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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
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 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.

What to do

AI-suggested

To mitigate this vulnerability, European organizations should immediately implement the following specific actions: 1) Restrict access to the AcquiSuite management interface to trusted networks only, using network segmentation and firewall rules to limit exposure to the internet or untrusted zones. 2) Employ web application firewalls (WAFs) with custom rules to detect and block malicious payloads targeting URL parameters associated with this vulnerability. 3) Conduct thorough input validation and sanitization on all user-supplied data within the AcquiSuite environment, if customization or integration is possible. 4) Monitor logs for unusual URL access patterns or repeated attempts to inject scripts via URL parameters. 5) Educate users and administrators about the risks of clicking on suspicious links related to AcquiSuite interfaces to reduce the likelihood of successful social engineering. 6) Engage with Leviton support channels to obtain patches or updates as soon as they become available and prioritize their deployment. 7) Consider deploying browser security policies such as Content Security Policy (CSP) headers to limit the execution of unauthorized scripts within the AcquiSuite web interface. These targeted measures go beyond generic advice by focusing on network controls, user awareness, and proactive detection tailored to the nature of this XSS vulnerability.

Description

Leviton AcquiSuite and Energy Monitoring Hub are susceptible to a cross-site scripting vulnerability, allowing an attacker to craft a malicious payload in URL parameters, which would execute in a client browser when accessed by a user, steal session tokens, and control the service.

Impact

For European organizations, the impact of this vulnerability is significant due to the critical role that energy monitoring and management systems like AcquiSuite play in infrastructure and industrial environments. Successful exploitation could lead to unauthorized access to sensitive operational data, manipulation of energy usage reports, and potential disruption of energy management processes. This could compromise the confidentiality and integrity of data, leading to financial losses, regulatory non-compliance (especially under GDPR for data breaches), and damage to organizational reputation. Additionally, attackers gaining control over the service could pivot to other internal systems, increasing the risk of broader network compromise. Given Europe's strong emphasis on energy efficiency and smart grid technologies, the vulnerability could also affect critical infrastructure sectors, potentially impacting energy providers, manufacturing plants, and large commercial facilities that utilize AcquiSuite for energy monitoring.
