STARTTLS plaintext command injection vulnerability

Overview

Some STARTTLS implementations could allow a remote attacker to inject commands during the plaintext phase of the protocol.

Description

STARTTLS is an extension to plaintext communication protocols that offers a way to upgrade a plaintext connection to an encrypted (TLS or SSL) connection instead of using a separate port for encrypted communication. Some implementations of STARTTLS contain a vulnerability that could allow a remote unauthenticated attacker to inject commands during the plaintext protocol phase, that will be executed during the ciphertext protocol phase. This vulnerability is caused by the switch from plaintext to TLS being implemented below the application’s I/O buffering layer.

This issue is only of practical concern for affected implementations that also perform correct certificate validation. Implementations which do not perform certificate validation are already inherently vulnerable to man-in-the-middle attacks.

Note: Not all implementations of STARTTLS are affected by this vulnerability. Some implementations of Simple Authentication and Security Layer (SASL) could also be affected by this vulnerability. Please see the Vendor Information below for specific vendor information.

---

Impact

A remote attacker with the ability to pose as a man-in-the-middle may be able to inject commands for the corresponding protocol (e.g., SMTP, POP3, etc.) during the plaintext protocol phase, that will then be executed during the ciphertext protocol phase.

---

Solution

Update

Please see the Vendor Information below for specific vendor information and patches.

---

Purge the application I/O buffer

Developers of STARTTLS-enabled applications should take care to purge the application’s I/O buffer immediately after switching to TLS in order to mitigate this vulnerability.

Red Hat, Inc. __ Affected

Notified: January 19, 2011 Updated: April 07, 2011

Status

Affected

Vendor Statement

Vulnerable. This issue affects postfix packages in Red Hat Enterprise

Linux 4, 5, and 6. The Red Hat Security Response Team has rated this
issue as having moderate security impact, a future update will address

SMTP over TLS replaces the entire received SMTP commands stream, along
with its read/write buffers and read/write functions.

This issue did not affect the versions of the exim package as shipped
with Red Hat Enterprise Linux 4 and 5, as Exim by switching to SMTP over
TLS replaces plaintext read/write functions with TLS read/write functions.
