Multiple Vulnerabilities in SonicWall GMS Could Allow for Remote Code Execution

📅 12 August 2026 at 17:20 UTC📰 CIS AdvisoriesView original source ↗

Multiple vulnerabilities have been discovered in SonicWall Global Management System (GMS), the most severe of which could allow for remote 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.
