CVE-2025-48097 is a reflected Cross-site Scripting (XSS) vulnerability found in Shiva WSAnalytics, a web analytics and dashboard product, affecting versions up to 1.1.2. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows attackers to inject malicious JavaScript code into web pages viewed by other users. When a victim interacts with a crafted URL or input, the malicious script executes in their browser context, potentially leading to session hijacking, theft of sensitive information, or unauthorized actions performed on behalf of the user. The vulnerability is exploitable remotely over the network without requiring authentication (AV:N, PR:N), but does require user interaction (UI:R), such as clicking a malicious link. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The CVSS v3.1 base score is 7.1, reflecting high severity with impacts on confidentiality, integrity, and availability (C:L/I:L/A:L). No public exploits are currently known, but the vulnerability is publicly disclosed and should be addressed promptly. WSAnalytics is used for integrating Google Analytics data and dashboards, making it a valuable target for attackers seeking to compromise analytics data or user sessions. The absence of a patch link suggests that a fix may not yet be available, emphasizing the need for interim mitigations.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of analytics data and user sessions. Attackers exploiting this XSS flaw can hijack user sessions, steal authentication tokens, or perform unauthorized actions within the analytics platform, potentially leading to data leakage or manipulation of business intelligence data. This can undermine decision-making processes and expose sensitive operational insights. Additionally, the availability of the service could be impacted if attackers use the vulnerability to execute denial-of-service attacks or inject disruptive scripts. Organizations relying heavily on WSAnalytics for monitoring web traffic and performance may experience operational disruptions. Given the interconnected nature of European digital infrastructure and strict data protection regulations such as GDPR, exploitation could also lead to regulatory penalties and reputational damage. The requirement for user interaction means phishing or social engineering campaigns could be used to trigger exploitation, increasing the attack surface.

1. Immediately monitor for any updates or patches from Shiva and apply them as soon as they become available. 2. Implement strict input validation and output encoding on all user-supplied data within WSAnalytics to neutralize malicious scripts. 3. Deploy a robust Content Security Policy (CSP) to restrict the execution of unauthorized scripts and reduce XSS impact. 4. Use web application firewalls (WAFs) with rules designed to detect and block reflected XSS attempts targeting WSAnalytics endpoints. 5. Conduct user awareness training to educate employees about the risks of clicking on suspicious links or interacting with untrusted inputs. 6. Review and harden authentication and session management mechanisms to limit the impact of session hijacking. 7. Isolate WSAnalytics instances within segmented network zones to minimize lateral movement if compromised. 8. Regularly audit logs and monitor for unusual activity indicative of exploitation attempts. 9. Consider temporary disabling or restricting access to vulnerable WSAnalytics features until a patch is available. 10. Engage in threat intelligence sharing with industry peers to stay informed about emerging exploitation techniques.
