CVE-2024-6124 is a reflected cross-site scripting (XSS) vulnerability identified in M-Files Corporation's Hubshare product versions prior to 5.0.6.0. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. Specifically, the application fails to adequately sanitize user-supplied input before reflecting it back in the web page, enabling attackers to inject malicious JavaScript code. When a victim interacts with a crafted URL or input, the injected script executes within their browser context, potentially compromising session tokens, cookies, or enabling unauthorized actions. The CVSS 4.0 score of 8.5 reflects a high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:A). The vulnerability impacts confidentiality and integrity highly, as attackers can steal sensitive data or manipulate user sessions. No known exploits are currently reported in the wild, but the vulnerability is publicly disclosed and thus may be targeted soon. The issue affects all versions before 5.0.6.0, and no official patch links are provided yet, indicating the need for immediate attention. The vulnerability is particularly concerning for organizations relying on Hubshare for document sharing and collaboration, as XSS can lead to broader compromise within enterprise environments.

The exploitation of CVE-2024-6124 can have significant impacts on organizations globally. Successful attacks can lead to unauthorized disclosure of sensitive information, including session cookies and authentication tokens, enabling attackers to impersonate legitimate users. This can result in data breaches, unauthorized access to confidential documents, and potential lateral movement within corporate networks. Additionally, attackers can perform actions on behalf of users, such as changing settings or exfiltrating data, undermining data integrity. The reflected XSS nature means phishing or social engineering campaigns can be used to lure victims into clicking malicious links, increasing the attack surface. Organizations using Hubshare for critical document management and collaboration are at risk of operational disruption and reputational damage. The absence of known exploits currently provides a window for proactive mitigation, but the public disclosure increases the likelihood of exploitation attempts. The impact is amplified in sectors with high confidentiality requirements, such as finance, healthcare, and government.

To mitigate CVE-2024-6124, organizations should prioritize upgrading M-Files Hubshare to version 5.0.6.0 or later once available. In the interim, implement strict input validation and output encoding on all user-supplied data reflected in web pages to prevent injection of malicious scripts. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS payloads. Educate users to recognize and avoid clicking suspicious links, especially those received via email or messaging platforms. Employ web application firewalls (WAFs) with rules tailored to detect and block reflected XSS attempts targeting Hubshare endpoints. Regularly audit and monitor web traffic for unusual patterns indicative of exploitation attempts. Coordinate with M-Files support for any available patches or workarounds and maintain an incident response plan to quickly address any detected compromise. Additionally, consider isolating Hubshare access within secure network segments to limit exposure.
