Rockwell Automation Stratix Cisco IOS and IOS XE Software H.323 Message Validation Denial of Service (CVE-2016-6384)

high Tenable OT Security Plugin ID 501812

Synopsis

The remote OT asset is affected by a vulnerability.

Description

A vulnerability in the H.323 subsystem of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to create a denial of service (DoS) condition on an affected device. The vulnerability is due to a failure to properly validate certain fields in an H.323 protocol suite message. When processing the malicious message, the affected device may attempt to access an invalid memory region, resulting in a crash. An attacker who can submit an H.323 packet designed to trigger the vulnerability could cause the affected device to crash and restart.
