So from what I can gather, there are 2 issues:
1. Testing for the vulnerability.
2. Resolving the vulnerability.
For testing, there you may install OpenSSL on your local machine and try "openssl s_client -connect [host]:[sslport] -cipher LOW"
Aside from installing OpenSSL, there are various web-based resources that you can use as well.
For resolving the vulnerability, that is specific to the vulnerabile software. That being said, here's a good article in this regard.
Hope this helps,
