Multiple Vulnerabilities in Google Android OS Could Allow for Remote Code Execution

ITS Advisory Number: 
2021-126
Date(s) Issued: 
Tuesday, October 5, 2021
Subject: 
Multiple Vulnerabilities in Google Android OS Could Allow for Remote Code Execution
Overview: 

Multiple vulnerabilities have been discovered in the Google Android operating system (OS), the most severe of which could allow for remote code execution. 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 remote code execution within the context of a privileged process. 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 October  5, 2021.

Description: 

Multiple vulnerabilities have been discovered in Google Android OS, the most severe of which could allow for remote code execution within the context of a privileged process. 

Details of these vulnerabilities are as follows:

  • A vulnerability in Android runtime that could enable a local attacker with physical access to the device to execute arbitrary code in order to gain access to additional permissions. (CVE-2021-0703)
  • Multiple vulnerabilities in Framework that could enable a local malicious application to execute arbitrary code within the context of a privileged process. (CVE-2020-15358, CVE-2021-0651, CVE-2021-0652, CVE-2021-0702, CVE-2021-0705, CVE-2021-0708)
  • A vulnerability in Media Framework that could enable a local malicious application to execute arbitrary code within the context of a privileged process. (CVE-2021-0483)
  • Multiple vulnerabilities in System could enable a remote attacker using a specially crafted transmission to execute arbitrary code within the context of a privileged process. (CVE-2021-0870, CVE-2021-0643, CVE-2021-0706)
  • Multiple vulnerabilities in Kernel that could enable a local attacker to execute arbitrary code within the context of a privileged process. (CVE-2020-10768, CVE-2020-29368, CVE-2020-29660, CVE-2021-0707, CVE-2021-29647)
  • A vulnerability in Telecommunication that could lead to remote information disclosure with no additional execution privileges needed. (CVE-2021-27666)
  • Multiple Critical severity vulnerabilities in Qualcomm components. (CVE-2020-11264, CVE-2020-11301)
  • Multiple high severity vulnerabilities in Qualcomm components. (CVE-2020-2458, CVE-2020-24588, CVE-2020-26139, CVE-2020-26141, CVE-2020-26145, CVE-2020-26146, CVE-2021-1977, CVE-2021-1980, CVE-2021-30305, CVE-2021-30306, CVE-2021-30312)
  • Multiple high severity vulnerabilities in Qualcomm closed-source components. (CVE-2020-11303, CVE-2020-26140, CVE-2020-26147, CVE-2021-1913, CVE-2021-1917, CVE-2021-1932, CVE-2021-1936, CVE-2021-1949, CVE-2021-1959, CVE-2021-1983, CVE-2021-1984, CVE-2021-1985, CVE-2021-30256, CVE-2021-30257, CVE-2021-30258, CVE-2021-30288, CVE-2021-30291, CVE-2021-30292, CVE-2021-30297, CVE-2021-30302, CVE-2021-30310)

Successful exploitation of the most severe of these vulnerabilities could allow for remote code execution within the context of a privileged process. 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.
  • Inform and educate users regarding threats posed by hypertext links contained in emails or attachments, especially from un-trusted sources.
