CVE-2025-8308 is an XSS vulnerability classified under CWE-79 that affects the INFOREX General Information Management System developed by Key Software Solutions Inc. The flaw stems from improper neutralization of input during web page generation, specifically through HTTP headers, which allows attackers to inject malicious scripts. This vulnerability affects all versions up to and including 2025, with the issue publicly disclosed in February 2026. The vulnerability can be exploited remotely without authentication (AV:N/AC:L/PR:N), but requires user interaction (UI:R), such as clicking a malicious link or visiting a compromised website that sends crafted HTTP headers to the vulnerable system. Successful exploitation could lead to the execution of arbitrary JavaScript in the context of the victim’s browser, potentially allowing theft of session cookies, redirection to malicious sites, or manipulation of displayed content. The CVSS v3.1 base score is 6.3, reflecting a medium severity level due to the combination of low attack complexity and user interaction requirement. The vendor has not responded to disclosure attempts, and no patches or known exploits have been reported. The vulnerability’s root cause is insufficient sanitization or encoding of HTTP header inputs before rendering them in web pages, which is a common vector for reflected or stored XSS attacks. Given the nature of the product—a general information management system—this vulnerability could be leveraged to target sensitive organizational data or user sessions if exploited in a real-world scenario.

For European organizations, exploitation of CVE-2025-8308 could compromise the confidentiality, integrity, and availability of sensitive information managed within the INFOREX system. Attackers could hijack user sessions, steal credentials, or manipulate displayed data, potentially leading to unauthorized access or data leakage. This is particularly concerning for organizations handling personal data under GDPR, as breaches could result in regulatory penalties and reputational damage. The requirement for user interaction limits automated exploitation but does not eliminate risk, especially in environments where phishing or social engineering is prevalent. The lack of vendor response and absence of patches increase exposure time, raising the likelihood of future exploitation. Organizations relying on INFOREX for critical information management may face operational disruptions if attackers leverage this vulnerability to inject malicious scripts that disrupt normal workflows or propagate malware. The impact is amplified in sectors such as government, finance, healthcare, and critical infrastructure where INFOREX might be deployed to manage sensitive or regulated data.

Since no official patches are available, European organizations should implement immediate compensating controls. First, apply strict input validation and sanitization on all HTTP headers processed by the INFOREX system, ensuring that any user-controllable input is properly encoded before rendering in web pages. Deploy a robust Content Security Policy (CSP) to restrict execution of unauthorized scripts and reduce the impact of potential XSS payloads. Use web application firewalls (WAFs) configured to detect and block suspicious HTTP headers or XSS attack patterns targeting the application. Educate users about the risks of clicking untrusted links or opening suspicious emails to reduce the likelihood of successful user interaction exploitation. Monitor logs and network traffic for unusual HTTP header values or anomalous behavior indicative of attempted exploitation. Consider isolating the INFOREX system within segmented network zones to limit lateral movement if compromised. Finally, maintain regular backups and incident response plans tailored to web application attacks to ensure rapid recovery if exploitation occurs.
