Exim mail server: Vulnerabilities

1 min read

Researchers at safety firm Qualys found 21 vulnerabilities in Exim, a preferred mail server, which will be chained to acquire “a full distant unauthenticated code execution and achieve root privileges on the Exim Server.”.

Exim is a mail switch agent (MTA), liable for receiving and forwarding electronic mail messages. It runs totally on Unix or Linux and can also be the principle MTA used on cPanel.

In keeping with one current survey almost 60 per cent of mail servers seen on the web use Exim.

The Qualys researchers have now reported on 21 vital vulnerabilities found through a code audit, 10 of which will be exploited remotely.

Profitable exploitation of those vulnerabilities would permit a distant attacker to realize full root privileges on the goal server and execute instructions to put in applications, modify knowledge, and create new accounts.

All variations earlier than Exim-4.94.2 are weak, and safety updates had been launched for the vulnerabilities on 04/05/2021.

We might strongly advise all shoppers operating exim to use the updates for this as quickly as doable.

For patrons operating cPanel, so long as you’ve utilized all updates out there, this could then be utilizing the newest model of Exim that’s not weak.
