SonicWall has released a security advisory to address vulnerabilities affecting SonicWall Secure Mobile Access (SMA) 100 series appliances. A remote attacker could exploit these vulnerabilities to take control of an affected system. SMA 100 series appliances provide an organization’s employees with remote access to internal resources. Note: although there are currently no reports of these vulnerabilities being exploited in the wild, in July 2021, CISA warned of threat actors actively targeting a known, previously patched, vulnerability in SonicWall SMA 100 series appliances.
CISA encourages users and administrators to review the SonicWall security advisory and apply the necessary firmware updates as soon as possible.
