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

Exploitation evidence

Disclosed: evidence found.
CVE published 20 Aug 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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

Organizations should immediately verify if their Scada-LTS installations are running affected versions (2.7.8.0 or 2.7.8.1) and plan for an upgrade to a patched version once available. In the absence of an official patch, implement web application firewall (WAF) rules to detect and block suspicious input patterns targeting the 'Alias' parameter in maintenance_events.shtm. Employ strict input validation and output encoding on all user-supplied data within the SCADA web interface to prevent script injection. Restrict access to the SCADA web interface to trusted networks and enforce multi-factor authentication to reduce the risk of unauthorized access. Conduct user awareness training for operators to recognize phishing attempts that may leverage this XSS vulnerability. Regularly monitor logs for unusual activity related to the maintenance_events.shtm page. Additionally, consider deploying Content Security Policy (CSP) headers to limit the execution of unauthorized scripts within the SCADA web interface environment.

Description

A vulnerability was detected in Scada-LTS up to 2.7.8.1. The affected element is an unknown function of the file maintenance_events.shtm. The manipulation of the argument Alias results in cross site scripting. The attack can be executed remotely. The exploit is now public and may be used.

Impact

For European organizations, especially those operating critical infrastructure such as energy grids, water treatment plants, manufacturing facilities, and transportation systems that utilize Scada-LTS, this vulnerability poses a significant risk. Successful exploitation could allow attackers to hijack user sessions or inject malicious scripts that manipulate control interfaces, potentially leading to operational disruptions or unauthorized data access. Given the reliance on SCADA systems for real-time monitoring and control, even limited integrity or confidentiality breaches can cascade into safety hazards or service outages. The medium severity rating suggests that while the vulnerability alone may not cause full system compromise, it can serve as a foothold for more sophisticated attacks or social engineering campaigns targeting system operators. The remote exploitability and public exploit availability increase the urgency for European entities to address this issue promptly to prevent exploitation attempts, especially in sectors under heightened threat from cyber espionage or sabotage.
