CVE-2025-63004 is a missing authorization vulnerability categorized under CWE-862, found in Skynet Technologies USA LLC's All in One Accessibility product, affecting versions up to 1.14. The vulnerability stems from improperly configured access control mechanisms that fail to enforce correct authorization checks on certain functions or resources. This misconfiguration allows users with limited privileges (PR:L) to perform actions beyond their intended permissions, potentially altering data or system states without proper authorization. The vulnerability does not require user interaction (UI:N) and can be exploited remotely (AV:N), increasing its risk profile. However, it does not impact confidentiality or availability, focusing primarily on integrity violations. The CVSS 3.1 vector (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) indicates that the attack complexity is low, and the scope remains unchanged. No patches or known exploits are currently available, suggesting that organizations should proactively assess and remediate access control configurations. The All in One Accessibility product is typically used to enhance accessibility features, implying its deployment in environments requiring compliance with accessibility standards, including public sector and enterprise environments.

For European organizations, the primary impact of CVE-2025-63004 lies in the potential unauthorized modification of data or system configurations within the All in One Accessibility product. This could lead to integrity issues, such as unauthorized changes to accessibility settings or user data, potentially undermining compliance with accessibility regulations like the EU Web Accessibility Directive. Although confidentiality and availability are not directly affected, integrity violations can disrupt operational workflows and damage trust in accessibility tools. Organizations in sectors with stringent regulatory requirements, such as government agencies, healthcare, and education, may face increased risks. Additionally, unauthorized modifications could be leveraged as a foothold for further attacks if combined with other vulnerabilities. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often target misconfigurations in access controls. The medium severity rating reflects a moderate risk that should be addressed promptly to avoid escalation.

To mitigate CVE-2025-63004, European organizations should undertake a thorough review of access control policies and configurations within the All in One Accessibility product. Specifically, they should: 1) Implement strict role-based access control (RBAC) ensuring that users have only the minimum necessary privileges; 2) Audit and validate all authorization checks to confirm that sensitive functions cannot be accessed by unauthorized users; 3) Monitor logs for unusual privilege escalations or unauthorized access attempts related to accessibility features; 4) Engage with Skynet Technologies for updates or patches and apply them promptly once available; 5) Conduct penetration testing focused on access control weaknesses in the product; 6) Train administrators and users on secure configuration practices and the importance of access controls; 7) Where possible, isolate the accessibility tool within segmented network zones to limit potential lateral movement; 8) Maintain up-to-date inventories of affected software versions to ensure timely identification of vulnerable instances. These targeted actions go beyond generic advice by focusing on access control hardening and proactive monitoring specific to this vulnerability.
