SonicWall SMA100 Command Injection DoS Vulnerability
Actively exploited in the wild. Patch or mitigate immediately — don't wait for a maintenance window.
An attacker with a basic user account, remotely over the network, with no user interaction, can take the system offline.
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.

Generated by Wavense from the CVE record — an immediate mitigation and the permanent fix.
Implement strict network access controls to limit connectivity to the SMA100 management interface only from trusted IP addresses or management networks. Enable and monitor logs for suspicious command execution attempts, unauthorized access, or unusual activity patterns on the SMA100 appliance. Ensure strong, unique credentials are used for all administrative accounts and consider enabling multi-factor authentication for management access if supported.
The permanent resolution involves upgrading the SonicWall SMA100 series appliances to the patched firmware versions provided by the vendor. Specifically, SMA 200/210/400/410 devices should be updated to firmware 10.2.1.2-24sv or later, and SMA 500v devices to 10.2.1.2-24sv or later. Consult official SonicWall security advisories and support documentation for precise upgrade paths and instructions to ensure complete remediation.
A remote authenticated attacker can exploit this vulnerability to inject arbitrary commands on the SMA100 management interface, operating with the privileges of a 'nobody' user. This command injection can lead to a Denial of Service (DoS) condition, rendering the SMA100 appliance inaccessible and disrupting critical remote access for users. The inability to access or manage the device can severely impact business operations reliant on the SMA100, causing significant downtime and productivity loss.
Other CVEs affecting sma 200 firmware
A Stack-based buffer overflow vulnerability in SMA100 Apache httpd server's mod_cgi module environment variables allows a remote unauthenticated attacker to potentially execute code as a 'nobody' user in the appliance. This vulnerability affected SMA 200, 210, 400, 410 and 500v appliances firmware 10.2.0.8-37sv, 10.2.1.1-19sv, 10.2.1.2-24sv and earlier versions.
Improper neutralization of a SQL Command leading to SQL Injection vulnerability impacting end-of-life Secure Remote Access (SRA) products, specifically the SRA appliances running all 8.x firmware and 9.0.0.9-26sv or earlier
A SQL-Injection vulnerability in the SonicWall SSLVPN SMA100 product allows a remote unauthenticated attacker to perform SQL query to access username password and other session related information. This vulnerability impacts SMA100 build version 10.x.
Improper escaping of output in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to map URLs to filesystem locations that are permitted to be served by the server but are not intentionally/directly reachable by any URL, resulting in code execution or source code disclosure. Substitutions in server context that use a backreferences or variables as the first segment of the substitution are affected. Some unsafe RewiteRules will be broken by this change and the rewrite flag "UnsafePrefixStat" can be used to opt back in once ensuring the substitution is appropriately constrained.
Improper neutralization of special elements in the SMA100 SSL-VPN management interface allows a remote authenticated attacker with administrative privilege to inject arbitrary commands as a 'nobody' user, potentially leading to OS Command Injection Vulnerability.
