Summary

The RC4 “Bar Mitzvah” Attack for SSL/TLS affects Rational Automation Framework.

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&gt;for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)
