The remote host stores local confidential data in an insecure manner.
The remote host is running Ipswitch IMail, an e-mail server that serves email via a web interface. IMail runs on Microsoft Windows operating systems. Ipswitch IMail is reported to use a weak encryption algorithm when obfuscating saved passwords. A local attacker who has the ability to read the encrypted passwords from the system registry may easily derive the plaintext password if the username that is associated with the password is known.
Upgrade or patch according to vendor recommendations.
