Calling an executable through an Uncontrolled Search Path Element in the Bosch Video Streaming Gateway installer up to and including version 6.45.10 potentially allows an attacker to execute arbitrary code on a victim's system. A prerequisite is that the victim is tricked into placing a malicious exe in the same directory where the installer is started from.
InstallBuilder for Qt Windows (versions prior to 20.7.0) 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.
Adobe Acrobat and Reader versions 2020.006.20034 and earlier, 2017.011.30158 and earlier, 2017.011.30158 and earlier, 2015.006.30510 and earlier, and 2015.006.30510 and earlier have an insecure library loading (dll hijacking) vulnerability. Successful exploitation could lead to privilege escalation.
Untrusted DLLs in the installer's directory may be loaded and executed, leading to potentially arbitrary code execution with the installer's privileges (admin).
