F5 Labs Publishes October Update to Sensor Intel Series

F5 Labs just launched the October installment in our growing Sensor Intel Series. The sensors in question come from our data partners Efflux, and allow us to get a sense of what kinds of vulnerabilities attackers are targeting from month to month.

In September, the top-targeted vulnerability was CVE-2018-13379, a credential disclosure vulnerability in various versions of two Fortinet SSL VPNs. While nobody likes to see security tools with vulnerabilities, it is a change from the PHP remote code execution and IoT vulnerabilities that have made up the bulk of the targeting traffic over the last several months.

We’ve also debuted a new visualization type for all 41 tracked vulnerabilities, making it a little easier to identify vulnerabilities with dramatic changes in targeting volume. At various times in the last nine months, CVE-2017-18368, CVE-2022-22947, and the vulnerabilities CVE-2021-22986 and CVE-2022-1388 (which are indistinguishable without examining headers in the HTTP request) have all shown growth rates at or near three orders of magnitude over a period of six to eight weeks, making them the fastest growing vulnerabilities since we’ve started this project.

Stay tuned for the publication of the October SIS in early November. We are always looking for new CVEs to add and new ways to visualize the attack data.
