CVE-2026-66150 is a high severity code injection vulnerability in the SonicWall Email Security appliance. It allows an authenticated attacker with access to the restricted CLI to inject arbitrary operating system commands that execute with root privileges via SNMP. This vulnerability could lead to full system compromise if exploited.
AI Analysis
Technical Summary
This vulnerability involves improper control of code generation (CWE-94) in the SonicWall Email Security appliance. An attacker who is authenticated and has access to the restricted CLI can inject arbitrary OS commands through SNMP, which are executed as root. The CVSS 3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability. There is no information about affected versions or available patches. The vulnerability is not in a cloud service and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation allows an authenticated attacker to execute arbitrary OS commands as root on the SonicWall Email Security appliance. This can lead to complete compromise of the device, including unauthorized access, data disclosure, and disruption of email security functions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the SonicWall Email Security restricted CLI to trusted administrators only and monitor for unauthorized access attempts.
