Multiple Vulnerabilities in VMware SD-WAN Orchestrator Could Allow for Arbitrary Code Execution

ITS Advisory Number: 
2020-158
Date(s) Issued: 
Thursday, November 19, 2020
Subject: 
Multiple Vulnerabilities in VMware SD-WAN Orchestrator Could Allow for Arbitrary Code Execution
Overview: 

Multiple vulnerabilities have been discovered in VMware SD-WAN Orchestrator, the most severe of which could allow for arbitrary code execution. Successful exploitation of the most severe of these vulnerabilities could result in an attacker gaining the same privileges given to the host machine. Depending on the privileges associated with VMware SD-WAN Orchestrator, 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.

Systems Affected: 
  • VMware SD-WAN Orchestrator versions prior to 4.0.1, 3.4.4, and 3.3.2 P3

Description: 

Multiple vulnerabilities have been discovered in VMWare SD-WAN Orchestrator, the most severe of which could allow for arbitrary code execution. Details of these vulnerabilities are as follows:

  • The SD-WAN Orchestrator does not apply correct input validation which allows for SQL-injection (CVE-2020-3984)

  • The SD-WAN Orchestrator allows for executing files through directory traversal (CVE-2020-4000)

  • The SD-WAN Orchestrator has default passwords allowing for a Pass-the-Hash Attack (CVE-2020-4001)

  • The SD-WAN Orchestrator allows an access to set arbitrary authorization levels leading to a privilege escalation issue (CVE-2020-3985)

  • The SD-WAN Orchestrator handles system parameters in an insecure way (CVE-2020-4002)

  • The SD-WAN Orchestrator was found to be vulnerable to SQL-injection attacks allowing for potential information disclosure (CVE-2020-4003) 

Successful exploitation of the most severe of these vulnerabilities could result in an attacker gaining the same privileges given to the host machine. Depending on the privileges associated with VMware SD-WAN Orchestrator, 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: 
  • Change all default passwords on the predefined accounts.

  • After appropriate testing, immediately apply the patches/mitigation provided by VMware to the vulnerable systems.

  • Run all software as a non-privileged user to diminish effects of a successful attack.

  • Inform and educate users regarding threats posed by hypertext links contained in emails or attachments especially from untrusted sources.

  • Remind all users not to visit untrusted websites or follow links provided by unknown or untrusted sources.

  • Apply the Principle of Least Privilege to all systems and services.
