Cybersecurity Advisory: Several Vulnerabilities Identified in Google Android OS

Cybersecurity Advisory: Several Vulnerabilities Identified in Google Android OS

A cybersecurity warning was issued yesterday, Sept. 4, 2018, regarding several security flaws discovered in the Google Android operating system (OS) that could allow for remote code execution.

What It Is:
Android is an operating system developed by Google for mobile devices including, but not limited to, smartphones, tablets, and watches. Multiple vulnerabilities have been discovered in the Google Android OS, the most severe of which could allow for remote code execution. 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 the 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.

See the original Security Bulletin.

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

What It Means:
If your business or organization utilizes Android OS in smartphones, tablets, watches or other mobile devices, you will need to install the security updates immediately to address these vulnerabilities to prevent a possible security breach.

Systems Affected Include:
• Android OS builds utilizing Security Patch Levels issued prior to September 5, 2018.

Risk:
Government:
• Large and medium government entities: High
• Small government entities: High
Businesses:
• Large and medium business entities: High
• Small business entities: High
Home users: High

Technical Summary:
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 remote code vulnerability in Android Runtime. (CVE-2018-9466)
• An elevation of privilege vulnerability in Android Runtime. (CVE-2018-9467)
• An information disclosure vulnerability in Framework. (CVE-2018-9468)
• Multiple elevation of privilege vulnerabilities in Framework. (CVE-2018-9469, CVE-2018-9470, CVE-2018-9471)
• An information disclosure vulnerability in Kernel components. (CVE-2017-5754)
• A remote code vulnerability in Library. (CVE-2018-9472)
• Multiple remote code vulnerabilities in Media Framework. (CVE-2018-9411, CVE-2018-9427)
• A denial of service vulnerability in Media Framework. (CVE-2018-9440)
• An elevation of privilege vulnerability in Media Framework. (CVE-2018-9474)
• Multiple vulnerabilities in Qualcomm closed-source components. (CVE-2016-10394, CVE-2016-10408, CVE-2017-18124, CVE-2017-18311, CVE-2017-18312, CVE-2017-18313, CVE-2017-18314, CVE-2018-11285, CVE-2018-11287, CVE-2018-11288, CVE-2018-11290, CVE-2018-11292, CVE-2018-11824, CVE-2018-11846, CVE-2018-11855, CVE-2018-11857, CVE-2018-11858, CVE-2018-11865, CVE-2018-11866, CVE-2018-11950, CVE-2018-11951, CVE-2018-11952, CVE-2018-3588, CVE-2018-5866, CVE-2018-5871, CVE-2018-5914)
• Multiple vulnerabilities in Qualcomm components. (CVE-2017-15825, CVE-2018-11261, CVE-2018-11270, CVE-2018-11816, CVE-2018-11836, CVE-2018-11842, CVE-2018-11898)
• Multiple denial of service vulnerabilities in System. (CVE-2018-9456, CVE-2018-9487)
• Multiple elevation of privilege vulnerabilities in System. (CVE-2018-9475, CVE-2018-9477, CVE-2018-9478, CVE-2018-9479, CVE-2018-9488)
• Multiple information disclosure vulnerabilities in System. (CVE-2018-9480, CVE-2018-9481, CVE-2018-9482, CVE-2018-9483, CVE-2018-9484, CVE-2018-9485, CVE-2018-9486)

Successful exploitation of the most severe of these vulnerabilities could allow for remote code execution in the context of a privileged process. These vulnerabilities could be exploited through multiple methods such as email, web browsing, and MMS when processing media files. Depending on the privileges associated with the 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.

What To Do:
We recommend the following actions be taken:
• Apply appropriate updates by Google Android or mobile carriers to vulnerable systems, immediately after appropriate testing, when they become available.
• Remind users to only download applications from trusted vendors in the Play Store.
• Remind users not to visit untrusted websites or follow links provided by unknown or untrusted sources.
• Inform and educate users regarding threats posed by hypertext links contained in emails or attachments, especially from untrusted sources.

Negative Consequences of Lost or Stolen Data Include:
The loss or theft of proprietary data can have severe impacts, particularly if the compromise becomes public and sensitive information is exposed. Possible impacts include:
• Temporary or permanent loss of sensitive or proprietary information
• Disruption to regular operations
• Financial losses incurred to restore systems and files
• Potential harm to an organization’s reputation
