Name of the Vulnerable Software and Affected Versions: Cisco products (affected versions not specified)

Description: The issue is related to an incorrect connection count comparison in the rate filtering feature of the Snort detection engine. This could allow an unauthenticated, remote attacker to bypass a configured rate limiting filter by sending traffic through an affected device at a rate that exceeds a configured rate filter. A successful exploit could allow the attacker to successfully bypass the rate filter, potentially allowing unintended traffic to enter the network protected by the affected device.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
