Summary
SSA-876049: Prototype Pollution Vulnerability in Axios Library Affecting Siemens gWAP Before V3.1.1
Notes
Summary: Siemens gPROMS Web Applications Publisher (gWAP) is affected by a remote code execution vulnerability introduced through a third-party component, namely the Axios HTTP client library. The vulnerability stems from a specific "Gadget" attack chain that allows prototype pollution in other third-party libraries, potentially allowing an attacker to execute arbitrary code. Siemens has released a new version for gWAP and recommends to update to the latest version.
General Recommendations: As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals.
