TrendAI Apex One Security Agent Local Privilege Escalation via Cache Mechanism (CVE-2025-71416)
TrendAI Apex One Security Agent is vulnerable to a local privilege escalation that allows an attacker with low‑privileged code execution to gain root privileges. The flaw stems from missing cache key validation during signature verification. Defenders should apply the vendor‑issued patch immediately and verify that the Apex One agent is updated.
What happened
TrendAI Apex One Security Agent contains a time‑of‑check/time‑of‑use flaw in its cache mechanism that can be abused to elevate privileges from a low‑privileged user to system level.
Impact
- Local attackers who can run code with limited privileges can exploit the flaw to gain root/administrator rights.
- Potential for arbitrary code execution in the context of the system account.
- CVSS score 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
Who is affected
All installations of TrendAI Apex One Security Agent that have not applied the vendor’s patch. The vulnerability is independent of the operating system but applies to any supported platform running the agent.
Mitigation
- Apply the TrendAI update that validates cache keys during signature verification.
- Verify the agent’s version and ensure it reflects the patched build.
- Restrict local code execution privileges and enforce least‑privilege policies until the patch is applied.
Next steps for defenders
Immediately check the agent version on all endpoints, deploy the vendor patch, and monitor for any signs of local privilege escalation attempts.
