    issue fixed in InstallBuilder 20.7.0.

    DLL planting vulnerability on InstallBuilder for Qt Windows installers

    InstallBuilder for Qt Windows installers are vulnerable to dll planting attacks.


    InstallBuilder for Qt Windows installers look for plugins at a predictable location at initialization time, writable by non-admin users. While those plugins are not required, they are loaded if present, which could allow an attacker to plant a malicious library which could result in code execution with the security scope of the installer. The attack requires previous access to the machine to be able to plant the malicious library at some point before the vulnerable installer is executed.


    Affected InstallBuilder for Qt customers should update to InstallBuilder 20.7.0 or later and release new versions.

    We would like to thank Hou JingYi (@hjy79425575) of Qihoo 360 CERT (https://houjingyi233.com/) for reporting the issue to us.

    VMware InstallBuilder

    As you might know in May 2019 BitRock was acquired by VMware Inc. Due to that, this week we have implemented a few changes you should know about. To start, you can now find the InstallBuilder website at https://installbuilder.com. Starting from version 20.2.2 InstallBuilder has been renamed to VMWare InstallBuilder. While the software can still be downloaded from the InstallBuilder website, from now on licenses need to be purchased trough the official VMWare store. The purchase section of our website will automatically redirect you to the right product in the VMware store: https://installbuilder.com/purchase.html. The types of licenses and the product's pricing have not changed and you can expect the same high level of quality of support and maintenance you are accustomed to.
    Here is the complete list of changes for VMware InstallBuilder 20.2:

    • Rebranded to VMware InstallBuilder
    • Improved timestamping error detection when signing macOS installers on non-macOS platforms
    • Prevent uninstaller from crashing when failing to check for empty directories because of lack of permissions


    Configure autoupdate project settings from the command line

    We have recently released InstallBuilder 19.11.0. With this update it's now possible to use --setvars with the autoupdate builder. This allows you to set different autoupdate project settings and variables from the command line variables in the command line. For example:

    ./autoupdate/bin/customize.run build autoupdate-project.xml linux-x64 --setvars autoupdate.installerFilename=sample.run

    Here is the complete list of improvements:

    • Updated HTTP/HTTPS internal dependencies
    • Improved AutoUpdate handling of malformed update.xml files [CVE-2020-3946]
    • Support --setvars command-line option when building the AutoUpdate
    • Support customizing license file location when building the AutoUpdate
    • Improved images rendering on macOS Builder
    • Improved Windows installers exit handling
    • Added .NET 4.8 autodetection
    • Updated documentation
    • Fixed <enableSsl> not honored on Windows at uninstallation time when using signed uninstallers
    • Fixed startmenu shortcuts not being created on windows-x64 installers
    • Fixed HTTP actions not honoring customized Accept header
    • Fixed false signing failure detection when building on macOS Catalina


    We have created a CVE entry (CVE-2020-3946) for the "AutoUpdate handling of malformed update.xml files" issue fixed in InstallBuilder 19.11.0, which could be exploited to crash the AutoUpdate process:

    Denial Of Service attack when checking for Updates
    InstallBuilder AutoUpdate tool and regular installers enabling <checkForUpdates> built with versions earlier than 19.11 are vulnerable to Billion laughs attack (denial-of-service).
    When checking for updates, the configured remote server is contacted to retrieve an XML containing information about the existing installer versions. This XML is then loaded in memory in the user machine. An attacker can forge a special XML exploiting entity expansion that will result in the AutoUpdate consuming system memory until it crashes.
    Exploiting this vulnerability requires an attacker to either place the malicious XML in the updates remote server (or to impersonate it via DNS spoofing) or by modifying the updates URL in the user machine updates.ini file.
    Affected InstallBuilder customers using the <checkForUpdates> functionality or distributing the AutoUpdate should update to version 19.11.0 or later and release new versions.

    Our engineers have evaluated this issue to have CVSSv3 score of 5.4

    We would like to thank Tesla Red Team for reporting this issue to us.
