Successful exploitation allows execution of arbitrary code. 2) A boundary error in PolicyServer.exe can be exploited to cause a stack-based buffer overflow via an HTTP request to the cgiABLogon.exe CGI module with a specially crafted, overly long "pwd" parameter. Successful exploitation allows execution of arbitrary code but requires that the Trend Micro Policy Server for Cisco NAC is installed. Other errors, e.g. NULL-pointer dereference errors in certain CGI modules when handling HTTP requests containing certain characters or with invalid "Content-Length" headers, have also been reported. The vulnerabilities are confirmed in version 7.3 with Patch 3 build 1314. Other versions may also be affected. SOLUTION: Restrict network access to the services.
