Horizon Alert
Summary of the vulnerability and why it matters
An origin validation vulnerability exists within the Apex One and SEP agent software. This flaw could enable a local attacker with low-privileged code execution to escalate their privileges on affected systems. This issue is related to a different communication mechanism than a previously identified vulnerability.
- Vulnerable agent software
- Weak origin validation
- Privilege escalation impact
Attack Path
How an attacker could exploit the issue
An origin validation vulnerability in the Apex One/SEP agent could allow a local attacker to escalate privileges. This issue is similar to a previously identified vulnerability but impacts a different communication mechanism. Exploitation requires an attacker to first gain the ability to execute low-privileged code on the affected system.
- Attacker executes low-privileged code.
- Attacker escalates privileges.
Live Threat
Current exploitation, exposure, and threat context
An origin validation vulnerability in Trend Micro Apex One/SEP agent could enable a local attacker to escalate privileges. This attack requires the attacker to first gain low-privileged code execution on the target system. Successful exploitation could impact system confidentiality, integrity, and availability.
- Likely attacker skill: Low.
- Required access: Low-privileged code execution.
- Business risk: High.
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability allows a local attacker to escalate privileges on affected installations by exploiting an origin validation flaw in the Apex One/SEP agent. Exploitation requires the attacker to already have low-privileged code execution on the target system.
- Identify affected assets.
- Reduce exposure or isolate risk.
- Fix, verify, and monitor.
