InstallBuilder 22.10.0 released Nov 2

InstallBuilder version 22.10.0 has been released. Our engineers have been working on the following improvements and bug fixes:

  • Support using HTML values in <infoParameter> for all graphical modes
  • Added new <enableGlobMatching> setting to <deleteFile> action to allow deleting special filenames
  • Improved generation of unique identifiers
  • Improved DLL loading on Qt installers
  • Improved windows 32-bit runtimes to prevent false positives in some antivirus vendors
  • Updated documentation

UPDATE:

We have created a CVE entry for the “Improved DLL loading on Qt installers” (CVE-2022-31694) issue fixed in InstallBuilder 22.10.0.

DLL planting vulnerability in InstallBuilder for Qt installers (CVE-2022-31694 )

InstallBuilder for Qt Windows installers using dialog actions (popups) are vulnerable to DLL hijacking attacks.

Background

InstallBuilder Qt installers built with versions previous to 22.10 try to load DLLs from the installer binary parent directory when displaying popups. This may allow an attacker to plant a malicious DLL in the installer parent directory to allow executing code with the privileges of the installer (when the popup triggers the loading of the library.)

Exploiting these types of vulnerabilities generally requires that an attacker has access to a vulnerable machine to plant the malicious DLL.

Remediation

Affected InstallBuilder for Qt customers should update to InstallBuilder 22.10.0 or later and release new versions.

We would like to thank Marius Gabriel Mihai for reporting the issue.

UPDATE:

We have created two CVE entries for the “ Enforce full path to reg command on Windows” (CVE-2021-22037) and “ Improved uninstaller launching process on Windows” (CVE-2021-22038) issues fixed in InstallBuilder 21.6.0

Search Order Hijacking when performing registry actions ( CVE-2021-22037 )

InstallBuilder Windows installers are vulnerable to Path Interception by Search Order Hijacking

Background

Under certain circumstances, when manipulating the Windows registry, InstallBuilder uses the reg.exe system command. The full path to the command is not enforced, which results in a search in the search path until a binary can be identified. This makes the uninstaller vulnerable to Path Interception by Search Order Hijacking, potentially allowing an attacker to plant a malicious reg.exe command so it takes precedence over the system command, allowing execution with the security scope of the installer/uninstaller. 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.

The vulnerability only affects Windows installers.

Remediation

Affected InstallBuilder customers should update to InstallBuilder 21.6.0 or later and release new versions.

Binary planting at uninstall time (CVE-2021-22038 )

InstallBuilder Windows uninstallers are vulnerable to a binary planting attack

Background

On Windows, the uninstaller binary copies itself to a fixed temporary location, which is then executed (the originally called uninstaller then exits, so it does not block the installation directory). This temporary location is not randomized and does not restrict access to Administrators only so a potential attacker could plant a binary to replace the copied binary right before it gets called, thus allowing execution with the security scope of the uninstaller. The attack requires previous access to the machine and to monitor the temporary directory waiting to intercept the uninstaller binary.

Remediation

Affected InstallBuilder customers should update to InstallBuilder 21.6.0 or later and release new versions.

We would like to thank the Lockheed Martin Red Team and Zscaler for reporting the issue and helping us in testing the fixes.
