Trend Micro's Virus Scan API (VSAPI) and Advanced Threat Scan Engine (ATSE) - are vulnerable to a memory exhaustion vulnerability that may lead to denial-of-service or system freeze if exploited by an attacker using a specially crafted file.

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.

A Named Pipe Request Processing Out-of-Bounds Read Information Disclosure vulnerability in Trend Micro OfficeScan XG (12.0) could allow a local attacker to disclose sensitive information on vulnerable installations. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit the vulnerability.

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

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.

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.

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.

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.

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.
