Multiple Vulnerabilities in Adobe Products Could Allow for Arbitrary Code Execution

ITS ADVISORY NUMBER:

DATE(S) ISSUED:

Wednesday, September 15, 2021

SUBJECT:
Multiple Vulnerabilities in Adobe Products Could Allow for Arbitrary Code Execution

OVERVIEW:

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

Adobe XMP Toolkit SDK is a development kit for Adobe's Extensible Metadata Platform.
Adobe Photoshop and Adobe Photoshop Elements is a graphics editor.
Adobe Experience Manager is a content management solution for building websites, mobile apps, and forms.
Adobe Genuine Service is a service that periodically verifies whether Adobe apps on your machine are genuine and notifies you if they are not.
Adobe Digital Editions is an e-book reader software program.
Adobe Premiere and Adobe Premiere Pro is a video editing software.
Adobe Creative Cloud is a cloud service provided by Adobe where its software can be accessed all in one place.
Adobe ColdFusion is a web application development platform.
Adobe Framemaker is a document processing software used to write and edit large or complex documents.
Adobe InDesign is an industry-leading layout and page design software for print and digital media.
Adobe SVG Native viewer is a library that parses and renders SVG Native documents.
Adobe InCopy is a professional word processor.
Acrobat and Reader is a family of application software and Web services mainly used to create, view, and edit PDF documents.

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.

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

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.

ACTIONS:

After appropriate testing, immediately install the updates provided by Adobe.
Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
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.
Apply the Principle of Least Privilege to all systems and services.
