Threat metrics

Exploit Maturity: POC

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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

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 or the CVSS exploit maturity 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 CVE-2025-9138 effectively, European organizations should: 1) Enforce strict access control and multi-factor authentication (MFA) for all admin accounts to reduce the risk of credential compromise. 2) Regularly audit admin activities and monitor for unusual behavior indicative of insider threats or compromised accounts. 3) Apply input validation and output encoding on the 'Title' argument and other user-controllable inputs in the Scada-LTS application, even if the vendor has not yet released a patch. 4) Isolate Scada-LTS management interfaces from general network access, restricting them to trusted administrative networks or VPNs. 5) Implement Content Security Policy (CSP) headers to limit the impact of potential XSS by restricting the execution of unauthorized scripts. 6) Stay updated with vendor advisories and apply patches promptly once available. 7) Conduct regular security training for administrators emphasizing the risks of misuse of admin privileges and the importance of secure credential handling.

Description

A vulnerability was found in Scada-LTS 2.7.8.1. Affected is an unknown function of the file pointHierarchy/new/. Performing manipulation of the argument Title results in cross site scripting. The attack is possible to be carried out remotely. The exploit has been made public and could be used. The vendor explains: "[T]he risks of indicated vulnerabilities seem to be minimal as all scenarios likely require admin permissions. Moreover, regardless our team fixes those vulnerabilities - the overall risk change to the user due to malicious admin actions will not be lower. An admin user - by definition - has full control over HTML and JS code that is delivered to users in regular synoptic panels. In other words - due to the design of the system it is not possible to limit the admin user to attack the users."

Impact

For European organizations using Scada-LTS 2.7.8.1, particularly those in critical infrastructure sectors such as energy, water management, and industrial automation, this vulnerability poses a moderate risk. While exploitation requires admin privileges, a compromised or malicious admin account could leverage this XSS flaw to execute arbitrary scripts, potentially manipulating the system's monitoring dashboards or misleading operators. This could result in incorrect operational decisions or facilitate further attacks such as privilege escalation or lateral movement within the network. However, since the vulnerability does not allow remote unauthenticated attackers to exploit it, the primary risk is insider threat or compromised admin credentials. The impact on confidentiality and availability is limited, but integrity and operational trust could be affected. European organizations with stringent access controls and monitoring may mitigate the risk, but those with weaker admin account protections or less mature security practices could be more vulnerable.

Summary

CVE-2025-9138 is a cross-site scripting (XSS) vulnerability identified in Scada-LTS version 2.7.8.1, specifically within an unspecified function related to the file path pointHierarchy/new/. The vulnerability arises from improper sanitization or validation of the 'Title' argument, allowing an attacker to inject malicious JavaScript code. This vulnerability can be exploited remotely without requiring user interaction, but it does require the attacker to have at least limited privileges (admin permissions) on the system. The vendor notes that the risk is minimal because only users with admin-level access can exploit this flaw, and such users inherently have the capability to inject arbitrary HTML and JavaScript into synoptic panels, which are used to visualize system data. Therefore, the vulnerability does not significantly increase the risk beyond what a malicious admin could already do. The CVSS 4.0 base score is 5.1 (medium severity), reflecting the moderate impact and the requirement for privileges. No public exploit is currently known to be in widespread use, but proof-of-concept code has been made public. The vulnerability does not affect confidentiality or availability directly but can impact the integrity and trustworthiness of the user interface by enabling script injection, potentially leading to session hijacking or unauthorized actions within the context of the admin user interface.
