DESCRIPTION:
A vulnerability has been reported in Ipswitch IMail Server, which can
be exploited by malicious people to manipulate certain data.
The vulnerability is caused due to the TLS implementation not
properly clearing transport layer buffers when upgrading from
plaintext to ciphertext after receiving the "STARTTLS" command. This
can be exploited to insert arbitrary plaintext data (e.g. SMTP
commands) during the plaintext phase, which will then be executed
after upgrading to the TLS ciphertext phase.
SOLUTION:
Reportedly, the vendor will fix this in an upcoming version.
