Vigil@nce - Zend Framework: header injection via CRLF

July 2015 by Vigil@nce

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

SYNTHESIS OF THE VULNERABILITY

An attacker can inject line feeds in the Zend\Mail and Zend\Http modules of Zend Framework, in order to modify the content of generated messages/queries.

Impacted products: Debian, Fedora, Zend Framework

Severity: 2/4

Creation date: 11/05/2015

DESCRIPTION OF THE VULNERABILITY

The Zend Framework provides the Zend\Mail and Zend\Http modules in order to generate mails or web queries.

For example, the Zend\Mail\Message::setSubject() method defines the subject of the mail. However, a user who can alter the subject can insert line feeds and thus inject new headers to modify the mail content.

The Zend\Http class is impacted by a similar vulnerability.

An attacker can therefore inject line feeds in the Zend\Mail and Zend\Http modules of Zend Framework, in order to modify the content of generated messages/queries.
