Running Splunk Enterprise Version: 7.2.0 Build: 8c86330ac18 on Windows Server 2012R2.
Ran Nessus Professional Version 8.0.1 (#155) WINDOWS scan and received this low risk finding:
OpenSSL AES-NI Padding Oracle MitM Information Disclosure
"It was possible to obtain sensitive information from the remote host
with TLS-enabled services."
"The remote host is affected by a man-in-the-middle (MitM) information
disclosure vulnerability due to an error in the implementation of
ciphersuites that use AES in CBC mode with HMAC-SHA1 or HMAC-SHA256.
The implementation is specially written to use the AES acceleration
available in x86/amd64 processors (AES-NI). The error messages
returned by the server allow allow a man-in-the-middle attacker to
conduct a padding oracle attack, resulting in the ability to decrypt
network traffic."
Upgrade to OpenSSL version 1.0.1t / 1.0.2h or later.
Checked OpenSSL version like this:
E:\Splunk\bin>splunk cmd openssl version
OpenSSL 1.0.2o-fips 27 Mar 2018
If I'm already using OpenSSL 1.0.2o-fips why is the vulnerability still there?
I should add that this is CVE-2016-2107.
