Kerentanan Allocation of Resources Without Limits or Throttling. Skor CVSS 3.1 5.3 (Medium) menurut vulncheck.com.

Deskripsi (NVD)

Tornado before 6.5.9 fails to limit the number of query string fields in HTTPServerRequest.__init__, allowing remote attackers to cause event-loop stalling by sending requests with thousands of query parameters. Attackers can send unauthenticated GET requests with unbounded query-string field counts to degrade response times for all clients sharing the same IOLoop.
