SonicWall Secure Mobile Access DoS (SNWLID-2021-0022)

medium Nessus Plugin ID 235817

Synopsis

The remote host is missing a security update.

Description

The version of SonicWall Secure Mobile Access installed on the remote host is prior to 9.0.0.11-31sv, or 10.2.1 prior to 10.2.1.1-19sv. It is, therefore, affected by a vulnerability as referenced in the SNWLID-2021-0022 advisory:

 - Improper neutralization of special elements in the SMA100 management interface allows a remote authenticated attacker to inject arbitrary commands as a 'nobody' user which potentially leads to DoS. (CVE-2021-20035)

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

Solution

Upgrade SonicWall Secure Mobile Access version 9.0.0.11-31sv, 10.2.0.8-37sv, 10.2.1.1-19sv or later.
