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), 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

1. Immediate patching: Organizations should monitor for official patches or updates from the Scada-LTS project addressing this vulnerability and apply them promptly once available. 2. Input validation and sanitization: Until a patch is released, implement web application firewalls (WAFs) or reverse proxies with custom rules to detect and block suspicious input patterns targeting the name, userList, and address parameters. 3. User awareness and training: Educate users with access to the SCADA interface about the risks of clicking unknown links or interacting with untrusted content to reduce the likelihood of successful XSS exploitation. 4. Segmentation and access control: Restrict access to the SCADA-LTS management interface to trusted networks and users only, employing VPNs and multi-factor authentication to reduce exposure. 5. Monitoring and logging: Enhance logging of web interface activities and monitor for anomalous behavior indicative of XSS exploitation attempts, such as unusual parameter values or repeated failed access attempts. 6. Content Security Policy (CSP): Where possible, implement CSP headers to limit the execution of unauthorized scripts within the SCADA web interface. 7. Incident response readiness: Prepare to respond to potential exploitation by having procedures in place to isolate affected systems and conduct forensic analysis.

Description

A security flaw has been discovered in Scada-LTS 2.7.8.1. This affects an unknown part of the file mailing_lists.shtm. The manipulation of the argument name/userList/address results in cross site scripting. It is possible to launch the attack remotely. The exploit has been released to the public and may be exploited.

Impact

For European organizations, particularly those operating critical infrastructure such as energy, water treatment, manufacturing, and transportation sectors that rely on SCADA systems, this vulnerability poses a tangible risk. Exploitation could lead to unauthorized access to control interfaces, data leakage, and manipulation of operational parameters through session hijacking or social engineering attacks. Although the vulnerability does not directly allow system takeover or denial of service, the ability to execute scripts in the context of legitimate users could facilitate lateral movement or escalation of privileges within the network. Given the increasing digitization and interconnectivity of industrial systems in Europe, this vulnerability could undermine operational integrity and safety, potentially causing economic and reputational damage. The medium severity rating suggests that while immediate catastrophic impacts are unlikely, the vulnerability should not be ignored, especially in environments where SCADA-LTS is deployed without additional compensating controls.

Summary

CVE-2025-9143 is a cross-site scripting (XSS) vulnerability identified in Scada-LTS version 2.7.8.1, specifically affecting an unspecified portion of the file mailing_lists.shtm. The vulnerability arises from improper sanitization of user-controllable input parameters, namely name, userList, and address. An attacker can manipulate these parameters to inject malicious scripts that execute in the context of the victim's browser. This flaw can be exploited remotely without authentication, although user interaction is required to trigger the malicious payload, such as by visiting a crafted URL or interacting with a compromised interface. The vulnerability has a CVSS 4.0 base score of 5.1, indicating a medium severity level. The attack vector is network-based with low attack complexity and no privileges required, but user interaction is necessary. The impact primarily affects confidentiality and integrity at a low level, with no direct impact on availability or system control. While no public exploit is currently known to be actively used in the wild, the exploit code has been publicly released, increasing the risk of opportunistic attacks. Scada-LTS is an open-source SCADA (Supervisory Control and Data Acquisition) platform used for industrial control systems (ICS) monitoring and management, making this vulnerability relevant to critical infrastructure environments. The vulnerability could allow attackers to steal session cookies, perform actions on behalf of authenticated users, or conduct phishing attacks within the SCADA management interface, potentially leading to further compromise of industrial control operations.
