SonicWall Warns of Actively Exploited Vulnerabilities in SMA1000 Appliances
Two remotely exploitable zero-day vulnerabilities in SonicWall SMA1000 appliances are being chained together to achieve remote code execution, according to a recent SonicWall security alert. SMA1000 appliances are used for secure remote access and VPN connections and, as such, are commonly exposed to the Internet. One of the vulnerabilities, tracked as CVE-2026-83548, is a critical pre-authentication server-side request forgery issue in the Appliance Work Place interface that allows command injection. The vulnerability has been assigned a maximum CVSS v 3.1 severity score of 10. Successful exploitation allows a remote attacker to access sensitive functions and perform unauthorized actions. The vulnerability is being chained with an exploit for a high-severity (CVSS v3.1: 7.8) OS command injection vulnerability – CVE-2026-83549 – in the Appliance Management Console. Attackers with admin privileges can exploit the vulnerability and execute OS commands. The vulnerability is due to improper neutralization of special elements used in an OS command. The SonicWall PSIRT has...
