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.

Directory traversal vulnerability in Trend Micro Office Scan 11.0, Worry-Free Business Security Service 5.x, and Worry-Free Business Security 9.0 allows remote attackers to read arbitrary files via unspecified vectors.

CRLF injection vulnerability in Trend Micro Worry-Free Business Security Service 5.x and Worry-Free Business Security 9.0 allows remote attackers to inject arbitrary HTTP headers and conduct cross-site scripting (XSS) attacks via unspecified vectors.

Directory traversal vulnerability in the UpdateAgent function in TmListen.exe in the OfficeScanNT Listener service in the client in Trend Micro OfficeScan 7.3 Patch 4 build 1367 and other builds before 1372, OfficeScan 8.0 SP1 before build 1222, OfficeScan 8.0 SP1 Patch 1 before build 3087, and Worry-Free Business Security 5.0 before build 1220 allows remote attackers to read arbitrary files via directory traversal sequences in an HTTP request. NOTE: some of these details are obtained from third party information.

The web management console in Trend Micro OfficeScan 7.0 through 8.0, Worry-Free Business Security 5.0, and Client/Server/Messaging Suite 3.5 and 3.6 creates a random session token based only on the login time, which makes it easier for remote attackers to hijack sessions via brute-force attacks. NOTE: this can be leveraged for code execution through an unspecified "manipulation of the configuration."
