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 privilege escalation vulnerability due to improper neutralization of special elements used in an SQL command. A remote authenticated attacker with read-only administrator privileges can escalate privileges to primary administrator. (CVE-2026-4112)

 - An observable response discrepancy vulnerability that allows a remote attacker to enumerate SSL VPN user credentials. (CVE-2026-4113)

 - An improper handling of Unicode encoding vulnerability that allows a remote authenticated SSLVPN admin to bypass AMC TOTP authentication. (CVE-2026-4114)

 - An improper handling of Unicode encoding vulnerability that allows a remote authenticated SSLVPN user to bypass Workplace/Connect Tunnel TOTP authentication. (CVE-2026-4116)

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

Solution
