SonicWall SMA 1000 Series <= 12.4.3-03526 / 12.5.x <= 12.5.0-02952 Multiple Vulnerabilities (SNWLID-2026-0017)

critical Nessus Plugin ID 364476

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. By abusing this path, a remote, unauthenticated attacker could potentially direct the appliance to issue requests on their behalf and reach internal functionality and perform unauthorized operations. (CVE-2026-102255)

- A Zip Slip vulnerability in the SMA1000 Appliance Management Console (AMC) interface allows an attacker to extract files outside the intended destination directory using a specially crafted archive, resulting in remote code execution. (CVE-2026-102257)

- A post-authentication improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerability in the SMA1000 appliance which, in specific conditions, could potentially enable a remote authenticated attacker as administrator to execute arbitrary OS commands, resulting in remote code execution. (CVE-2026-102256)

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 12.4.3-03670 or 12.5.0-03082 or later.
