FAUCET Score

CVE-2015-3953 describes a critical vulnerability in several Hospira infusion systems, including Plum A+, Plum A+3, and Symbiq models, where hard-coded accounts allow unauthorized access. This vulnerability carries a CVSS score of 9.8 (CRITICAL) due to its network-based attack vector, low attack complexity, and potential for complete compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been observed, Hospira recommended closing FTP and TELNET ports on affected devices and has released the Plum 360 system which is not vulnerable.
