Confidentiality: Low
Integrity: Low
Availability: Low

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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.

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 2026-10-26.

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

To mitigate this vulnerability, European organizations should: 1) Immediately identify and inventory all SIMATIC RTLS Locating Manager deployments and verify their version, prioritizing upgrades to version 3.3 or later once available. 2) Implement strict access controls and monitoring on systems hosting the Report Clients to prevent unauthorized local access. 3) Enforce the principle of least privilege for all user accounts, especially limiting access to the Report Client to only trusted personnel. 4) Employ endpoint security solutions to detect and prevent credential extraction techniques on local machines. 5) Use network segmentation to isolate RTLS infrastructure from broader corporate networks, reducing the risk of lateral movement. 6) Monitor logs for unusual privilege escalation attempts or access patterns related to the RTLS Manager. 7) Engage with Siemens support for any interim patches or workarounds and apply them promptly. 8) Conduct regular security awareness training emphasizing the risks of credential theft and insider threats. These steps go beyond generic advice by focusing on operational technology security hygiene and insider threat mitigation specific to the affected product environment.

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.

Impact

For European organizations using Siemens SIMATIC RTLS Locating Manager, this vulnerability poses a significant risk to operational technology (OT) environments, particularly in industrial automation and manufacturing sectors where Siemens products are widely deployed. The ability for a local authenticated attacker to escalate privileges to Systemadministrator could lead to unauthorized control over RTLS (Real-Time Locating System) infrastructure, potentially disrupting asset tracking, production workflows, and safety monitoring. Confidentiality of sensitive operational data could be compromised, and integrity of location data manipulated, leading to erroneous operational decisions. Availability could also be impacted if administrative privileges are used to disrupt or disable the system. Given Siemens' strong market presence in Europe, especially in Germany, France, Italy, and the UK, the threat could affect critical infrastructure and manufacturing plants, increasing the risk of industrial espionage, sabotage, or safety incidents. The requirement for local authentication limits remote exploitation but insider threats or compromised internal accounts could leverage this vulnerability effectively.
