, customers are also advised to review remote access to critical systems and ensure policies and perimeter security is up-to-date.

However, even though an exploit may require several specific conditions to be met, Trend Micro strongly encourages customers to update to the latest builds as soon as possible.

In addition, due to the seriousness of these issues, Trend Micro also released some Network IPS rules/filters for proactive secondary protection for some of the vulnerabilities:

TippingPoint and Trend Micro Cloud One - Network Security:  Filters 45073, 45072
