What is CVE-2025-40602?
CVE-2025-40602 is a local privilege escalation vulnerability affecting the management console of the SonicWall SMA1000 appliance. The SMA1000 is designed to facilitate secure remote access for users and is commonly utilized in enterprise environments to enable connectivity while maintaining robust security protocols. This vulnerability arises from insufficient authorization checks within the appliance's management console, which could allow an unauthorized user to escalate their privileges. The potential exploitation of this flaw would enable attackers to gain elevated access rights, which could lead to modifying system configurations, accessing sensitive data, or executing malicious commands, thereby compromising the integrity and confidentiality of the entire system.
