The advisory specifically impacts Apex One (on-premise) server/agent builds prior to 2019 (on-prem) build 17079 and Trend Vision One Endpoint - SEP agent builds prior to 14.0.20731. The advisory urges users and administrators to promptly review the provided resources and implement the recommended updates. This is important for defenders as unpatched systems remain vulnerable to exploitation, potentially leading to unauthorized access and compromise of systems protected by these products.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003cp\u003eDue to the lack of specific vulnerability details, a generic attack chain is provided, representing potential exploitation scenarios:\u003c/p\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker identifies a vulnerable Apex One or Trend Vision One Endpoint instance.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages a known or zero-day vulnerability to gain initial access.
