CVE-2017-12318

High
Published: Translated: NVD NIST

Summary

A vulnerability in the TCP state machine of Cisco RF Gateway 1 devices could allow an unauthenticated, remote attacker to prevent an affected device from delivering switched digital video (SDV) or video on demand (VoD) streams, resulting in a denial of service (DoS) condition. The vulnerability is due to a processing error with TCP connections to the affected device.

Risk Assessment

An attacker could exploit this vulnerability by establishing a large number of TCP connections and not actively closing them, potentially disrupting video services for users. This could impact the availability of video services within the organization.

Recommendation

It is recommended to monitor and limit the number of TCP connections to Cisco RF Gateway 1 devices and implement detection and protection mechanisms against DoS attacks.
