| Re: [jetty-users] Website works but SSL Labs is reporting vulnerabilities |
Steve,
running stock jetty-9.3 in latest java8 gives me the following
protocols and ciphers:
[TLSv1, TLSv1.1, TLSv1.2]
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
TLS_RSA_WITH_AES_128_CBC_SHA256
TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA256
TLS_ECDH_RSA_WITH_AES_128_CBC_SHA256
TLS_DHE_RSA_WITH_AES_128_CBC_SHA256
TLS_DHE_DSS_WITH_AES_128_CBC_SHA256
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA
TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA
TLS_DHE_DSS_WITH_AES_128_CBC_SHA
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_RSA_WITH_AES_128_GCM_SHA256
TLS_ECDH_ECDSA_WITH_AES_128_GCM_SHA256
TLS_ECDH_RSA_WITH_AES_128_GCM_SHA256
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256
TLS_DHE_DSS_WITH_AES_128_GCM_SHA256
TLS_ECDHE_ECDSA_WITH_3DES_EDE_CBC_SHA
TLS_ECDH_ECDSA_WITH_3DES_EDE_CBC_SHA
SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA
TLS_ECDHE_ECDSA_WITH_RC4_128_SHA
TLS_ECDH_ECDSA_WITH_RC4_128_SHA
TLS_EMPTY_RENEGOTIATION_INFO_SCSV
Following the link on ssllabs shows that IE 8-10 will only speak
SSL3.0 or TLS1.0.... so TLS1.0 it will have to be. It has the
following ciphers:
TLS_RSA_WITH_AES_128_CBC_SHA (0x2f)128
TLS_RSA_WITH_AES_256_CBC_SHA (0x35)256
TLS_RSA_WITH_RC4_128_SHA (0x5) WEAK128
TLS_RSA_WITH_3DES_EDE_CBC_SHA (0xa)112
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (0xc013) Forward Secrecy128
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (0xc014) Forward Secrecy256
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA (0xc009) Forward Secrecy128
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA (0xc00a) Forward Secrecy256
TLS_DHE_DSS_WITH_AES_128_CBC_SHA (0x32) Forward Secrecy2128
TLS_DHE_DSS_WITH_AES_256_CBC_SHA (0x38) Forward Secrecy2256
TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA (0x13) Forward Secrecy2112
TLS_RSA_WITH_RC4_128_MD5 (0x4) WEAK
So there are indeed no ciphers in common!
You would think that TLS_RSA_WITH_AES_256_CBC_SHA (0x35)256 should be
acceptable to the server as it does accept
TLS_RSA_WITH_AES_128_CBC_SHA256 ?
Let me investigate why that is not being offered....
