CVE-2020-14145

Disclosure Date: June 29, 2020
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected.
