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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
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 on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 30 May 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 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

Immediate mitigation should include restricting access to the wivia 5 web interface to trusted networks and users only, minimizing exposure to potential attackers.
Enforce the principle of least privilege by limiting moderator user accounts and their usage.
Educate and alert moderator users about the risk of interacting with untrusted or suspicious inputs when managing the device.
Monitor web interface logs and network traffic for unusual activities that could indicate exploitation attempts.
Apply any vendor-provided patches or updates as soon as they become available.
If patches are not yet available, consider deploying web application firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting the wivia 5 interface.
Conduct regular security assessments and penetration tests focusing on the web management interfaces to identify and remediate similar vulnerabilities proactively.
Implement multi-factor authentication (MFA) for moderator accounts to reduce the impact of credential theft via XSS.

Description

Cross-site scripting vulnerability exists in wivia 5 all versions. If exploited, when a user connects to the affected device with a specific operation, an arbitrary script may be executed on the web browser of the moderator user.

Impact

For European organizations using wivia 5 devices, this vulnerability poses a risk primarily to the confidentiality and integrity of their web management interfaces. Since the vulnerability requires a moderator user to interact with the malicious payload, the threat is significant in environments where privileged users access the device's web interface regularly. Exploitation could lead to session hijacking, unauthorized command execution, or theft of sensitive information such as credentials or configuration data. This could facilitate further lateral movement or persistent access within the network. Given that wivia 5 is a specialized product, the impact depends on its deployment scale in European enterprises or government agencies. If used in critical infrastructure or sensitive environments, the risk is elevated. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often weaponize such vulnerabilities rapidly after disclosure. The medium CVSS score reflects the moderate ease of exploitation combined with the requirement for user interaction and privileges. European organizations must consider this vulnerability in their risk assessments, particularly those with privileged users managing wivia 5 devices.
