Cisco Security Advisory

Cisco FireSIGHT System Software Convert Timing Channel Vulnerability

Medium

Advisory ID: cisco-sa-20160302-FireSIGHT1

Published: 2016 March 2 08:00 GMT

Version 1.0: Final

CVSS Score:

Base - 4.3

Workarounds:

No workarounds available

Cisco Bug IDs:

CSCuy41615

CVE-2016-1356

CWE-255

Summary

A vulnerability in credential authentication for valid and invalid 
username-password pairs for Cisco FireSIGHT System Software could allow an 
unauthenticated, remote attacker to determine a list of valid usernames for an
affected device.

The vulnerability is due to implementation details of how system credentials 
are verified by the affected software. An attacker could exploit this 
vulnerability by using a combination of valid system logins, invalid system 
logins, and time variability to try to continuously authenticate to a device.
An exploit could allow the attacker to obtain a list of valid system 
usernames. The list contains valid usernames only. The list does not contain 
any associated passwords.

Cisco has not released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
