Aiosmtpd · Aiosmtpd · 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.
