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 16 Oct 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

To mitigate CVE-2025-55072, organizations should first verify if patches or updates are available from NEOJAPAN Inc. and apply them promptly. In the absence of official patches, implement strict input validation on all user-supplied data to prevent injection of malicious scripts. Employ robust output encoding/escaping techniques on all data rendered in the web interface to neutralize any embedded scripts. Restrict user privileges to the minimum necessary to reduce the risk of malicious input from less trusted users. Enable Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers. Conduct regular security awareness training to educate users about the risks of interacting with suspicious content. Monitor application logs for unusual activities that may indicate attempted exploitation. Consider deploying web application firewalls (WAF) with rules tailored to detect and block XSS payloads targeting desknet's NEO. Finally, isolate the desknet's NEO environment within segmented network zones to limit potential lateral movement in case of compromise.

Description

Stored cross-site scripting (XSS) vulnerability in desknet's NEO V2.0R1.0 to V9.0R2.0 allow execution of arbitrary JavaScript in a user’s web browser.

Impact

For European organizations, the impact of CVE-2025-55072 can be substantial, especially in sectors relying on desknet's NEO for internal communication and collaboration, such as government agencies, educational institutions, and enterprises. Exploitation could lead to unauthorized access to sensitive information, including internal documents, emails, and user credentials. This can result in data breaches, loss of intellectual property, and reputational damage. The vulnerability's ability to execute arbitrary JavaScript in users' browsers could facilitate phishing attacks, session hijacking, or deployment of further malware within the corporate network. Since desknet's NEO is often used in multi-user environments, the risk of lateral movement and privilege escalation increases, potentially compromising broader organizational assets. The medium severity score reflects that while exploitation requires some authentication and user interaction, the consequences can still disrupt confidentiality and integrity of critical business processes. Additionally, compliance with GDPR and other data protection regulations may be jeopardized if personal data is exposed due to this vulnerability.
