SIMATIC RTLS Locating Manager: Use of Hard-coded Cryptographic Key

Published Updated By the CyberSecBulletin desk

CVE-2024-30207 is a critical-severity use of hard-coded cryptographic key vulnerability in SIMATIC RTLS Locating Manager from Siemens, with a CVSS 3.1 base score of 10.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version V3.0.1.1 as the first without the flaw, so updating SIMATIC RTLS Locating Manager to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.84% chance of exploitation within 30 days, higher than 58% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update SIMATIC RTLS Locating Manager to V3.0.1.1 or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

A vulnerability has been identified in SIMATIC RTLS Locating Manager (6GT2780-0DA00) (All versions < V3.0.1.1), SIMATIC RTLS Locating Manager (6GT2780-0DA10) (All versions < V3.0.1.1), SIMATIC RTLS Locating Manager (6GT2780-0DA20) (All versions < V3.0.1.1), SIMATIC RTLS Locating Manager (6GT2780-0DA30) (All versions < V3.0.1.1), SIMATIC RTLS Locating Manager (6GT2780-1EA10) (All versions < V3.0.1.1), SIMATIC RTLS Locating Manager (6GT2780-1EA20) (All versions < V3.0.1.1), SIMATIC RTLS Locating Manager (6GT2780-1EA30) (All versions < V3.0.1.1). The affected systems use symmetric cryptography with a hard-coded key to protect the communication between client and server. This could allow an unauthenticated remote attacker to compromise confidentiality and integrity of the communication and, subsequently, availability of the system. A successful exploit requires the attacker to gain knowledge of the hard-coded key and to be able to intercept the communication between client and server on the network.
