Vigil@nce - nginx: injection of SMTP commands though an SSL tunnel

August 2014 by Vigil@nce

This bulletin was written by Vigil@nce : http://vigilance.fr/offer

SYNTHESIS OF THE VULNERABILITY

An attacker who is able to capture and inject network traffic can insert SMTP commands into the nginx ’s proxy, for instance in order to retrieve secret data.

Impacted products: nginx

Severity: 1/4

Creation date: 06/08/2014

DESCRIPTION OF THE VULNERABILITY

The nginx product offers a SMTP proxy.

The SMTP command STARTTLS is used to insert a SSL tunnel between the TCP connection and the SMTP connection. However, nginx does not rightly reset buffers of exchanged data when it process this command.

An attacker who is able to capture and inject network traffic can therefore insert SMTP commands into the nginx ’s proxy, for instance in order to retrieve secret data.
