The vulnerability CVE-2024-9174 represents a stored HTML injection flaw within the social module of M-Files Hubshare platform prior to version 5.0.8.6. This security weakness resides in the application's handling of user-generated content within the social collaboration features, specifically affecting how the system processes and displays HTML content submitted by authenticated users. The issue stems from insufficient input validation and output encoding mechanisms that fail to properly sanitize user-supplied HTML content before storing and rendering it within the user interface. Attackers can exploit this vulnerability by submitting malicious HTML code through social module functionalities such as comments, posts, or profile descriptions, which then gets stored in the application's database and subsequently rendered to other users who view the affected content. This stored nature of the vulnerability means that the malicious payload persists even after the initial submission, making it particularly dangerous as it can affect multiple users over extended periods without requiring repeated exploitation attempts.
The technical execution of this vulnerability involves an authenticated user leveraging their legitimate access privileges to inject malicious HTML code into the social module's content fields. When other users navigate to pages containing this stored content, the injected HTML executes within their browser context, potentially enabling various attack vectors including cross-site scripting attacks, session hijacking, or user interface spoofing. The vulnerability directly maps to CWE-79 - Cross-site Scripting (XSS) and specifically relates to stored XSS attacks where malicious code is permanently stored on the target server and automatically executed when users access the affected content. The impact extends beyond simple script execution as the injected HTML can manipulate the user interface elements, potentially redirecting users to malicious sites, stealing cookies, or performing unauthorized actions on behalf of the victim. This type of vulnerability can significantly compromise user trust and platform integrity, as users may unknowingly interact with malicious content that appears legitimate within the application's social features.
The operational impact of CVE-2024-9174 is substantial for organizations relying on M-Files Hubshare for collaborative document management and social features. The ability to spoof user interface elements through stored HTML injection creates opportunities for social engineering attacks that can deceive users into revealing sensitive information or performing unintended actions. Attackers can craft malicious content that appears to originate from trusted sources within the platform, making detection and mitigation more challenging. The vulnerability affects the platform's security posture by undermining the trust model that users place in the social collaboration features, potentially leading to unauthorized access to sensitive documents, data exfiltration, or reputation damage. Organizations may experience cascading effects where compromised user sessions lead to broader access violations within the document management system. The persistent nature of stored XSS vulnerabilities means that the impact can compound over time as more users encounter the malicious content, potentially affecting numerous users across different departments or organizational levels. This vulnerability also violates security principles outlined in the OWASP Top Ten 2021, specifically addressing injection flaws and insecure design practices that enable attackers to manipulate application behavior through user input.
Mitigation strategies for CVE-2024-9174 require immediate implementation of proper input validation and output encoding mechanisms within the social module. Organizations should upgrade to M-Files Hubshare version 5.0.8.6 or later, which includes the necessary security patches addressing this vulnerability. The fix should implement comprehensive HTML sanitization that removes or encodes potentially dangerous HTML elements and attributes before storing user content. Additionally, organizations should implement Content Security Policy (CSP) headers to limit the execution of inline scripts and restrict the sources from which content can be loaded. Regular security scanning and monitoring of user-generated content within social features should be established to detect potential exploitation attempts. The implementation of proper access controls and user session management can help limit the scope of potential attacks, while security awareness training for users can help them identify suspicious social content. Organizations should also consider implementing web application firewalls that can detect and block known attack patterns associated with HTML injection attacks. These measures align with ATT&CK technique T1059.007 - Command and Scripting Interpreter: JavaScript and T1566.001 - Phishing: Spearphishing Attachment, as the vulnerability can be exploited to deliver malicious JavaScript payloads and deceive users through spoofed interface elements that appear legitimate within the platform's social environment.
