CVE-2016-0772

Disclosure Date: September 02, 2016 •
CVE-2016-0772 CVSS v3 Base Score: 6.5
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

The smtplib library in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 does not return an error when StartTLS fails, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a “StartTLS stripping attack.”
