Weekly Snort rule update for Feb. 14 - 18

Cisco Talos released two new rule sets for SNORTⓇ this week, which you can view here and here.

Our two releases include several new protections against a variety of malicious webshells. There is also an additional rule that protects against the string of vulnerabilities Cisco recently disclosed in its RV series of routers aimed at small businesses.

The CVEs have a combined severity score of a maximum 10 out of 10. If successful, an adversary could execute arbitrary code on the targeted device, cause a denial of service or bypass authentication protections.

All users can subscribe to Talos' newest rule detection functionality for as low as $29 a year with a personal account. Be sure and see our business pricing as well here. The Snort 3 release is also here after years of development and improvements, which you can upgrade to here.

Snort's rule blog posts are switching to a weekly recap format, rather than releasing every day a new rule update is released. If you have any feedback on this blog format, please reach out to us on Twitter @Snort
