Improper Verification of Cryptographic Signature in Mozilla Thunderbird - CVE-2022-2226

Published: June 29, 2022


Vulnerability identifier: #VU64769
CSH Severity: Low
CVSS v4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]
CVE-ID: CVE-2022-2226
CWE-ID: CWE-347
Exploitation vector: Remote access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to improper validation of digital signatures. When displaying an email that contains a digital signature, the email's date will be shown. If the dates were different, then Thunderbird didn't report the email as having an invalid signature. If an attacker performed a replay attack, in which an old email with old contents are resent at a later time, it could lead the victim to believe that the statements in the email are current.
