SonicWall SMA 1000 Series <= 12.4.3-03453 / 12.5.x <= 12.5.0-02835 Multiple Vulnerabilities (SNWLID-2026-0016)

critical Nessus Plugin ID 342663

Synopsis

The remote device is affected by multiple vulnerabilities.

Description

The remote host is a SonicWall SMA 1000 Series device that is affected by multiple vulnerabilities:

 - A pre-authentication server-side request forgery (SSRF) vulnerability in the SMA1000 Appliance Work Place interface due to an unintended alternate access path. A remote, unauthenticated attacker could potentially exploit this to gain unauthorized access to sensitive functionality and perform unauthorized operations.
 (CVE-2026-83548)

 - A post-authentication improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerability in the SMA1000 Appliance Management Console (AMC) which, in specific conditions, could potentially enable a remote authenticated attacker as administrator to execute arbitrary OS commands, resulting in remote code execution. (CVE-2026-83549)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to SonicWall SMA 1000 Series version 12.4.3-03526 or 12.5.0-02952 or later.
