high Nessus Plugin ID 71117

Synopsis

The remote web server is affected by a security bypass vulnerability.

Description

According to the self-reported version in the Server response header, the installed version of nginx is greater than 0.8.41 but prior to 1.4.4 / 1.5.7. It is, therefore, affected by a security bypass vulnerability in 'ngx_http_parse.c' when a file with a space at the end of the URI is requested.
