CVE-2025-62911 identifies a Stored Cross-Site Scripting (XSS) vulnerability in Rock Content's Rock Convert product, affecting all versions up to and including 3.0.1. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows an attacker to inject malicious scripts that are stored and later executed in the context of other users' browsers. The CVSS 3.1 vector indicates the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), but requires low privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality and integrity partially (C:L/I:L) but does not affect availability (A:N). Stored XSS can be leveraged to hijack user sessions, steal cookies, perform actions on behalf of users, or deliver further malware payloads. No patches or known exploits are currently reported, but the vulnerability is publicly disclosed and should be addressed promptly. Rock Convert is a content conversion and marketing tool, often integrated into digital marketing workflows, making it a potential target for attackers seeking to compromise marketing platforms or customer data.

For European organizations, this vulnerability poses a risk primarily to the confidentiality and integrity of user data and session information within Rock Convert deployments. Attackers exploiting this flaw could execute arbitrary scripts in the context of authenticated users, potentially leading to unauthorized actions, data leakage, or further compromise of internal systems. Organizations relying on Rock Convert for marketing automation or content conversion may face reputational damage and regulatory compliance issues, especially under GDPR, if personal data is exposed. The requirement for user interaction and low privilege reduces the ease of exploitation but does not eliminate risk, particularly in environments with many users or where social engineering can be employed. The absence of availability impact means service disruption is unlikely, but the integrity and confidentiality risks remain significant. European companies integrating Rock Convert into their digital ecosystems should consider this vulnerability a moderate threat that could facilitate broader attacks if chained with other vulnerabilities or social engineering tactics.

Organizations should monitor Rock Content's official channels for patches addressing CVE-2025-62911 and apply updates promptly once available. In the interim, implement strict input validation and sanitization on all user inputs within Rock Convert interfaces to prevent malicious script injection. Deploy Content Security Policies (CSP) to restrict the execution of unauthorized scripts and reduce the impact of potential XSS payloads. Conduct regular security awareness training to reduce the likelihood of successful social engineering that could trigger user interaction required for exploitation. Review and limit user privileges within Rock Convert to the minimum necessary to reduce the attack surface. Employ web application firewalls (WAFs) with rules tuned to detect and block XSS attempts targeting Rock Convert endpoints. Additionally, monitor logs and user activity for unusual behavior that may indicate exploitation attempts. Consider isolating Rock Convert instances or restricting access to trusted networks to further reduce exposure.
