CVE-2025-62911 identifies a stored cross-site scripting (XSS) vulnerability in Rock Content's Rock Convert product, versions up to 3.0.1. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be stored and subsequently executed in the browsers of users who access the affected pages. Stored XSS is particularly dangerous because the malicious payload persists on the server and can affect multiple users without requiring repeated attacker interaction. In this case, an attacker can inject JavaScript code that executes in the security context of the vulnerable application, potentially stealing session cookies, performing actions on behalf of users, or delivering further malware. The vulnerability does not require authentication, increasing its risk profile, and no user interaction beyond visiting a compromised page is necessary to trigger the exploit. Although no public exploits have been reported yet, the nature of stored XSS vulnerabilities makes them attractive targets for attackers aiming to compromise web applications with user-facing interfaces. Rock Convert is a content conversion and marketing automation tool, often used by organizations to manage and convert digital content. The vulnerability affects all versions up to and including 3.0.1, with no patch currently available or linked, indicating the need for vendor action. The lack of a CVSS score suggests this is a newly disclosed issue, but the technical details and attack vector indicate a significant risk. The vulnerability impacts confidentiality and integrity primarily, with potential availability impacts if attackers use the XSS to conduct further attacks such as defacement or injection of denial-of-service scripts. The scope includes all users of the affected Rock Convert instances, potentially spanning multiple organizations and industries. Given the web-based nature of the product, the attack surface is broad, and the ease of exploitation is high due to no authentication or complex prerequisites. This vulnerability requires immediate attention from organizations using Rock Convert to prevent exploitation and protect user data.

For European organizations, the impact of CVE-2025-62911 can be substantial. Stored XSS vulnerabilities can lead to unauthorized access to sensitive information such as session tokens, personal data, and credentials, violating GDPR and other data protection regulations prevalent in Europe. Exploitation could enable attackers to impersonate legitimate users, escalate privileges, or manipulate content, damaging organizational reputation and customer trust. Marketing and content management platforms like Rock Convert often integrate with other systems, increasing the risk of lateral movement or broader compromise. Additionally, successful attacks could result in regulatory fines and legal consequences due to data breaches. The persistent nature of stored XSS means multiple users can be affected over time, amplifying the potential damage. Organizations relying on Rock Convert for digital marketing campaigns or content conversion may face operational disruptions if the vulnerability is exploited to deface content or inject malicious scripts. The threat also poses risks to end customers and partners interacting with affected web interfaces, potentially leading to wider ecosystem compromise. Overall, the vulnerability threatens confidentiality, integrity, and to a lesser extent availability, with significant compliance and reputational risks for European entities.

1. Monitor Rock Content vendor communications closely for official patches addressing CVE-2025-62911 and apply updates immediately upon release. 2. In the interim, implement strict input validation and output encoding on all user-supplied data within Rock Convert instances to prevent malicious script injection. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS payloads. 4. Conduct thorough code reviews and security testing focused on input handling and output generation in Rock Convert customizations or integrations. 5. Limit user privileges and access controls within Rock Convert to reduce the potential damage from compromised accounts. 6. Educate users and administrators about the risks of XSS and encourage vigilance for suspicious activity or unexpected content changes. 7. Utilize web application firewalls (WAFs) with updated rules to detect and block common XSS attack patterns targeting Rock Convert. 8. Regularly audit logs for signs of exploitation attempts or anomalous behavior related to web content generation. 9. Consider isolating Rock Convert instances or restricting access to trusted networks until the vulnerability is remediated. 10. Coordinate incident response plans to quickly address any detected exploitation and minimize impact.
