A privilege escalation vulnerability in the Trend Micro Apex One and Apex One as a Service agent could allow a local attacker to unintentionally delete privileged Trend Micro registry keys including its own protected registry keys on affected installations.

A security agent link following vulnerability in Trend Micro Apex One could allow a local attacker to exploit the vulnerability by changing a specific file into a pseudo-symlink, allowing privilege escalation on 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.

An issue in the Trend Micro Apex One agent could allow an attacker who has previously acquired administrative rights via other means to bypass the protection by using a specifically crafted DLL during a specific update process. Please note: an attacker must first obtain administrative access on the target system via another method in order to exploit this.

A security agent link following vulnerability in the Trend Micro Apex One agent could allow a local attacker to quarantine a file, delete the original folder and replace with a junction to an arbitrary location, ultimately leading to an arbitrary file dropped to an arbitrary location. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

A link following vulnerability in the scanning function of Trend Micro Apex One agent could allow a local attacker to escalate privileges on 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.

An improper access control vulnerability in the Trend Micro Apex One agent could allow a local attacker to gain elevated privileges and create arbitrary directories with arbitrary ownership.

An uncontrolled search path element vulnerability in the Trend Micro Apex One Server installer could allow an attacker to achieve a remote code execution state on affected products.

A directory traversal vulnerability in Trend Micro Apex One, OfficeScan (11.0, XG) and Worry-Free Business Security (9.5, 10.0) may allow an attacker to bypass authentication and log on to an affected product's management console as a root user. The vulnerability does not require authentication.

A directory traversal vulnerability in Trend Micro Apex One, OfficeScan (versions XG and 11.0), and Worry-Free Business Security (versions 10.0, 9.5 and 9.0) could allow an attacker to modify arbitrary files on the affected product's management console.
