CVE-2024-34083

Name of the Vulnerable Software and Affected Versions aiosmtpd versions prior to 1.4.6

Description The issue concerns servers based on aiosmtpd, which 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.

Recommendations For versions prior to 1.4.6, update to version 1.4.6 to resolve the issue. As a temporary workaround, consider restricting the use of the STARTTLS command to minimize the risk of exploitation.
