Multiple Vulnerabilities in SonicWall GMS Could Allow for Remote Code Execution

Multiple vulnerabilities have been discovered in SonicWall Global Management System (GMS), the most severe of which could allow forremote code execution.The SonicWall Global Management System (GMS) is a centralized management interface used to deploy and centrally manage SonicWall firewall, wireless, email security, secure remote access and Dell X-Series solutions from a single console. Successful exploitation of the most severe of these vulnerabilities could allow for remote code execution in the context of the affected service account. Depending on the privileges associated with the service account, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Services whose accounts are configured to have less 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.

Multiple vulnerabilities have been discovered in SonicWall Global Management System (GMS), the most severe of which could allow for remote code execution. Details of these vulnerabilities are as follows:

Tactic: Initial Access (TA0001)

Technique: Exploit Public-Facing Application (T1190)

Successful exploitation of these vulnerabilities could allow for remote code execution in the context of the affected service account. Depending on the privileges associated with the service account an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Services whose accounts are configured to have fewer rights on the system could be less impacted than those who operate with administrative rights.
