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.
CERT Bulgaria encourages users and
administrators to review the SonicWall security
advisory and apply the necessary firmware updates as soon as possible.
