CVE-2017-18071

Vulnerability

A debug policy bypass vulnerability exists in Qualcomm Snapdragon Mobile and Snapdragon Wear firmware used in Android devices. The affected chipsets include MDM9206, MDM9607, MSM8909W, SD 210/SD 212/SD 205, SD 425, SD 430, SD 450, SD 625, SD 650/52. In Android before the 2018-04-05 security patch level, the debug policy can potentially be bypassed [1]. The specific code path conditions required to trigger this vulnerability are not detailed in the available references.

Exploitation

An attacker with local access to the device or the ability to execute code on the device may be able to bypass the debug policy. The exact prerequisites and exploitation steps are not publicly disclosed in the available references [1]. The vulnerability may be exploitable without user interaction if the attacker has sufficient privileges.

Impact

Successful exploitation could lead to bypass of debug policy restrictions, which may allow an attacker to gain additional privileges or access restricted debugging interfaces. This could result in information disclosure or further compromise of the device [1]. The privilege level gained is unspecified but could be high due to the access provided by debug capabilities.

Mitigation

The vulnerability is addressed as part of the Android Security Bulletin for April 2018, with a security patch level of 2018-04-05 or later [1]. Users should ensure their devices receive the latest Android security updates from their device manufacturer. No workarounds are available if the patch is not applied.
