IBM Storwize SSL/TLS RC4 Stream Cipher Key Invariance (Bar Mitzvah)

Medium Nessus Plugin ID 91633


The remote host is affected by a security feature bypass vulnerability.


According 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.


Upgrade to IBM Storwize version / / / or later.
