An improper access control information disclosure vulnerability in Trend Micro Apex One and OfficeScan XG SP1 could allow an unauthenticated user to connect to the product server and reveal version and build information.

An improper access control information disclosure vulnerability in Trend Micro Apex One and OfficeScan XG SP1 could allow an unauthenticated user to connect to the product server and reveal the total agents managed by the server.

A vulnerability in Trend Micro OfficeScan XG SP1 on Microsoft Windows may allow an attacker to create a hard link to any file on the system, which then could be manipulated to gain a privilege escalation and code execution. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. This CVE is similar, but not identical to CVE-2020-24556.

A vulnerability in Trend Micro Apex One, Worry-Free Business Security 10.0 SP1 and Worry-Free Business Security Services on macOS may allow an attacker to manipulate a certain binary to load and run a script from a user-writable folder, which then would allow them to execute arbitrary code as root. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

An input validation vulnerability found in multiple Trend Micro products utilizing a particular version of a specific rootkit protection driver could allow an attacker in user-mode with administrator permissions to abuse the driver to modify a kernel address that may cause a system crash or potentially lead to code execution in kernel mode. An attacker must already have obtained administrator access on the target machine (either legitimately or via a separate unrelated attack) to exploit this vulnerability.

Trend Micro Apex One (2019), OfficeScan XG and Worry-Free Business Security (9.0, 9.5, 10.0) server contains a vulnerable service DLL file that could allow an attacker to delete any file on the server with SYSTEM level privileges. Authentication is not required to exploit this vulnerability.

A migration tool component of Trend Micro Apex One (2019) and OfficeScan XG contains a vulnerability which could allow remote attackers to execute arbitrary code on affected installations (RCE). An attempted attack requires user authentication.

Trend Micro Apex One (2019) and OfficeScan XG server contain a vulnerable EXE file that could allow a remote attacker to write arbitrary data to an arbitrary path on affected installations and bypass ROOT login. Authentication is not required to exploit this vulnerability.

Trend Micro Apex One (2019), OfficeScan XG and Worry-Free Business Security (9.0, 9.5, 10.0) server contains a vulnerable service DLL file that could allow a remote attacker to execute arbitrary code on affected installations with SYSTEM level privileges. Authentication is not required to exploit this vulnerability.

Trend Micro has repackaged installers for several Trend Micro products that were found to utilize a version of an install package that had a DLL hijack vulnerability that could be exploited during a new product installation. The vulnerability was found to ONLY be exploitable during an initial product installation by an authorized user. The attacker must convince the target to download malicious DLL locally which must be present when the installer is run.
