The remote service accepts connections encrypted using SSL 2.0 and/or SSL 3.0.
These versions of SSL are affected by several cryptographic flaws.
An attacker can exploit these flaws to conduct man-in-the-middle attacks or to decrypt communications
between the affected service and clients. NIST has determined that SSL 3.0 is no longer acceptable
for secure communications. As of the date of enforcement found in PCI DSS v3.1, any version of SSL
will not meet the PCI SSC'S definition of 'strong cryptography'.
Solution
Consult the application's documentation to disable SSL 2.0 and 3.0. Use TLS 1.1 (with approved cipher suites) or higher instead.
