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.

A Trend Micro OfficeScan XG weak file permissions vulnerability may allow an attacker to potentially manipulate permissions on some key files to modify other files and folders on vulnerable installations.

A Trend Micro OfficeScan XG weak file permissions vulnerability on a particular folder for a particular group may allow an attacker to alter the files, which could lead to other exploits on vulnerable installations.

A pool corruption privilege escalation vulnerability in Trend Micro OfficeScan 11.0 SP1 and XG could allow a local attacker to escalate privileges on vulnerable installations due to a flaw within the processing of IOCTL 0x220078 in the TMWFP driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

A vulnerability in Trend Micro OfficeScan 11.0 SP1 and XG could allow a attacker to take a series of steps to bypass or render the OfficeScan Unauthorized Change Prevention inoperable on vulnerable installations. An attacker must already have administrator privileges in order to exploit this vulnerability.

A vulnerability in Trend Micro OfficeScan 11.0 SP1 and XG could allow a attacker to exploit it via a Browser Refresh attack on vulnerable installations. An attacker must be using a AD logon user account in order to exploit this vulnerability.

A out-of-bounds read information disclosure vulnerability in Trend Micro OfficeScan 11.0 SP1 and XG could allow a local attacker to disclose sensitive information on vulnerable installations due to a flaw within the processing of IOCTL 0x220004 by the TMWFP driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

A pool corruption privilege escalation vulnerability in Trend Micro OfficeScan 11.0 SP1 and XG could allow a local attacker to escalate privileges on vulnerable installations due to a flaw within the processing of IOCTL 0x2200B4 in the TMWFP driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

A pool corruption privilege escalation vulnerability in Trend Micro OfficeScan 11.0 SP1 and XG could allow a local attacker to escalate privileges on vulnerable installations due to a flaw within the processing of IOCTL 0x220008 in the TMWFP driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

A vulnerability in Trend Micro OfficeScan 11.0 SP1 and XG could allow a attacker to use a specially crafted URL to elevate account permissions on vulnerable installations. An attacker must already have at least guest privileges in order to exploit this vulnerability.

A vulnerability in Trend Micro Apex One and OfficeScan XG could allow an attacker to expose a masked credential key by manipulating page elements using development tools. Note that the attacker must already have admin/root privileges on the product console to exploit this vulnerability.

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.

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.

A DLL side-loading vulnerability in Trend Micro OfficeScan 11.0 SP1 and XG could allow an authenticated attacker to gain code execution and terminate the product's process - disabling endpoint protection. The attacker must have already gained authentication and have local access to the vulnerable system.
