HHS and American Hospital Association Alert Providers to Act Now on “Citrix Bleed” Vulnerability

The United States Health & Human Services Department (HHS) Health Sector Cybersecurity Coordination Center (HH3) issued an HH3 Sector Alert for a software vulnerability dubbed the “Citrix Bleed“. The HH3 Alert advises on a Citrix security advisory regarding a zero-day vulnerability that impacts the NetScaler ADC (formerly Citrix ADC) and NetScaler Gateway (fomerly Citrix Gateway). The HH3 Alert, issued on November 30, 2023, urges healthcare organizations to upgrade their devices to prevent damage to the health sector from cyber attacks, including ransomware.

Per the HH3 Alert, even if the patch that Citrix released for this vulnerability was implemented, Citrix warns that compromised sessions will still be active after the patch is implemented. Organizations should follow the Citrix guidance to upgrade devices and remove any active or persistent sessions with the commands listed in the Alert.

On December 1, 2023, the American Hospital Association (AHA) similarly alerted its members about the Citrix Bleed issuing its own alert titled, “Urgent: Hospital Action Needed to Protect Against ‘Citrix Bleed’ Threat.” AHA also published the following article the same day: “HHS-HC3 calls for immediate hospital action to protect against ‘Citrix Bleed’ vulnerability and ransomware threat.”

In its weekly Medicare MLN Connects news on December 7, 2023, the Centers for Medicare and Medicaid Services (CMS) asks providers to make sure their IT department reads the information and takes necessary action. Providers also should share the HH3 Alert with their network clearinghouse and vendors.

Relatedly, on December 6, 2023, CNN reported that HHS shared exclusively with CNN a plan focused on getting more money and training to small and rural health care providers who lack dedicated cybersecurity staff. CNN reported that Biden administration officials “have long been concerned that software providers continue to sell insecure products that hackers are too easily able to exploit.” Click here to read the full CNN article, titled “US health officials call for surge in funding and support for hospitals in wake of cyberattacks that diverted ambulances,” by Sean Lyngass.
