CVE-2025-47458 is a high-severity reflected Cross-site Scripting (XSS) vulnerability identified in B2itech's B2i Investor Tools, affecting versions up to 1.0.7.9. This vulnerability arises from improper neutralization of input during web page generation (CWE-79), allowing an attacker to inject malicious scripts into web pages viewed by other users. Specifically, the flaw permits the injection of arbitrary JavaScript code that is reflected back in the HTTP response without adequate sanitization or encoding. The vulnerability is exploitable remotely over the network without requiring authentication (AV:N/PR:N), but requires user interaction (UI:R), such as clicking a crafted link. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component, potentially impacting confidentiality, integrity, and availability. The CVSS 3.1 base score of 7.1 reflects a high severity, with partial impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the potential for session hijacking, credential theft, defacement, or redirection to malicious sites. B2i Investor Tools is a financial software product used for investor relations and financial data management, which may handle sensitive financial information and user credentials, increasing the risk profile of this vulnerability.

For European organizations using B2i Investor Tools, this vulnerability could lead to unauthorized access to sensitive financial data, manipulation of investor information, and compromise of user sessions. The reflected XSS can be leveraged by attackers to steal authentication tokens or perform actions on behalf of legitimate users, potentially resulting in financial fraud, reputational damage, and regulatory non-compliance under GDPR due to data breaches. Financial institutions, investment firms, and corporate investor relations departments are particularly at risk. The vulnerability's ability to affect confidentiality, integrity, and availability means attackers could disrupt business operations or manipulate critical financial disclosures. Given the interconnected nature of financial markets in Europe, exploitation could have cascading effects on stakeholders and partners. The requirement for user interaction means phishing or social engineering campaigns could be used to exploit this vulnerability, increasing the attack surface.

Organizations should prioritize updating B2i Investor Tools to a patched version once available. In the absence of an official patch, implement strict input validation and output encoding on all user-supplied data reflected in web pages, using context-aware encoding libraries to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. Conduct regular security assessments and penetration testing focused on web application input handling. Educate users to recognize phishing attempts that may exploit this vulnerability. Additionally, implement Web Application Firewalls (WAFs) with rules to detect and block reflected XSS payloads targeting B2i Investor Tools endpoints. Monitor logs for suspicious activity indicative of attempted exploitation. Finally, ensure incident response plans include procedures for handling XSS-related breaches, including session invalidation and user notification.
