Multiple Vulnerabilities in Juniper Products Could Allow for Remote Code Execution

Multiple vulnerabilities have been discovered in Juniper products, the most severe of which could allow for remote code execution. Juniper is a vendor for IT, networking and cybersecurity solutions. Successful exploitation of the most severe of these vulnerabilities could allow for remote code execution within the context of the application, an attacker gaining the same privileges as the logged-on user, or the bypassing of security restrictions. 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.

System Affected

  • Juniper Networks Junos OS
  • Junos Space and Junos Space Director prior to 20.1R1
  • Juniper Session and Resource Control prior to 4.12.0-R4, 4.13.0-R2

We recommend the following actions be taken:

  • Apply appropriate patches provided by Juniper to vulnerable systems 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 websites or follow links provided by unknown or untrusted 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.
