CVE-2021-1312

Name of the Vulnerable Software and Affected Versions: Cisco Elastic Services Controller (ESC) (affected versions not specified)

Description: The issue is related to inadequate provisioning of kernel parameters for the maximum number of TCP connections and SYN backlog in the system resource management of Cisco Elastic Services Controller (ESC). This could allow an unauthenticated, remote attacker to cause a denial of service (DoS) to the health monitor API on an affected device by sending a flood of crafted TCP packets. A successful exploit could block TCP listening ports used by the health monitor API. The vulnerability only affects customers who use the health monitor API.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
