Local Privilege Escalation Vulnerability in SonicWall SMA1000 Appliance Management Console

CVE-2025-40602

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.

Potential impact of CVE-2025-40602

1. Unauthorized System Access: The vulnerability permits unauthorized users to escalate privileges, enabling them to gain control over the SonicWall appliance's management console. This access could lead to unauthorized changes, compromising the device’s functionality and security measures.

2. Data Exposure and Integrity Risks: With elevated privileges, an attacker could access sensitive data processed or stored within the SMA1000. Such exposure of confidential information could result in data breaches that might have severe legal and financial repercussions for an organization.

3. Wider Network Compromise: Exploiting this vulnerability could create a pathway for attackers to infiltrate broader network infrastructures connected to the SMA1000 appliance. This foothold could be used to launch further attacks, propagate malware, or compromise additional systems within the organization.
