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 OfficeScan versions 11.0 and XG (12.0) could be exploited by an attacker utilizing a directory traversal vulnerability to extract files from an arbitrary zip file to a specific folder on the OfficeScan server, which could potentially lead to remote code execution (RCE). The remote process execution is bound to a web service account, which depending on the web platform used may have restricted permissions. An attempted attack requires user authentication.

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.

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 vulnerability in Trend Micro Maximum Security's (Consumer) 2018 (versions 12.0.1191 and below) User-Mode Hooking (UMH) driver could allow an attacker to create a specially crafted packet that could alter a vulnerable system in such a way that malicious code could be injected into other processes.

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 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 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 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 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 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 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 DLL Hijacking vulnerability in Trend Micro's User-Mode Hooking Module (UMH) could allow an attacker to run arbitrary code on a vulnerable system.

An Unauthorized Memory Corruption vulnerability in Trend Micro OfficeScan 11.0 and XG may allow remote unauthenticated users who can access the OfficeScan server to target cgiShowClientAdm.exe and cause memory corruption issues.

Memory Corruption Privilege Escalation vulnerabilities in Trend Micro OfficeScan 11.0 and XG allows local attackers to execute arbitrary code and escalate privileges to resources normally reserved for the kernel on vulnerable installations by exploiting tmwfp.sys. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit the vulnerability.

A Host Header Injection vulnerability in Trend Micro OfficeScan XG (12.0) may allow an attacker to spoof a particular Host header, allowing the attacker to render arbitrary links that point to a malicious website with poisoned Host header webpages.

Pre-authorization Start Remote Process vulnerabilities in Trend Micro OfficeScan 11.0 and XG may allow unauthenticated users who can access the OfficeScan server to start the fcgiOfcDDA.exe executable or cause a potential INI corruption, which may cause the server disk space to be consumed with dump files from continuous HTTP requests.

Information disclosure vulnerabilities in Trend Micro OfficeScan 11.0 and XG may allow unauthenticated users who can access the OfficeScan server to query the network's NT domain or the PHP version and modules.

A potential Man-in-the-Middle (MitM) attack vulnerability in Trend Micro OfficeScan 11.0 and XG may allow attackers to execute arbitrary code on vulnerable installations.

A vulnerability in Trend Micro OfficeScan 11.0 and XG allows remote unauthenticated users who can access the system to download the OfficeScan encryption file.
