Not answering your original question. But you can test it using one
of the following tools:
The following tools have checks that will cover ROBOT:
testssl.sh has a test closely modelled after our own one. A snapshot
is available, it's not yet part of a release. It also supports SNI and
STARTTLS, which our test does not.
TLS-Attacker already contained Bleichenbacher checks before our
research, version 2.2 was extended with additional checks to cover all
SSLLabs has added a check in their development version.
Tripwire IP360 added detection for vulnerable F5 devices in ASPL-753
which was released in coordination with F5's public advisory. Generic
detection of Bleichenbacher oracles will be released in coordination
with this publication.
tlsfuzzer has an extensive test script for Bleichenbacher vulns,
though it will also complain about misbehaving servers that are not
SSLyze added support for ROBOT detection after our disclosure.
