Description
This security bulletin contains information about 1 vulnerability.
1) Man-in-the-Middle (MitM) attack (CVE-ID: CVE-2020-14002)
CWE-ID: CWE-300 - Channel Accessible by Non-Endpoint ('Man-in-the-Middle')
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a Man-in-the-Middle (MitM) attack.
The vulnerability exists due to an observable discrepancy issue 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).
