A Vulnerability in Android OS Could Allow for Remote Code Execution
MS-ISAC ADVISORY NUMBER:
2024-124DATE(S) ISSUED:
11/07/2024OVERVIEW:
A vulnerability has been discovered in Android OS that 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 this vulnerability could allow for remote code execution in the context of the logged-on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
THREAT INTELLIGENCE:
Google reports that CVE-2024-43093 has been exploited in the wild.
SYSTEMS AFFECTED:
- Android OS Patch levels prior to 2024-11-01
RISK:
Government:
Businesses:
Home Users:

Tactic: Execution (TA0002)
Technique: Exploitation for Client Execution (T1203):
- A vulnerability in the System could allow for remote code execution. (CVE-2024-43093)
Successful exploitation of this vulnerability could allow for remote code execution in the context of the system. Depending on the privileges associated with the system, an attacker could then install programs; view, change, or delete data.
RECOMMENDATIONS:
We recommend the following actions be taken:
- Apply appropriate mitigations provided by Google to vulnerable systems immediately after appropriate testing. (M1051: Update Software)
- Safeguard 7.1: Establish and Maintain a Vulnerability Management Process: Establish and maintain a documented vulnerability management process for enterprise assets. Review and update documentation annually, or when significant enterprise changes occur that could impact this Safeguard.
- Safeguard 7.4: Perform Automated Application Patch Management: Perform application updates on enterprise assets through automated patch management on a monthly, or more frequent, basis.
- Safeguard 7.5: Perform Automated Vulnerability Scans of Internal Enterprise Assets: Perform automated vulnerability scans of internal enterprise assets on a quarterly, or more frequent, basis. Conduct both authenticated and unauthenticated scans, using a SCAP-compliant vulnerability scanning tool.
- 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. (M1017: User Training)
- Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring. (M1050: Exploit Protection)
- Safeguard 10.5: Enable Anti-Exploitation Features: Enable anti-exploitation features on enterprise assets and software, where possible, such as Apple® System Integrity Protection (SIP) and Gatekeeper™.
- Safeguard 13.10 : Perform Application Layer Filtering: Perform application layer filtering. Example implementations include a filtering proxy, application layer firewall, or gateway.
