CVE-2019-13946
7.5 · HIGHOverview
CVE-2019-13946 is a high-severity vulnerability affecting siemens dk_standard_ethernet_controller. It was published on February 11, 2020 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
Profinet-IO (PNIO) stack versions prior V06.00 do not properly limit
internal resource allocation when multiple legitimate diagnostic package
requests are sent to the DCE-RPC interface.
This could lead to a denial of service condition due to lack of memory
for devices that include a vulnerable version of the stack.
The security vulnerability could be exploited by an attacker with network
access to an affected device. Successful exploitation requires no system
privileges and no user interaction. An attacker could use the vulnerability
to compromise the availability of the device.
Remediation
Check the references section for vendor advisories and patches from siemens. Update dk_standard_ethernet_controller to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
