The version of Java SDK installed on the remote host is affected by multiple vulnerabilities :
A man-in-the-middle information disclosure vulnerability exists due to a TLS security downgrade flaw. A man-in-the-middle attacker may be able to downgrade the SSL/TLS connection to use EXPORT_RSA cipher suites which can be factored in a short amount of time, allowing the attacker to intercept and decrypt the traffic.
(CVE-2015-0138)
A flaw exists in the RC4 algorithm implementation due to improper combination of state data with key data during the initialization phase. A man-in-the-middle attacker can exploit this to conduct plaintext-recovery attacks.
(CVE-2015-2808)
