CVE-2025-47773 is a cross-site scripting (XSS) vulnerability identified in Combodo iTop, a widely used web-based IT service management tool. The vulnerability exists in versions prior to 2.7.13 and between 3.0.0-alpha and 3.2.2, where the application fails to properly neutralize user-supplied input during the generation of web pages, specifically when dashboards are edited via AJAX calls. This improper input sanitization allows attackers to inject malicious JavaScript code into the dashboard interface. When a legitimate user loads the compromised dashboard, the injected script executes in their browser context, potentially leading to session hijacking, credential theft, unauthorized actions, or deployment of further malware. The vulnerability does not require authentication but does require user interaction to trigger the malicious payload. The CVSS v3.1 base score of 8.8 reflects the vulnerability's high impact on confidentiality, integrity, and availability, combined with its low attack complexity and network attack vector. Although no exploits have been reported in the wild yet, the flaw's presence in commonly deployed versions of iTop makes it a significant threat. The vendor has addressed the issue in versions 2.7.13 and 3.2.2 by properly sanitizing rendered HTML content, preventing script injection. Organizations running affected versions should urgently upgrade to these patched releases. The vulnerability aligns with CWE-79, highlighting the classic risk of improper input neutralization leading to XSS attacks in web applications.

For European organizations, the impact of CVE-2025-47773 can be substantial, especially for those relying on Combodo iTop for IT service management and operational workflows. Exploitation can lead to unauthorized access to sensitive ITSM data, manipulation of service records, and potential lateral movement within internal networks. Confidentiality breaches could expose internal service configurations and user credentials, while integrity violations might disrupt IT service processes or cause erroneous data to propagate. Availability could also be affected if attackers leverage the vulnerability to execute denial-of-service conditions or deploy ransomware. Given that iTop is often integrated with other enterprise systems, a successful attack could cascade, affecting broader organizational infrastructure. The vulnerability's remote exploitability without authentication increases risk, particularly in environments where dashboards are accessible to multiple users or external partners. European entities in sectors such as finance, healthcare, government, and critical infrastructure, which depend heavily on ITSM tools, face heightened risks of operational disruption and data compromise. Furthermore, regulatory frameworks like GDPR impose strict data protection requirements, and exploitation leading to data breaches could result in significant legal and financial penalties.

To mitigate CVE-2025-47773, organizations should immediately upgrade Combodo iTop installations to versions 2.7.13 or 3.2.2, where the vulnerability is patched. If immediate upgrading is not feasible, restrict dashboard editing privileges to trusted administrators only, minimizing the attack surface. Implement robust input validation and sanitization on all user-supplied data, especially in AJAX endpoints handling dashboard modifications. Deploy Content Security Policies (CSP) to limit the execution of unauthorized scripts in browsers. Monitor web application logs for unusual AJAX requests or suspicious dashboard edits that could indicate exploitation attempts. Conduct regular security assessments and penetration testing focused on web application vulnerabilities. Additionally, educate users about the risks of interacting with untrusted dashboards or links. Network segmentation and application-layer firewalls can further reduce exposure by limiting access to the iTop interface. Finally, maintain an incident response plan tailored to web application attacks to quickly detect and respond to potential exploitation.
