"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.");
