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. This issue has been addressed in version 1.4.5. Users are advised to upgrade. There are no known workarounds for this vulnerability."}, {"lang": "es", "value": "aiosmtpd es una reimplementaci\u00f3n de Python stdlib smtpd.py basada en asyncio. aiosmtpd es vulnerable al contrabando SMTP entrante.

Al explotar el contrabando SMTP, un atacante puede enviar correos electr\u00f3nicos de contrabando/falsificaci\u00f3n con direcciones de remitente falsas, lo que permite ataques de phishing avanzados. Este problema tambi\u00e9n existe en otro software SMTP como Postfix.
