Synopsis

Nginx 1.x < 1.14.1 Multiple Vulnerabilties

Description

According to its Server response header, the installed version of nginx is 1.x prior to 1.14.1 or 1.15.x prior to 1.15.6. It is, therefore, affected by the following issues :

 - An unspecified error exists related to the module 'ngx_http_v2_module' that allows excessive memory usage. (CVE-2018-16843)

 - An unspecified error exists related to the module 'ngx_http_v2_module' that allows excessive CPU usage. (CVE-2018-16844)

 - An unspecified error exists related to the module 'ngx_http_mp4_module' that allows worker process crashes or memory disclosure. (CVE-2018-16845)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to nginx version 1.14.1 or later.
