CVE-2025-48097 is a reflected Cross-site Scripting (XSS) vulnerability identified in Shiva's WSAnalytics product, specifically affecting versions up to and including 1.1.2. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows attackers to inject malicious JavaScript code that is reflected back to the victim's browser. When a user interacts with a crafted URL or input, the malicious script executes in the context of the victim's session, potentially leading to session hijacking, theft of sensitive information, or manipulation of the web application's behavior. The vulnerability does not require any privileges (AV:N), has low attack complexity (AC:L), and requires user interaction (UI:R), with a scope change (S:C) indicating that the vulnerability can affect resources beyond the vulnerable component. The impact affects confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L). No patches or official fixes have been released yet, and no known exploits have been observed in the wild. The vulnerability was reserved in May 2025 and published in October 2025. WSAnalytics is a web analytics and dashboard tool, often used to integrate Google Analytics data, making it a valuable target for attackers seeking to compromise analytics data or user sessions. The reflected XSS nature means attackers typically use social engineering to lure users into clicking malicious links. The vulnerability's presence in a widely used analytics tool increases the risk of exploitation in environments relying on WSAnalytics for business intelligence and monitoring.

For European organizations, this vulnerability poses significant risks to the confidentiality and integrity of analytics data and user sessions. Attackers exploiting this XSS flaw can hijack user sessions, steal authentication tokens, or manipulate displayed data, potentially leading to unauthorized access or misinformation. This can disrupt decision-making processes reliant on analytics dashboards and damage organizational reputation. Additionally, the vulnerability could serve as a pivot point for further attacks within corporate networks, especially if WSAnalytics is integrated with other internal systems. The requirement for user interaction means phishing or social engineering campaigns could be used to exploit the vulnerability, increasing risk in sectors with high user engagement such as finance, healthcare, and government. The availability impact, while limited, could result in denial of service through script-based attacks or browser crashes. Since no patches are currently available, organizations face a window of exposure until mitigations or updates are deployed.

1. Implement strict input validation and output encoding on all user-supplied data within WSAnalytics to neutralize malicious scripts before rendering. 2. Deploy Web Application Firewalls (WAFs) with updated rules to detect and block reflected XSS attack patterns targeting WSAnalytics endpoints. 3. Educate users on the risks of clicking untrusted links, especially those purporting to lead to analytics dashboards or reports. 4. Monitor logs and network traffic for unusual requests or patterns indicative of XSS exploitation attempts. 5. Isolate WSAnalytics instances from critical internal systems to limit potential lateral movement if compromised. 6. Engage with Shiva for timely patches or updates and plan for rapid deployment once available. 7. Consider implementing Content Security Policy (CSP) headers to restrict script execution sources and reduce impact of injected scripts. 8. Conduct regular security assessments and penetration tests focusing on web application input handling and XSS vulnerabilities.
