"The remote NewStart CGSL host, running version MAIN 4.06, has openssl packages installed that are affected by a
vulnerability:
- If an application encounters a fatal protocol error and
then calls SSL_shutdown() twice (once to send a
close_notify, and once to receive one) then OpenSSL can
respond differently to the calling application if a 0
byte record is received with invalid padding compared to
if a 0 byte record is received with an invalid MAC. If
the application then behaves differently based on that
in a way that is detectable to the remote peer, then
this amounts to a padding oracle that could be used to
decrypt data. In order for this to be exploitable non-
stitched ciphersuites must be in use. Stitched
ciphersuites are optimised implementations of certain
commonly used ciphersuites. Also the application must
call SSL_shutdown() twice even if a protocol error has
occurred (applications should not do this but some do
anyway). Fixed in OpenSSL 1.0.2r (Affected
1.0.2-1.0.2q). (CVE-2019-1559)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
