Trend Micro Apex One Local Privilege Escalation

CVE advisorySeverity: HIGH (CVSS 7.8)

CVE-2025-71214

A flaw in Trend Micro Apex One's iCore service may allow a local attacker with existing low-privileged access to escalate privileges, potentially impacting data and system control. This vulnerability requires an attacker to first gain limited code execution on the target system. Affected organizations should assess the

Halo Surface Signal score for CVE-2025-71214

This vulnerability affects a local agent service on an endpoint. Exploitation requires an attacker to already have low-privileged code execution on the local system, making it inherently a local-only attack surface that is not reachable from the public internet.

Horizon Alert

Summary of the vulnerability and why it matters

The Trend Micro Apex One agent's iCore service contains a flaw related to origin validation. This weakness could allow a local attacker, who has already gained the ability to execute low-privileged code on a system, to escalate their privileges. Such an escalation could lead to unauthorized access and control over affected systems, potentially impacting data integrity and system availability.

  • Vulnerable Trend Micro agent service
  • Origin validation error
  • Local privilege escalation

Attack Path

How an attacker could exploit the issue

This vulnerability allows a local attacker to gain elevated privileges on an affected system. The attacker must first be able to execute low-privileged code on the target machine. Exploiting this involves an origin validation error within the Trend Micro Apex One agent's iCore service. Successful exploitation could lead to unauthorized access and control over the compromised system, impacting data confidentiality, integrity, and system availability.

  • Attacker obtains low-privileged code execution.
  • Exploits origin validation error.
  • Achieves privilege escalation.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability presents a local privilege escalation risk within Trend Micro Apex One (mac) agent installations. An attacker must already have low-privileged access to the affected system to initiate an attack. Successful exploitation could grant elevated privileges, potentially leading to unauthorized access and modification of system data. Organizations should review their security posture for this vulnerability.

  • Attacker skill: Moderate.
  • Access required: Local low-privileged code execution.
  • Business risk: Potential data compromise and system access.

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability presents a significant risk, potentially allowing a local attacker to escalate privileges on affected systems. Organizations should prioritize identifying all instances of the vulnerable software, as exploitation requires prior low-privileged code execution. Prompt action is essential to mitigate the potential impact on systems and data.

  • Locate all vulnerable assets.
  • Restrict access or isolate risk.
  • Apply vendor fixes and validate.
  • Monitor for related issues.

Frequently asked questions

What is the Trend Micro Apex One agent's iCore service?

The Trend Micro Apex One agent's iCore service is a component on protected systems that likely manages security functions and communications for the endpoint security solution.

What type of weakness does CVE-2025-71214 exhibit?

CVE-2025-71214 has an origin validation error, meaning it improperly checks the source of data or requests, potentially allowing an attacker to gain higher privileges.

How might a local attacker exploit this flaw?

A local attacker with low-privileged code execution can exploit this by leveraging the origin validation error to escalate their privileges on the affected Trend Micro Apex One agent.

What is the relevance of CVE-2025-71214 according to Halo Surface Signal?

Halo Surface Signal indicates this is an internal vulnerability, as exploitation requires an attacker to already have low-privileged code execution on the local system, making it not reachable from the public internet.

What steps should be taken to address this vulnerability?

Organizations should identify all vulnerable instances, restrict access or isolate risks, apply vendor fixes, and monitor for related issues to mitigate potential impacts on systems and data.
