Attack Vector: Network
Attack Complexity: Low
Privileges Required: High
User Interaction: None
Scope: Changed
Confidentiality: High
Integrity: None
Availability: None

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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: 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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 3 Jul 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

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 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 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 effectively, European organizations should: 1) Immediately review and restrict dashboard creation permissions to only trusted, highly privileged users to reduce the risk of malicious input injection. 2) Implement strict input validation and output encoding on the dashboard name fields at the application level, ensuring that any user-supplied data is properly sanitized before rendering. 3) Monitor and audit dashboard creation activities and web interface logs for unusual or suspicious entries that may indicate attempted exploitation. 4) Network segmentation should be enforced to isolate MEAC300-FNADE4 devices from general IT networks, limiting exposure to potentially compromised systems. 5) Apply compensating controls such as Web Application Firewalls (WAFs) configured to detect and block XSS payloads targeting the device's web interface. 6) Engage with Endress+Hauser for timely patches or firmware updates addressing this vulnerability and plan for prompt deployment once available. 7) Conduct user training and awareness programs for operators and administrators managing these devices to recognize and report suspicious activities. 8) Consider implementing multi-factor authentication and enhanced access controls to reduce the risk of privilege escalation that could enable exploitation.

Description

The web application is susceptible to cross-site-scripting attacks. An attacker who can create new dashboards can inject JavaScript code into the dashboard name which will be executed when the website is loaded.

Impact

For European organizations, especially those in critical infrastructure sectors such as manufacturing, energy, water treatment, and chemical processing, this vulnerability poses a notable risk. The MEAC300-FNADE4 is used for process monitoring and control, meaning that unauthorized access or data leakage could disrupt operational confidentiality and potentially expose sensitive industrial process data. Although the vulnerability does not directly impact system integrity or availability, the confidentiality breach could facilitate further attacks or espionage activities. European companies relying on Endress+Hauser devices may face risks of intellectual property theft, exposure of operational parameters, or unauthorized surveillance. The requirement for high privileges to exploit the vulnerability somewhat limits the attack surface to insiders or attackers who have already gained elevated access, but the absence of user interaction means automated exploitation within compromised networks is feasible. This could be particularly impactful in highly regulated sectors where data confidentiality is paramount and compliance with GDPR and other data protection regulations is mandatory. Additionally, the scope change in the vulnerability suggests that exploitation could affect multiple components or systems interconnected with the vulnerable device, amplifying the potential impact.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
