aiosmptd is a reimplementation of the Python stdlib smtpd.py based on asyncio. Prior to version 1.4.6, servers based on aiosmtpd accept extra unencrypted commands after STARTTLS, treating them as if they came from inside the encrypted connection. This could be exploited by a man-in-the-middle attack. Version 1.4.6 contains a patch for the issue. aiosmptd es una reimplementación de Python stdlib smtpd.py basada en asyncio.

aiosmtpd is a reimplementation of the Python stdlib smtpd.py based on asyncio. aiosmtpd is vulnerable to inbound SMTP smuggling. SMTP smuggling is a novel vulnerability based on not so novel interpretation differences of the SMTP protocol. By exploiting SMTP smuggling, an attacker may send smuggle/spoof e-mails with fake sender addresses, allowing advanced phishing attacks. This issue is also existed in other SMTP software like Postfix. With the right SMTP server constellation, an attacker can send spoofed e-mails to inbound/receiving aiosmtpd instances. • https://github.com/aio-libs/aiosmtpd/commit/24b6c79c8921cf1800e27ca144f4f37023982bbb https://github.com/aio-libs/aiosmtpd/security/advisories/GHSA-pr2m-px7j-xg65 https://www.postfix.org/smtp-smuggling.html • CWE-345: Insufficient Verification of Data Authenticity •
