CVE-2025-49154: An insecure access control vulnerability in Trend Micro Apex One and Trend Micro Worry-Free Business Security could allow a local attacker t
Noroxi assessment
Priority: Monitor (action score 31/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.12% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Trend Micro, Inc. Trend Micro Apex One 14.0.0.14002; Trend Micro, Inc. Trend Micro Apex One as a Service 14.0.14492; Trend Micro, Inc. Worry-Free Business Security 2514.
Low priority for now. Upgrade to Trend Micro, Inc. Trend Micro Apex One 14.0.0.14002; Trend Micro, Inc. Trend Micro Apex One as a Service 14.0.14492; Trend Micro, Inc. Worry-Free Business Security 2514 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
An insecure access control vulnerability in Trend Micro Apex One and Trend Micro Worry-Free Business Security could allow a local attacker to overwrite key memory-mapped files which could then have severe consequences for the security and stability of affected installations. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
No history yet (it accumulates with the daily EPSS job).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
