Vulnerability from variot

Hospira Plum A+ Infusion System version 13.4 and prior, Plum A+3 Infusion System version 13.6 and prior, and Symbiq Infusion System, version 3.13 and prior give unauthenticated users root privileges on Port 23/TELNET by default. An unauthorized user could issue commands to the pump. Hospira recommends that customers close Port 23/TELNET on the affected devices. Hospira has also released the Plum 360 Infusion System which is not vulnerable to this issue. Multiple Hospira products are prone to an authorization security-bypass vulnerability. An attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions; this may aid in launching further attacks. An issue in the Hospira Plum A+ and Symbiq Infusion Systems could allow an unauthenticated, remote malicious user to execute arbitrary commands of an affected system.

The issue exists because the affected software uses an improper mechanism to perform authorization checks on port 23/Telnet by default. An unauthenticated, remote attacker could exploit this issue by transmitting arbitrary commands on the affected system using a vulnerable port. A successful exploit could allow the malicious user to execute arbitrary commands and modify the configuration of the pump on an affected system with root-level privileges.

ICS-CERT has confirmed the vulnerability; however, updated software is not available
