Adobe Products could allow for Arbitrary Code Execution

Dec 15, 2021

Multiple vulnerabilities have been discovered in Adobe products, the most severe of which could allow for Arbitrary Code Execution.

  • Premiere Rush is a video editor.
  • Experience Manager is a comprehensive content management solution for building websites, mobile apps and forms.
  • Connect is a suite of software for remote training, web conferencing, presentation, and desktop sharing.
  • Photoshop is a graphics editor.
  • Prelude software is a video ingest and logging tool that helps you quickly tag and transcode raw footage from file-based cameras.
  • After Effects is a graphics and visual effects software.
  • Dimension is a 3D rendering and design software
  • Premiere Pro is a video editing and manipulation software.
  • Media Encoder is software that provides media content over the internet.
  • Lightroom is an image organization and manipulation tool.
  • Audition is a professional audio editing application that includes a non-destructive mixing and editing environment.

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.

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

RECOMMENDATIONS:

We recommend the following actions be taken:

  • Install the updates provided by Adobe immediately after appropriate testing.
  • 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.
