Risk 55
Severity

AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:L

A vulnerability exists in the ngxhttpscgimodule and ngxhttpuwsgimodule modules that may result in excessive memory allocation or an over-read of data. When scgipass or uwsgipass is configured, an unauthenticated attacker with man-in-the-middle (MITM) ability to control responses from an upstream server may be able to read the memory of the NGINX worker process or restart it.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
