Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, Cisco IOS Software for Cisco 809 and 829 Industrial Integrated Services Routers (Industrial ISRs) and Cisco 1000 Series Connected Grid Routers (CGR1000) is affected by multiple arbitrary code execution vulnerabilities, as follows:

- A vulnerability in the area of code that manages inter-VM signaling due to incorrect bounds checking. An unauthenticated, remote attacker can exploit this, by sending malicious packets to an affected device, in order to execute arbitrary code on an affected system or cause the system to crash and reload.
(CVE-2020-3198)

- A vulnerability in one of the diagnostic test CLI commands. This exists because, under specific circumstances, the affected software permits the modification of the device's run-time memory. An authenticated, local attacker can exploit this, by authenticating to the targeted device and issuing a specific diagnostic test command at the CLI in order to execute arbitrary code on an affected device.
(CVE-2020-3258)
