Exploited Vulnerabilities

CISA KEV update puts Cisco SD-WAN, PaperCut and TeamCity into the exposure queue

CISA added multiple exploited vulnerabilities on April 20, including Cisco Catalyst SD-WAN Manager issues, PaperCut NG/MF CVE-2023-27351 and JetBrains TeamCity CVE-2024-27199. Treat the update as a concrete exposure-validation list rather than a general patching reminder.

The highest enterprise risk is unmanaged infrastructure: SD-WAN managers, print platforms and build systems often sit close to privileged network paths, developer workflows or internal administration.
