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 2026-10-26.

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

1. Apply vendor-provided patches or updates for desknet's NEO as soon as they become available to remediate the vulnerability. 2. Implement strict input validation and sanitization on all user-supplied data to prevent injection of malicious scripts. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the application context. 4. Limit user privileges following the principle of least privilege to reduce the risk of exploitation by low-privilege users. 5. Educate users about the risks of interacting with unexpected or suspicious content within the platform. 6. Monitor application logs and user activity for unusual behavior that could indicate exploitation attempts. 7. Consider deploying web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting desknet's NEO. 8. Regularly review and update security configurations and conduct penetration testing focused on XSS vulnerabilities. 9. Segment the network to contain potential lateral movement if an account is compromised. 10. Maintain an incident response plan that includes procedures for handling XSS exploitation scenarios.

Description

Stored cross-site scripting (XSS) vulnerability in desknet's NEO versions V4.0R1.0–V9.0R2.0 allow execution of arbitrary JavaScript in a user’s web browser.

Impact

For European organizations, the impact of CVE-2025-24833 can be significant, particularly for those relying on desknet's NEO for internal communication and collaboration. Successful exploitation could lead to unauthorized access to sensitive corporate data, session hijacking, and potential lateral movement within the network. This could compromise confidentiality and integrity of business-critical information. While availability is not directly impacted, the indirect consequences of data breaches or unauthorized actions could disrupt business operations and damage organizational reputation. Additionally, the requirement for user interaction and some privileges limits the attack surface but does not eliminate risk, especially in environments with many users and varying privilege levels. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, may face compliance risks if the vulnerability is exploited. The absence of known exploits in the wild currently reduces immediate risk but should not lead to complacency. The collaborative nature of desknet's NEO means that compromised accounts could be used to spread malicious content internally, amplifying the threat.
