Attackers exploit zero-days in consistently besieged SonicWall product
Brief
SonicWall customers are grappling with yet another pair of actively exploited zero-day vulnerabilities in SonicWall SMA 1000 appliances, a product that’s been besieged with recurring defects and attacks over the past nine months.
The vendor disclosed and released patches for the defects — CVE-2026-83548 and CVE-2026-83549 — and noted both were already actively exploited in the wild in a security advisory Tuesday. The Cybersecurity and Infrastructure Security Agency added the defects to its known exploited vulnerabilities (KEV) catalog Wednesday.
SonicWall customers have confronted a barrage of actively exploited vulnerabilities in SonicWall devices for years. Attackers have consistently exploited newly discovered zero-days and years-old defects in the vendor’s products to break into victim environments.
