⌖ EXPLOITED IN THE WILD SHAME 45/100 exploited-in-wildsupply-chain

Trend Micro Apex One on-premise software allows local attackers to inject malicious code into agents via a directory traversal flaw.

A directory traversal vulnerability in Trend Micro Apex One (on-premise) enables local attackers to modify key tables and inject code into deployed agents, creating a supply-chain risk for DIB organizations relying on this endpoint protection platform. While not a zero-day or remote exploit, the ability to compromise agent integrity undermines the security posture of the entire endpoint ecosystem.

Shame score — A local-only vulnerability that requires pre-authentication, though it poses a supply-chain risk for endpoint security.

▸ RECOMMENDED ACTION  Actively exploited (CISA KEV) — remediate now, ahead of your normal patch cycle.

DESCRIPTION

Trend Micro Apex One (on-premise) contains a directory traversal vulnerability that could allow a pre-authenticated local attacker to modify a key table on the server to inject malicious code to deploy to agents on affected installations.
