IBM Storwize SSL/TLS RC4 Stream Cipher Key Invariance (Bar Mitzvah)
Low Nessus Plugin ID 91633
SynopsisThe remote host is affected by a security feature bypass vulnerability.
DescriptionAccording to its self-reported version number, the IBM Storwize server running on the remote host is affected by a security feature bypass vulnerability, known as Bar Mitzvah, due to improper combination of state data with key data by the RC4 cipher algorithm during the initialization phase. A man-in-the-middle attacker can exploit this, via a brute-force attack using LSB values, to decrypt the traffic.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to IBM Storwize version 184.108.40.206 / 220.127.116.11 / 18.104.22.168 / or later.
