CVE-2020-12619 (GCVE-0-2020-12619)

Vulnerability from cvelistv5 – Published: 2020-08-20 22:44 – Updated: 2024-08-04 12:04

Summary

MailMate before 1.11 automatically imported S/MIME certificates and thereby silently replaced existing ones. This allowed a man-in-the-middle attacker to obtain an email-validated S/MIME certificate from a trusted CA and replace the public key of the entity to be impersonated. This enabled the attacker to decipher further communication. The entire attack could be accomplished by sending a single email.

Severity

No CVSS data available.
