IMAP Service STARTTLS Plaintext Command Injection

medium Nessus Plugin ID 52609

Synopsis

The remote mail service allows plaintext command injection while negotiating an encrypted communications channel.

Description

The remote IMAP service contains a software flaw in its STARTTLS implementation that could allow a remote, unauthenticated attacker to inject commands during the plaintext protocol phase that will be executed during the ciphertext protocol phase.

Successful exploitation could allow an attacker to steal a victim's email or associated SASL (Simple Authentication and Security Layer) credentials.

Solution

Contact the vendor to see if an update is available.
