PwnedPiper PTS Security Flaws Threaten 80% of Hospitals in the U.S.

Cybersecurity researchers on Monday disclosed a set of nine vulnerabilities acknowledged as “PwnedPiper” that remaining a widely-applied pneumatic tube program (PTS) vulnerable to crucial assaults, which include a probability of full takeover.

The protection weaknesses, disclosed by American cybersecurity agency Armis, effect the Translogic PTS technique by Swisslog Health care, which is installed in about 80% of all major hospitals in North The us and in no much less than 3,000 hospitals worldwide.

“These vulnerabilities can permit an unauthenticated attacker to take above Translogic PTS stations and primarily gain entire control in excess of the PTS community of a target clinic,” Armis scientists Ben Seri and Barak Hadad stated. “This style of manage could empower advanced and worrisome ransomware attacks, as effectively as allow attackers to leak delicate healthcare facility data.”

Pneumatic tube systems are inner logistics and transport options that are employed to transport blood samples in clinic options to diagnostic laboratories securely.

Prosperous exploitation of the problems, hence, could result in leakage of sensitive facts, allow an adversary to manipulate data, and even compromise the PTS community to carry out a guy-in-the-middle (MitM) assault and deploy ransomware, therefore properly halting the operations of the medical center.

The information about the 9 PwndPiper vulnerabilities are shown as follows –

  • CVE-2021-37161 – Underflow in udpRXThread
  • CVE-2021-37162 – Overflow in sccProcessMsg
  • CVE-2021-37163 – Two hardcoded passwords accessible by the Telnet server
  • CVE-2021-37164 – Off-by-three stack overflow in tcpTxThread
  • CVE-2021-37165 – Overflow in hmiProcessMsg
  • CVE-2021-37166 – GUI socket Denial Of Support
  • CVE-2021-37167 – User script operate by root can be applied for PE
  • CVE-2021-37160 – Unauthenticated, unencrypted, unsigned firmware up grade

In a nutshell, the flaws — which issue privilege escalation, memory corruption, and denial-of-service — could be abused to acquire root entry, attain remote-code-execution or denial-of-assistance, and even worse, allow an attacker to maintain persistence on compromised PTS stations by using an insecure firmware improve method, top to unauthenticated distant-code-execution. It is also value noting that a patch for CVE-2021-37160 is expected to be delivered at a long term day.

Prevent Data Breaches

“The prospective for pneumatic tube stations (where by the firmware is deployed) to be compromised is dependent on a bad actor who has access to the facility’s information technological innovation network and who could lead to extra destruction by leveraging these exploits,” Swisslog Health care stated in an independent advisory published nowadays.

Translogic PTS system customers are very proposed to update to the latest firmware (Nexus Manage Panel version 7.2.5.7) to mitigate any likely threat that may perhaps occur out of serious-globe exploitation of the shortcomings.

“This study sheds light on systems that are concealed in plain sight but are nonetheless a important building block to modern-day-working day health care,” Seri and Hadad said. “Knowledge that affected person care relies upon not only on health-related products, but also on the operational infrastructure of a healthcare facility is an crucial milestone to securing healthcare environments.”
