SonicWall Releases Additional Update For SMA 100 Vulnerability
SonicWall has released a second firmware update for an SMA-100 zero-day vulnerability known to be used in attacks and is warning to install it immediately.
Last month, SonicWall disclosed that their internal systems were attacked using a zero-day vulnerability in their SMA-100 remote access devices.
A week later, cybersecurity firm NCC Group discovered the zero-day vulnerability used in this attack actively exploited in the wild.
On February 3rd, Sonicwall released a fix for the zero-day vulnerability and strongly recommended all users install it.
