Executive Summary

This vulnerability exists in the createSessionInternal function of PackageInstallerService.java. It involves a path traversal error that allows an attacker to update a Device Policy Controller (DPC) into an invalid directory.

Because of this path traversal issue, an attacker can escalate their local privileges without needing any additional execution privileges or user interaction.

Impact Analysis

The vulnerability can lead to local escalation of privilege, meaning an attacker with limited access could gain higher privileges on the affected device.

Since no user interaction or additional execution privileges are needed, the attacker could exploit this vulnerability silently and potentially gain unauthorized control over device policies.
