HI, Our customer uses XOS 220.127.116.11 patch 1.8 and during the test he found out that SSL 3.0 is an obsolete and insecure protocol. Encryption in SSL 3.0 uses either the RC4 stream cipher, or a block cipher in CBC mode. RC4 is known to have biases, and the block cipher in CBC mode is vulnerable to the POODLE attack.
The SSLv3 protocol is insecure due to the POODLE attack and the weakness of RC4 cipher.
. Extreme page says about poodle that XOS version higher than 15.3 is patched , however SSL v3 is stil availble there , am i right ? How to deactiavte SSLv3 on this version and use TLS 1.1 or higher ?
Can you elabore more on SSLv3 ?A. Dembiczak
