Name of the Vulnerable Software and Affected Versions Asus ZenFone Max 4 Android device with a build fingerprint of asus/WW Phone/ASUS X00HD 4:7.1.1/NMF26F/14.2016.1803.373-20180308:user/release-keys

Description The issue concerns a pre-installed app with a package name of com.asus.loguploaderproxy that allows other pre-installed apps to perform command execution via an accessible app component. This capability can be accessed by any pre-installed app on the device that can obtain signatureOrSystem permissions required by other pre-installed apps that exported their capabilities to other pre-installed apps.

Recommendations For the Asus ZenFone Max 4 Android device, consider restricting access to the com.asus.loguploaderproxy app to minimize the risk of exploitation until a patch is available. As a temporary workaround, review and restrict the use of signatureOrSystem permissions for pre-installed apps to limit their ability to access exported capabilities.
