CVE-2024-47854 is a reflected Cross-Site Scripting (XSS) vulnerability identified in Veritas Data Insight versions before 7.1. The flaw arises because the application fails to properly sanitize user-supplied input in HTTP requests, allowing an attacker to inject arbitrary JavaScript code. When an authenticated user interacts with a maliciously crafted link or HTTP request containing this injected script, the script executes in the context of the user's browser session. This can lead to theft of session tokens, unauthorized actions performed on behalf of the user, or disclosure of sensitive information accessible through the application. The vulnerability does not require any authentication or privileges to exploit, but it does require user interaction, such as clicking a malicious link. The CVSS 3.1 base score of 6.1 reflects a medium severity, with attack vector being network-based, low attack complexity, no privileges required, and user interaction necessary. The scope is changed, indicating that exploitation could affect resources beyond the vulnerable component. No patches or exploits are currently publicly available, but the risk remains significant given the nature of the vulnerability and the sensitive data typically managed by Veritas Data Insight. The CWE-79 classification confirms this is a classic XSS issue, emphasizing the need for proper input validation and output encoding in web applications.

For European organizations, the impact of CVE-2024-47854 can be substantial, particularly for enterprises relying on Veritas Data Insight for data governance, compliance, and security analytics. Successful exploitation could allow attackers to hijack user sessions, steal sensitive data, or perform unauthorized actions within the application, potentially leading to data breaches or compliance violations under regulations such as GDPR. The reflected XSS nature means phishing or social engineering campaigns could be used to trick users into executing malicious scripts, increasing the risk of targeted attacks. Given that Veritas Data Insight is often deployed in environments handling critical enterprise data, the confidentiality and integrity of data could be compromised. Although availability impact is low, the reputational damage and regulatory penalties resulting from data exposure or misuse could be significant. The medium severity rating suggests that while the vulnerability is not trivially exploitable without user interaction, the potential consequences warrant prompt mitigation, especially in sectors with high compliance requirements such as finance, healthcare, and government within Europe.

European organizations should implement the following specific mitigations: 1) Monitor Veritas communications for official patches or updates addressing this vulnerability and prioritize timely deployment once available. 2) Until patches are released, apply Web Application Firewall (WAF) rules to detect and block suspicious input patterns indicative of XSS attacks targeting Veritas Data Insight. 3) Educate users about the risks of clicking unsolicited links and implement email filtering to reduce phishing attempts that could deliver malicious URLs exploiting this vulnerability. 4) Enforce strict Content Security Policies (CSP) on the application to restrict execution of unauthorized scripts. 5) Conduct regular security assessments and penetration testing focused on web application input validation and output encoding to identify and remediate similar issues proactively. 6) Review and harden authentication and session management controls to limit the impact of any session hijacking attempts. 7) Implement network segmentation and least privilege access controls around Veritas Data Insight deployments to reduce exposure. These targeted actions go beyond generic advice and address the specific attack vectors and environment of this vulnerability.
