1) Man-in-the-Middle (MitM) attack (CVE-ID: CVE-2020-14093)

CWE-ID: CWE-300 - Channel Accessible by Non-Endpoint ('Man-in-the-Middle')

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to perform a Man-in-the-Middle (MitM) attack.

The vulnerability exists within the IMAP fcc/postpone when processing PREAUTH responses. A remote attacker with ability to intercept traffic can perform a Man-in-the-Middle (MitM) attack.


2) Code injection (CVE-ID: CVE-2020-14954)

CWE-ID: CWE-74 - Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/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 spoofing attack.
