ITS ADVISORY NUMBER:

2022-019

DATE(S) ISSUED:

Tuesday, February 8, 2022

SUBJECT:

Multiple Vulnerabilities in Google Android OS Could Allow for Escalation of Privilege

OVERVIEW:

Multiple vulnerabilities have been discovered in the Google Android operating system (OS), the most severe of which could allow for escalation of privilege. Android is an operating system developed by Google for mobile devices, including, but not limited to, smartphones, tablets, and watches. Successful exploitation of the most severe of these vulnerabilities could allow for escalation of privilege. Depending on the privileges associated with this application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.

THREAT INTELLIGENCE:

There are currently no reports of these vulnerabilities being exploited in the wild.

SYSTEMS AFFECTED:

Android OS builds utilizing Security Patch Levels issued prior to February 5, 2022

RISK:

Government:

Large and medium government entities: High

Small government entities: High

Business:

Large and medium business entities: High

Small business entities: High

Home Users: Low

DESCRIPTION:

Multiple vulnerabilities have been discovered in Google Android OS, the most severe of which could allow for escalation of privilege. Details of these vulnerabilities are as follows:

Multiple vulnerabilities in Framework, The most severe vulnerability in this section could lead to local escalation of privilege with no additional execution privileges needed. (CVE-2021-39619, CVE-2021-39662, CVE-2021-39663, CVE-2021-39676, CVE-2021-39664)
A vulnerability in Media Framework, the most severe vulnerability in this section could lead to local escalation of privilege with no additional execution privileges needed. (CVE-2020-13112, CVE-2020-13113, CVE-2021-39665, CVE-2021-39666)
Multiple vulnerabilities in System, The most severe vulnerability in this section could lead to remote escalation of privilege with no additional execution privileges needed. (CVE-2021-39675, CVE-2021-39668, CVE-2021-39669, CVE-2021-39671, CVE-2021-39674, CVE-2021-0706)
Multiple vulnerabilities in Project Mainline components. (CVE-2021-39662, CVE-2021-39663)
A vulnerability in System could lead to local information disclosure with no additional execution privileges needed. (CVE-2021-39631)
A vulnerability in Amlogic components. (CVE-2021-39672)
Multiple vulnerabilities in MediaTek components. (CVE-2022-20024, CVE-2022-20025, CVE-2022-20026, CVE-2022-20027, CVE-2022-20028,)
A vulnerability in Unisoc components. (CVE-2021-39616, CVE-2021-39635, CVE-2021-39658)
Multiple high severity vulnerabilities in Qualcomm components. (CVE-2021-35068, CVE-2021-35069, CVE-2021-35074, CVE-2021-35075, CVE-2021-35077)
Multiple high and critical severity vulnerabilities in Qualcomm closed-source components. (CVE-2021-30317, CVE-2021-30309, CVE-2021-30318, CVE-2021-30322, CVE-2021-30323, CVE-2021-30326)

Successful exploitation of the most severe of these vulnerabilities could allow for escalation of privilege. Depending on the privileges associated with this application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.

ACTIONS:

After appropriate testing, immediately apply updates by Google Android or mobile carriers to vulnerable systems.
Remind users to only download applications from trusted vendors in the Play Store.
Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
