UPDATE. A critical security bug in the SonicWall VPN portal can be used to crash the device and prevent users from connecting to corporate resources.
"The most notable aspect of this vulnerability is that the VPN portal can be exploited without knowing a username or password," Young told Threatpost.
SonicWall has issued a patch; SSL VPN portals may be disconnected from the internet as a temporary mitigation before the patch is applied.
CVE-2020-5142 allows an unauthenticated attacker to inject JavaScript code in the firewall SSL-VPN portal.
Several vulnerabilities open a path to DoS attacks and can be used even by an unauthenticated attacker.
