SonicWall PSIRT ([email protected] CNA) via NVD
SonicWall is its own CVE Numbering Authority. Its PSIRT portal (psirt.global.sonicwall.com) is a reCAPTCHA-gated JavaScript app with no stable public feed, so VulniPulse ingests SonicWall's CVEs from the NVD CNA feed ([email protected]), grouped by the official SNWLID advisory, with affected products and versions from each description and a link back to the SNWLID advisory. Covers SonicOS firewalls (Gen6/Gen7 TZ/NSa/NSsp/NSv), Secure Mobile Access (SMA 100/1000), SSL-VPN, NetExtender, Email Security and GMS/Analytics — SonicWall SSL-VPN is a frequent ransomware entry point.
