Name these files vsapi64.dll and BPMNT.dll and place them in a zip archive named engv_圆4dll_v9999-1004.zip.Ĭreate the fake server.ini file with the following contents. The following is a proof of concept to demonstrate the vulnerability:Ĭreate two DLL files that will open a reverse shell connection to the attacker's machine. Some interesting examples are the vsapi64.dll and BPMNT.dll files, which result in code execution in the context of the application, which is running with SYSTEM privileges. These packages are not signed or validated in any form other than matching the expected size described in the server.ini file.Īn attacker can overwrite sensitive files in the ScanMail's directory, including DLLs. However, the application allows users to configure alternative download sources to retrieve the packages. Update packages are signed and checked when they are downloaded from the ActiveUpdate server. Unvalidated Software Updates When Downloading from Alternative Sources This means that the product does not do any kind of certificate validation or public key pinning, which makes it easier for an attacker to eavesdrop and tamper the data. The application attempts to download a zip file named ini_xml.zip, which contains a server.ini file that describes from where to download engine updates, signatures, etc., as well as some metadata of each file.Īdditional updates are also downloaded via HTTP by default. Communication to the update servers is unencrypted. The vulnerabilities presented in sections 7.1 and 7.2 describe how an attacker could create a malicious update file to overwrite sensitive files and gain SYSTEM access. By exploiting vulnerabilities 7.3, 7.4, or 7.5, an attacker would be able to set an arbitrary download source and trigger the vulnerable update mechanism. This functionality can be configured from the Web-based console. This vulnerability is triggered when the update packages are downloaded from alternative sources instead of the ActiveUpdate servers. Trend Micro ScanMail for Exchange uses an insecure update mechanism that would allow an attacker to overwrite sensitive files, including binaries, and achieve remote code execution as SYSTEM. Technical Description / Proof of Concept Code The publication of this advisory was coordinated by Alberto Solino from Core Advisories Team.ħ. These vulnerabilities were discovered and researched by Leandro Barragan and Maximiliano Vidal from Core Security Consulting Services.
