InterScan Web Security Virtual Appliance (IWSVA) 6.5 Service Pack 2 (SP2) does not support SSL RC4 Cipher Suites. Fixing SSL Certificate Chain Contains RSA Keys Less Than 2048 bits. Description The remote host supports the use of RC4 in one or more cipher suites. Unfortunately this turned up several errors, all of them had to do with Secure Sockets Layer or SSL which in Microsoft Windows Server 2003 / Internet Information Server 6 out of the box support both unsecure protocols and cipher suites. Nessus regards medium strength as any encryption that uses key lengths at least 64 bits and less than 112 bits, or else that … Multiple vulnerabilities have been found in SSL’s RC4 implementation: * The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext. Clients and servers that do not want to use RC4 regardless of the other party’s supported ciphers can disable RC4 cipher suites completely by setting the following registry keys. In this manner, any server or client that is talking to a client or server that must use RC4 can prevent a connection from occurring. 65821 - SSL RC4 Cipher Suites Supported (Bar Mitzvah) List of RC4 cipher suites supported by the remote server : ECDHE-RSA-RC4-SHA Kx=ECDH Au=RSA Enc=RC4(128) Mac=SHA1 RC4-MD5 Kx=RSA Au=RSA Enc=RC4(128) Mac=MD5 RC4-SHA Kx=RSA Au=RSA Enc=RC4(128) Mac=SHA1 . Beyond Security did not participate in this race to mutually assured destruction of the industry and to this day produces the most accurate and actionable reports available. If RC4 must remain enabled, the RC4 cipher suite should be placed at the end of the list of cipher suites. The TLS server MAY send the insufficient_security fatal alert in this case.
