GHSA-6QP5-C345-G9C7

Vulnerability from github – Published: 2022-05-24 17:26 – Updated: 2022-05-24 17:26

Details

eM Client before 7.2.33412.0 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.
