Nginx 0.7.22 < 1.29.1 Buffer Over-read

Synopsis

Nginx 0.7.22 < 1.29.1 Buffer Over-read

Description

According to its Server response header, the installed version of nginx is from 0.7.22 to 1.29.0. It is, therefore, affected by a buffer over-read vulnerability in the ngx_mail_smtp_module that might allow an unauthenticated attacker to over-read NGINX SMTP authentication process memory; as a result, the server side may leak arbitrary bytes sent in a request to the authentication server.

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 1.29.1 or later.
