CVE-2025-24833: Cross-site scripting (XSS) in NEOJAPAN Inc. desknet's NEO
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.
AI Analysis
Technical Summary
CVE-2025-24833 is a stored cross-site scripting (XSS) vulnerability identified in NEOJAPAN Inc.'s desknet's NEO product, affecting versions from V4.0R1.0 through V9.0R2.0. Stored XSS vulnerabilities occur when malicious scripts are permanently stored on the target server, such as in databases or message boards, and then served to users. In this case, an authenticated user with limited privileges can inject arbitrary JavaScript code into the application, which is then executed in the browsers of other users who access the affected content. This can lead to session hijacking, theft of sensitive information, or unauthorized actions performed on behalf of the victim user. The vulnerability requires the attacker to have some level of privileges (PR:L) and user interaction (UI:R), meaning the victim must interact with the malicious content for exploitation to occur. The CVSS vector indicates network attack vector (AV:N), low attack complexity (AC:L), and a scope change (S:C), meaning the vulnerability can affect resources beyond the initially compromised component. The impact on confidentiality and integrity is limited (C:L, I:L), with no impact on availability (A:N). No known exploits are currently reported in the wild, but the vulnerability is publicly disclosed and should be addressed promptly. The lack of a patch link suggests that fixes may be pending or need to be obtained directly from the vendor. The vulnerability is relevant for organizations using desknet's NEO, a groupware and collaboration platform widely used in enterprise environments, especially in Japan and increasingly in Europe. Attackers exploiting this vulnerability could leverage it to escalate privileges or move laterally within an organization by compromising user sessions or stealing credentials.
Potential 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.
Mitigation Recommendations
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.
