Critical SonicWall vulnerabilities "extremely attractive" - central firewall hub needs urgent patching
Multiple critical unauthenticated SQL injection bugs and hard-coded credentials as well as command injection, and file upload bugs need urgent patching.
The SonicWall GMS – a software application used to centrally manage SonicWall firewall appliances and security policy configurations – has numerous vulnerabilities that demand urgent patching, including multiple critical unauthenticated SQL injection bugs and hard-coded credentials.
The 15 SonicWall vulnerabilities were reported to the security company by NCC Group via the Zero Day Initiative (ZDI) under what appears to have been a robust security audit, and are not yet being exploited in the wild.
SonicWall vulnerabilities have previously been widely exploited however (CVE-2021-20038 was among 2021’s most exploited vulnerabilities for example) and security researchers say they expect the SonicWall vulnerabilities to be “be extremely attractive to adversaries – including those looking to extort victims after executing smash-and-grab attacks.”

Security appliances sitting at the edge of networks are ripe targets for attack and vulnerabilities in them are often then used to piggyback further into corporate infrastructure before deploying ransomware.
The 15 SonicWall vulnerabilities also include a hard-coded Tomcat credentials issue, command injection, and file upload bugs. They affect GMS - Virtual Appliance 9.3.2-SP1 and earlier versions; GMS - Windows 9.3.2-SP1 and earlier versions; Analytics - 2.5.0.4-R7 and earlier versions.
They were all reported by Richard Warren and Sean Morland of NCC Group, with two also reported by Alex Birnberg of Zymo Security. There is no workaround available for this suite of SonicWall vulnerabilities. The Stack would expect threat actors and other offensive security researchers to be rapidly reverse engineering the patches and POCs to land soon.
