Snort rule update for Sept. 2, 2021

Cisco Talos released the latest rule update for SNORTⓇ Thursday.

This release includes new protection against a critical vulnerability Cisco recently disclosed in its NFVIS software. There is a publicly available proof-of-concept exploit available for this vulnerability that could allow an attacker to bypass authentication and log in to a vulnerable device as an admin.

Here's a full breakdown of this rule update:
