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

European organizations should implement a multi-layered mitigation approach: 1) Apply any available patches or updates from NEOJAPAN Inc. as soon as they are released. 2) If patches are not yet available, implement strict input validation and output encoding on all user-supplied data fields within desknet's NEO to prevent script injection and execution. 3) Restrict user privileges to the minimum necessary, limiting the ability of low-privilege users to inject content that is rendered by others. 4) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing the application. 5) Conduct user awareness training to recognize suspicious behavior or unexpected prompts within the application. 6) Monitor logs and network traffic for unusual activity indicative of XSS exploitation attempts. 7) Consider deploying web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting desknet's NEO. 8) Regularly audit and review collaboration content for suspicious or unexpected scripts or markup. These steps go beyond generic advice by focusing on compensating controls and proactive detection in the absence of immediate patches.

Description

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

Impact

For European organizations, this vulnerability poses a moderate risk primarily to confidentiality and integrity of data handled within desknet's NEO. Attackers could leverage the stored XSS to hijack user sessions, steal credentials or sensitive information, and perform unauthorized actions under the guise of legitimate users. This is particularly concerning for organizations using desknet's NEO for internal communications, project management, or document sharing, as sensitive corporate or governmental data could be exposed. The requirement for user interaction and low privilege reduces the ease of exploitation but does not eliminate risk, especially in environments with many users and frequent collaboration. The medium CVSS score reflects this balanced risk. If exploited, attackers could gain footholds for further attacks or data exfiltration. European entities with regulatory obligations under GDPR must consider the potential data breach implications and associated compliance risks. The absence of known exploits currently reduces immediate threat but does not preclude future attacks.
