DHS issues new emergency guidance on SolarWinds Orion Code compromise

The Department of Homeland Security (DHS) has issued new emergency guidance on the SolarWinds Orion Code compromise and supply chain vulnerability.

Late Tuesday night, DHS published new supplemental guidance with recommendations to mitigate the SolarWinds Orion Code compromise. This is the second supplement to the Emergency Directive 21-01 first published on December 13, 2020. Supplemental Guidance v1 was also added on December 18, 2020.

DHS urges all federal agencies to upgrade their SolarWinds Orion systems by year-end or they will need to take those systems offline (emphasis in bold added):

“Specifically, all federal agencies operating versions of the SolarWinds Orion platform other than those identified as ‘affected versions’ below are required to use at least SolarWinds Orion Platform version 2020.2.1HF2. The National Security Agency (NSA) has examined this version and verified that it eliminates the previously identified malicious code. Given the number and nature of disclosed and undisclosed vulnerabilities in SolarWinds Orion, all instances that remain connected to federal networks must be updated to 2020.2.1 HF2 by COB December 31, 2020.”


In addition, affected versions that should be powered down or removed from networks based on ED 21-01 include: 2019.4 HF5, 2020.2 RC1, 2020.2 RC2, 2020.2, 2020.2 HF1. All others should be upgraded to 2020.2.1 HF2
