Cisco IOS Software for Cisco 800 Series Industrial Integrated Services Routers Arbitrary Memory Write Vulnerabilities

Multiple vulnerabilities in the embedded test subsystem of Cisco IOS Software for Cisco 800 Series Industrial Integrated Services Routers could allow an authenticated, local attacker to write arbitrary values to arbitrary locations in the memory space of an affected device.

The vulnerabilities are due to the presence of certain test commands that were intended to be available only in internal development builds of the affected software. An attacker could exploit these vulnerabilities by using these commands on an affected device. A successful exploit could allow the attacker to write arbitrary values to arbitrary locations in the memory space of the affected device.

There are no workarounds that address these vulnerabilities.
