Sonicwall Management Vulnerability
-
SonicWall physical firewall appliances running certain versions of SonicOS contain vulnerabilities in code utilized for remote management. At this time, there is no indication that the discovered vulnerabilities are being exploited in the wild, however:
SonicWall STRONGLY advises to apply the SonicOS patch immediately.
IF you cannot update immediately, as a mitigation please restrict SonicWall management access (HTTPS/HTTP/SSH) to trusted sources and/or disable management access from untrusted Internet sources, then apply the SonicOS patch as soon as possible.
Note: SonicWall will communicate any future updates via this Security Advisory and SonicWall PSIRT Advisory SNWLID-2019-0009.
