Multiple vulnerabilities have been discovered in Adobe products, the most severe of which could allow for arbitrary code execution.

• Animate is a multimedia authoring computer animation program.
• Bridge is a digital asset management application
• Illustrator is a vector graphics editor and design program.
• Adobe InCopy is a professional word processor.
• InDesign is an industry-leading layout and page design software for print and digital media.
• RoboHelp Server is a help authoring tool

‍

Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution. 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.

RECOMMENDATIONS:

We recommend the following actions be taken:

1. Apply the stable channel update provided by Adobe 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.

2. Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources. Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from un-trusted sources. (M1017: User Training)

 
• Safeguard  14.1: Establish and Maintain a Security Awareness Program: Establish and maintain a security awareness program. The purpose of a security      awareness program is to educate the enterprise’s workforce on how to interact with enterprise assets and data in a secure manner. Conduct training at hire and, at a minimum, annually. Review and update content annually, or when significant enterprise changes occur that could impact this Safeguard.
 
• Safeguard  14.2: Train Workforce Members to Recognize Social Engineering Attacks: Train workforce members to recognize social engineering attacks, such as phishing, pre-texting, and tailgating.

3. Apply the Principle of Least Privilege to all systems and services. Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack. (M1026: Privileged Account Management)    

 
• Safeguard 4.7: Manage Default Accounts on      Enterprise Assets and Software: Manage      default accounts on enterprise assets and software, such as root,      administrator, and other pre-configured vendor accounts. Example      implementations can include: disabling default accounts or making them      unusable.
 
• Safeguard 5.4: Restrict Administrator      Privileges to Dedicated Administrator Accounts: Restrict administrator privileges to      dedicated administrator accounts on enterprise assets. Conduct general      computing activities, such as internet browsing, email, and productivity      suite use, from the user’s primary, non-privileged account.

4. Block execution of code on a system through application control, and/or script blocking. (M1038 : Execution Prevention)    

 
• Safeguard 2.5 : Allow list Authorized Software: Use technical controls, such as application allow listing, to ensure that only authorized software can execute or be accessed. Reassess bi-annually, or more frequently.
 
• Safeguard 2.6 : Allow list Authorized Libraries: Use technical controls to ensure that only authorized software libraries, such as specific .dll, .ocx, .so, etc., files, are allowed to load into a system process. Block unauthorized libraries from loading into a system process. Reassess bi-annually, or more frequently.
 
• Safeguard 2.7 : Allowlist Authorized Scripts: Use technical controls, such as digital signatures and version control, to ensure that only authorized scripts, such as specific .ps1, .py, etc., files, are allowed to execute. Block unauthorized scripts from executing. Reassess bi-annually, or more frequently.

5. Restrict execution of code to a virtual environment on or in transit to an endpoint system. (M1048: Application Isolation and Sandboxing)    

 
• Safeguard 4.1 : Establish and Maintain a  Secure Configuration Process: Establish and maintain a secure configuration process for enterprise assets (end-user devices, including portable and mobile, non-computing/IoT devices, and servers) and software (operating systems and applications). Review and update documentation annually, or when significant enterprise changes occur that could impact this Safeguard.

6. Use capabilities to prevent suspicious behavior patterns from occurring on endpoint systems. This could include suspicious process, file, API call, etc. behavior. (M1040 : Behavior Prevention on Endpoint)    

 
• Safeguard 13.2 : Deploy a Host-Based Intrusion Detection Solution: Deploy a host-based intrusion detection solution on enterprise assets, where appropriate      and/or supported.

Safeguard 13.7: Deploy a Host-Based Intrusion Prevention Solution: Deploy a host-based intrusion prevention solution on enterprise assets, where appropriate and/or supported. Example implementations include use of an Endpoint Detection and Response (EDR) client or host-based IPS agent.
