Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Upgrade affected Siemens RUGGEDCOM and SCALANCE devices to firmware version 3.2 or later, where the authorization flaw is corrected. 2. Restrict network access to device management interfaces, ensuring only trusted administrators can reach the web interface, ideally via VPN or secure management networks. 3. Enforce strong authentication mechanisms and consider disabling or limiting guest accounts to prevent unauthorized access. 4. Implement network segmentation to isolate industrial control devices from general IT networks and internet exposure. 5. Monitor device configuration changes and rollback events through centralized logging and alerting systems to detect unauthorized activities promptly. 6. Conduct regular audits of user roles and permissions on these devices to ensure least privilege principles are maintained. 7. Employ intrusion detection systems tailored for OT environments to identify anomalous behavior related to configuration management. 8. Develop and test incident response plans specific to configuration integrity breaches in industrial devices.

The "Load Rollback" functionality in the web interface of affected products contains an incorrect authorization check vulnerability. This could allow an authenticated remote attacker with "guest" role to make the affected product roll back configuration changes made by privileged users.

Impact

For European organizations, especially those operating critical infrastructure and industrial control systems, this vulnerability poses a significant risk to operational integrity. Unauthorized rollback of device configurations can lead to the reintroduction of insecure settings, disablement of security controls, or disruption of network segmentation policies. This undermines trust in device configurations and may facilitate further attacks by adversaries exploiting weakened defenses. Given Siemens' strong market presence in Europe’s industrial sectors—including Germany, France, Italy, Spain, and the UK—many organizations could be affected. The vulnerability could impact sectors such as energy production and distribution, manufacturing plants, transportation networks, and utilities, where these devices are integral to network reliability and security. The potential for an attacker with minimal privileges to alter device configurations without detection increases the risk of prolonged undetected compromise and operational disruptions. Although availability is not directly impacted, the integrity breach could cascade into broader operational issues or safety hazards in industrial environments.

Summary

CVE-2025-40567 is an authorization bypass vulnerability classified under CWE-863, discovered in Siemens RUGGEDCOM RST2428P and multiple SCALANCE series devices (including XCH328, XCM324, XCM328, XCM332, XRH334, and various XRM334 models) with firmware versions earlier than 3.2. The vulnerability specifically affects the "Load Rollback" functionality accessible via the device's web interface. Normally, only privileged users should be able to perform configuration rollbacks to restore previous device settings. However, due to an incorrect authorization check, an authenticated user assigned the "guest" role can invoke this rollback feature. This unauthorized rollback can negate configuration changes made by administrators or other privileged users, potentially reverting security settings or operational parameters to less secure or outdated states. The attack vector requires network access and valid guest credentials but does not require user interaction beyond authentication. The CVSS v3.1 base score is 6.5 (medium severity), reflecting the vulnerability's impact on integrity without affecting confidentiality or availability. No public exploits have been reported yet, but the vulnerability could be leveraged in targeted attacks against industrial control systems (ICS) or critical infrastructure networks that utilize these Siemens devices. The affected devices are commonly deployed in industrial environments such as energy, manufacturing, transportation, and utilities, making this vulnerability relevant to operational technology (OT) security.

The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
