CISA Warns of SonicWall SMA1000 Vulnerabilities Active Exploitation (CVE-2026-83548 & CVE-2026-83549)

CISA added two actively exploited SonicWall SMA1000 flaws to KEV: pre-auth SSRF CVE-2026-83548 (CVSS 10) and post-auth RCE CVE-2026-83549; patch by September 5.

CISA added CVE-2026-83548 and CVE-2026-83549 to the Known Exploited Vulnerabilities Catalog with a September 5, 2026 patch deadline. CVE-2026-83548 is a critical (CVSS 10.0) pre-authentication SSRF in the SMA1000 Appliance Work Place interface; CVE-2026-83549 is a high (CVSS 7.8) post-authentication OS command injection leading to RCE in the Appliance Management Console. SMA1000 models 6210, 7210, and 8200v running 12.4.3-03453 or 12.5.0-02835 platform-hotfix and older are affected; fixes ship in 12.4.3-03526 and 12.5.0-02952.

    Pre-Authentication SSRF in SonicWall SMA1000 Appliance Workplace Interface
    CVE-2026-83548 is a critical (CVSS 3.1 score 10.0) server-side request forgery (SSRF) vulnerability in the Workplace interface of SonicWall SMA1000 appliances, caused by an unintended alternate access path (unprotected alternate channel, CWE-441; SSRF, CWE-918). Because it is pre-authentication, any remote unauthenticated attacker who can reach the interface can trigger it and gain unauthorized access to sensitive functionality and perform unauthorized operations. CISA lists all SonicWall SMA1000 appliances as affected, with CPE data naming the SMA 8200v and SMA 6210/7210 firmware; internet-exposed units are at highest risk. The flaw is being actively exploited in the wild: it was added to CISA's Known Exploited Vulnerabilities catalog on 2026-09-02 alongside companion zero-day CVE-2026-83549, which reporting suggests may form an attack chain with this SSRF. Exploitation probability is elevated (EPSS 4.7%, 91st percentile) and no public proof-of-concept is known.

    Authenticated OS Command Injection RCE in SonicWall SMA1000 Appliance Console
    CVE-2026-83549 is a post-authentication OS command injection flaw (CWE-78) in the Appliance Management Console (AMC) of SonicWall SMA1000 appliances. An attacker who authenticates to the AMC with administrator privileges can, under specific conditions, inject arbitrary operating system commands and achieve remote code execution on the appliance. Only organizations running SMA1000-series appliances, including the SMA 6210, SMA 7210, and SMA 8200v models cited in the data, are affected. CISA added the flaw to the KEV catalog on 2026-09-02, and news reports describe active exploitation, possibly chained with companion zero-day CVE-2026-83548, with reverse shells and cryptocurrency miners observed; no public proof-of-concept is known. EPSS assigns an 8.5% probability of exploitation within 30 days (95th percentile).
