An issue was discovered in CipherMail Community Gateway Virtual Appliances and Professional/Enterprise Gateway Virtual Appliances versions 1.0.1 through 4.7.1-0 and CipherMail Webmail Messenger Virtual Appliances 1.1.1 through 3.1.1-0. A Diffie-Hellman parameter of insufficient size could allow man-in-the-middle compromise of communications between CipherMail products and external SMTP clients.
The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
