Siemens SCALANCE XRM334 up to 3.1 Web Interface race condition

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as problematic, was found in Siemens RUGGEDCOM RST2428P, SCALANCE XC316-8, SCALANCE XC324-4, SCALANCE XC324-4 EEC, SCALANCE XC332, SCALANCE XC416-8, SCALANCE XC424-4, SCALANCE XC432, SCALANCE XCH328, SCALANCE XCM324, SCALANCE XCM328, SCALANCE XCM332, SCALANCE XR302-32, SCALANCE XR322-12, SCALANCE XR326-8, SCALANCE XR326-8 EEC, SCALANCE XR502-32, SCALANCE XR522-12, SCALANCE XR526-8, SCALANCE XRH334 and SCALANCE XRM334 up to 3.1. This affects an unknown code of the component Web Interface. The manipulation with an unknown input leads to a race condition vulnerability. CWE is classifying the issue as CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. This is going to have an impact on integrity. The summary by CVE is:

A vulnerability has been identified in RUGGEDCOM RST2428P (6GK6242-6PA00) (All versions < V3.2), SCALANCE XCH328 (6GK5328-4TS01-2EC2) (All versions < V3.2), SCALANCE XCM324 (6GK5324-8TS01-2AC2) (All versions < V3.2), SCALANCE XCM328 (6GK5328-4TS01-2AC2) (All versions < V3.2), SCALANCE XCM332 (6GK5332-0GA01-2AC2) (All versions < V3.2), SCALANCE XRH334 (24 V DC, 8xFO, CC) (6GK5334-2TS01-2ER3) (All versions < V3.2), SCALANCE XRM334 (230 V AC, 12xFO) (6GK5334-3TS01-3AR3) (All versions < V3.2), SCALANCE XRM334 (230 V AC, 8xFO) (6GK5334-2TS01-3AR3) (All versions < V3.2), SCALANCE XRM334 (230V AC, 2x10G, 24xSFP, 8xSFP+) (6GK5334-5TS01-3AR3) (All versions < V3.2), SCALANCE XRM334 (24 V DC, 12xFO) (6GK5334-3TS01-2AR3) (All versions < V3.2), SCALANCE XRM334 (24 V DC, 8xFO) (6GK5334-2TS01-2AR3) (All versions < V3.2), SCALANCE XRM334 (24V DC, 2x10G, 24xSFP, 8xSFP+) (6GK5334-5TS01-2AR3) (All versions < V3.2), SCALANCE XRM334 (2x230 V AC, 12xFO) (6GK5334-3TS01-4AR3) (All versions < V3.2), SCALANCE XRM334 (2x230 V AC, 8xFO) (6GK5334-2TS01-4AR3) (All versions < V3.2), SCALANCE XRM334 (2x230V AC, 2x10G, 24xSFP, 8xSFP+) (6GK5334-5TS01-4AR3) (All versions < V3.2). The "Load Configuration from Local PC" functionality in the web interface of affected products contains a race condition vulnerability. This could allow an authenticated remote attacker to make the affected product load an attacker controlled configuration instead of the legitimate one. Successful exploitation requires that a legitimate administrator invokes the functionality and the attacker wins the race condition.

The advisory is shared at cert-portal.siemens.com. This vulnerability is uniquely identified as CVE-2025-40569 since 04/16/2025. The exploitability is told to be difficult. It is possible to initiate the attack remotely. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available.

Upgrading to version 3.2 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2025-17679). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
