Summary

The RC4 “Bar Mitzvah” Attack for SSL/TLS affects IBM Security Network Intrusion Prevention System.

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”.
