Detailsinfo

A vulnerability classified as very critical has been found in B. Braun Battery Pack SP L90/L92. Affected is an unknown part of the component Web Server. The manipulation with an unknown input leads to a eval injection vulnerability. CWE is classifying the issue as CWE-95. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval"). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

An improper neutralization of directives in dynamically evaluated code vulnerability in the WiFi Battery embedded web server in versions L90/U70 and L92/U92 can be used to gain administrative access to the WiFi communication module. An authenticated user, having access to both the medical device WiFi network (such as a biomedical engineering staff member) and the specific B.Braun Battery Pack SP with WiFi web server credentials, could get administrative (root) access on the infusion pump communication module. This could be used as a vector to start further attacks
