SIMATIC RTLS Locating Manager: Insufficiently Protected Credentials
CVE-2025-40751 is a high-severity insufficiently protected credentials vulnerability in SIMATIC RTLS Locating Manager from Siemens, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version V3.3 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 0.13% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
A vulnerability has been identified in SIMATIC RTLS Locating Manager (All versions < V3.3). Affected SIMATIC RTLS Locating Manager Report Clients do not properly protect credentials that are used to authenticate to the server. This could allow an authenticated local attacker to extract the credentials and use them to escalate their access rights from the Manager to the Systemadministrator role.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
