  • Boolean-based blind SQLi detection: send two POST requests to /scgi-bin/platform.cgi with differing Domainname payloads (false condition vs. true condition) and compare responses — false condition yields 'User authentication Failed', true condition yields 'User Login Failed for SSLVPN User.'
  • The SQL injection is injected via the USERDBDomains.Domainname POST parameter at the /scgi-bin/platform.cgi endpoint using a boolean AND-based payload appended to the domain value (e.g., geardomain' AND '5434'='5434).
  • Content-Type header used in the exploit POST request is application/x-www-form-urlencoded; charset=utf-8 — filter/alert on POST requests to /scgi-bin/platform.cgi with this content type containing SQL metacharacters in Domainname.
  • ·The vulnerable endpoint path in the NVD description is listed as cgi-bin/platform.cgi, but the actual exploit template targets /scgi-bin/platform.cgi — detection rules should cover both paths.
  • ·Affected firmware versions include FVS336Gv2 and FVS336Gv3; the Nuclei template CPE references ssl312_firmware/fvs336gv2 — ensure asset inventory covers both hardware revisions.
