CVE-2011-4968 nginx: http proxy module does not validate SSL certificates
It was reported [1],[2] that nginx does not verify the identity of an origin server when the http proxy module talks to that origin server over HTTPS. This could allow for a MITM attack between the proxy and the origin server.
There are proposed patches attached to the upstream ticket, but as of yet this is not fixed in any release.
