Security Bulletin


Summary

The RC4 “Bar Mitzvah” Attack for SSL/TLS affects OpenSSL. OpenSSL is used by IBM InfoSphere Master Data Management. IBM InfoSphere Master Data Management has addressed the applicable CVEs.

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)
