CVE-2020-3188 is a denial-of-service (DoS) vulnerability in Cisco Firepower Threat Defense (FTD) Software, affecting its management connections. The flaw stems from an excessively long default session timeout for remote management, allowing unauthenticated attackers to flood the device with crafted connections. This can lead to the remote management interface or Cisco Firepower Device Manager (FDM) becoming unresponsive, though user traffic remains unaffected. Rated 5.3 MEDIUM on CVSS, the attack requires no privileges or user interaction, but its impact is limited to management functions. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
