CVE-2025-41000 in BoomCMS
Summary
by MITRE • 09/03/2025
Cross-Frame Scripting (XFS) vulnerability in BoomCMS v9.1.4 from UXB London. XFS is a web attack technique that exploits specific browser bugs to spy on users via JavaScript. This type of attack is based on social engineering and depends entirely on the browser chosen by the user, so it is perceived as a minor threat to web application security. This vulnerability only works in older browsers.

The Cross-Frame Scripting vulnerability identified as CVE-2025-41000 represents a specific security flaw within BoomCMS version 9.1.4, developed by UXB London. This vulnerability falls under the broader category of web application security weaknesses that exploit browser implementation details rather than application logic flaws. The vulnerability specifically targets the interaction between frames and scripts within web browsers, creating potential attack vectors that could compromise user privacy and security. Such vulnerabilities are particularly concerning because they leverage fundamental browser behaviors that users may not be aware of, making them difficult to detect and prevent through conventional security measures.
Cross-Frame Scripting attacks exploit the way browsers handle frame navigation and script execution across different document contexts. The technical flaw in BoomCMS v9.1.4 stems from inadequate protection mechanisms that fail to properly isolate frame boundaries when processing user-generated content or external scripts. This vulnerability operates by manipulating the browser's frame hierarchy to execute malicious scripts in contexts where they would normally be restricted. The implementation relies on specific browser behaviors that were more prevalent in older browser versions, where security boundaries between frames were less strictly enforced. This architectural weakness allows attackers to potentially access sensitive information or manipulate user sessions through carefully crafted cross-frame scripting attacks.
The operational impact of this vulnerability is significant despite being classified as a minor threat due to its browser dependency requirements. Attackers can exploit this vulnerability to perform session hijacking, credential theft, or data exfiltration when users interact with compromised BoomCMS instances in vulnerable browser environments. The attack requires users to navigate to specific pages within the CMS where the vulnerability can be triggered, making it more of a targeted attack rather than a widespread exploit. However, the potential for social engineering campaigns to lure users into triggering these attacks makes the threat more pronounced. The vulnerability's effectiveness is directly tied to the browser version being used, which limits its scope but does not eliminate the risk entirely.
Mitigation strategies for CVE-2025-41000 should focus on both immediate remediation and long-term security improvements. The primary solution involves updating BoomCMS to versions that address this specific vulnerability, ensuring proper frame isolation mechanisms are implemented, and implementing Content Security Policy headers to prevent unauthorized frame interactions. Security teams should also consider browser compatibility testing to identify and address similar issues in older browser versions. The vulnerability aligns with CWE-79 Cross-Frame Scripting, which specifically addresses weaknesses in web applications that allow cross-frame scripting attacks. Organizations should implement monitoring systems to detect potential exploitation attempts and establish incident response procedures for handling such vulnerabilities. Additionally, user education about browser security features and the importance of keeping browsers updated can help reduce the attack surface. The remediation process should include comprehensive testing to ensure that frame boundary protections are properly enforced and that no other similar vulnerabilities exist within the application's codebase. This vulnerability demonstrates the importance of maintaining current security practices and understanding how browser-specific behaviors can create unexpected security risks in web applications.
