SMA100 SSL-VPN OS Command Injection Vulnerability
Actively exploited in the wild. Patch or mitigate immediately — don't wait for a maintenance window.
An attacker with administrative privileges, remotely over the network, with no user interaction, can fully compromise the system — steal data, tamper with it and take it offline.
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.

Generated by Wavense from the CVE record — an immediate mitigation and the permanent fix.
Immediately restrict network access to the SMA100 SSL-VPN management interface to only trusted administrative IP ranges. Implement strong, unique passwords and enable Multi-Factor Authentication (MFA) for all administrative accounts if supported. Enhance monitoring for suspicious login attempts or unusual command execution patterns on the VPN appliance.
The permanent resolution is to apply the vendor-provided security patches as soon as they become available. Upgrade the SMA100 SSL-VPN firmware to the latest secure version specifically addressing CVE-2023-44221. Ensure all instances are updated to prevent exploitation of this critical vulnerability.
A remote authenticated attacker with administrative privileges can inject arbitrary OS commands on the SMA100 SSL-VPN management interface. This allows for execution of malicious code as the 'nobody' user, potentially leading to system compromise, data exfiltration, or denial of service. The successful exploitation could severely impact the confidentiality, integrity, and availability of connected resources.
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.
