Vulnerability Details CVEID:CVE-2015-2808 DESCRIPTION:The RC4 algorithm, as used in the TLS protocol and SSL protocol, could allow a remote attacker to obtain sensitive information. An attacker could exploit this vulnerability to remotely expose account credentials without requiring an active man-in-the-middle session. Successful exploitation could allow an attacker to retrieve credit card data or other sensitive information. This vulnerability is commonly referred to as "Bar Mitzvah Attack". CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101851 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N) Affected Products and Versions IBM Netezza Platform Software 22.214.171.124-P1 and earlier (all 7.0.4 releases) IBM Netezza Platform Software 126.96.36.199-P1 and earlier (all 7.0.2 releases) Unaffected Products and Versions IBM Netezza Platform Software 7.1 and later (all 7.1 releases) IBM Netezza Platform Software 7.2 and later (all 7.2 releases) Remediation/Fixes Product VRMF APAR Remediation/First Fix IBM Netezza Platform Software 188.8.131.52-P2 Link to IBM Fix Central IBM Netezza Platform Software 184.108.40.206-P2 Link to IBM Fix Central You should verify applying this fix does not cause any compatibility issues. The fix disables RC4 stream cipher by default. If you change this setting you will expose yourself to the attack described above. IBM recommends that you review your entire environment to identify other areas where you have enabled the RC4 stream cipher and take appropriate mitigation and remediation actions. For all 7.0.0 and 6.0.8 IBM Netezza Platform Software releases, IBM recommends upgrading to a fixed, supported version/release/platform of the product.
