CVE-2025-9676 is a medium-severity vulnerability affecting the NCSOFT Universe App versions 1.0 through 1.3.0. The vulnerability arises from improper export of Android application components as defined in the app's AndroidManifest.xml file, specifically within the component com.ncsoft.universeapp. Improper export means that certain app components (such as activities, services, or broadcast receivers) are made accessible to other apps or processes without adequate access control. This can allow a local attacker with limited privileges (local access required) to interact with these components in unintended ways, potentially leading to unauthorized information disclosure, privilege escalation, or manipulation of app behavior. The vulnerability does not require user interaction and has a low complexity of attack, but it does require local access and limited privileges. The CVSS 4.0 vector indicates local attack vector (AV:L), low attack complexity (AC:L), no authentication required (AT:N), low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L), and no scope change. Although the vendor was contacted, no response or patch has been provided, and an exploit is publicly available, increasing the risk of exploitation. However, there are no known exploits in the wild at this time. The vulnerability is rooted in Android component export misconfiguration, a common source of privilege escalation and data leakage on Android platforms. Given the local access requirement, exploitation is limited to scenarios where an attacker already has some foothold on the device, such as through malicious apps or physical access.

For European organizations, the impact of CVE-2025-9676 depends largely on the deployment and usage of the NCSOFT Universe App within their environments. As the app is a mobile application, the primary risk is to employees or users who have the app installed on their Android devices. Exploitation could allow attackers with local access to escalate privileges or access sensitive app components, potentially leading to leakage of user data or unauthorized actions within the app context. This could compromise confidentiality and integrity of user data and potentially affect business operations if the app is used for corporate communications or services. The lack of vendor response and patch availability increases the window of exposure. Organizations with Bring Your Own Device (BYOD) policies or those in gaming, entertainment, or digital community sectors where NCSOFT apps are popular may face higher risk. Additionally, if attackers use this vulnerability as a pivot point on compromised devices, it could facilitate lateral movement or further compromise. However, the medium severity and local access requirement limit the threat to targeted attacks rather than widespread exploitation.

1. Immediate mitigation should focus on restricting local access to devices with the NCSOFT Universe App installed, including enforcing strong device authentication and limiting physical access. 2. Organizations should audit Android devices for the presence of the vulnerable app versions (1.0 to 1.3.0) and remove or restrict usage where possible. 3. Employ mobile device management (MDM) solutions to enforce app whitelisting and control app installation policies, preventing installation of vulnerable versions. 4. Monitor device logs and app behavior for unusual inter-process communication or unauthorized component access attempts. 5. Educate users about the risks of installing untrusted apps and the importance of device security hygiene. 6. Since no patch is available, consider sandboxing or containerizing the app environment to limit the impact of exploitation. 7. Stay alert for vendor updates or community patches and apply them promptly once available. 8. For organizations developing Android apps, review AndroidManifest.xml configurations to avoid improper component exports and follow the principle of least privilege.
