Summary

SSA-099819: Denial of Service Vulnerability in SENTRON 3NA COM Fuse

Notes

Summary: SENTRON 3NA COM Fuse contains a Denial-of-Service vulnerability. Improper handling of a network management message could allow an attacker to trigger a denial-of-service (DoS) condition. Successful exploitation may require the affected network to be re-established to restore normal operation.

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. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity

CVE-2024-7322

A ZigBee coordinator, router, or end device may change their node ID when an unsolicited encrypted rejoin response is received, this change in node ID causes Denial of Service (DoS). To recover from this DoS, the network must be re-established
