CVE-2025-49052 is a Missing Authorization vulnerability (CWE-862) identified in the Dariolee Netease Music application, affecting versions up to 3.2.1. This vulnerability arises due to incorrectly configured access control security levels, allowing users with limited privileges (requiring some level of authentication but no user interaction) to perform actions or access resources beyond their authorization scope. The CVSS 3.1 base score is 4.3 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), no confidentiality impact (C:N), low integrity impact (I:L), and no availability impact (A:N). Essentially, an authenticated user with limited privileges can exploit this flaw remotely to perform unauthorized modifications or actions that affect the integrity of the system or data, but cannot access confidential information or disrupt availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant because missing authorization checks can lead to privilege escalation or unauthorized data manipulation, undermining trust in the application and potentially exposing users or backend systems to further attacks if leveraged in a chained exploit. The lack of user interaction requirement and network accessibility increases the risk of exploitation in environments where the application is deployed.

For European organizations using Dariolee Netease Music, this vulnerability could lead to unauthorized modification of user data or application state by authenticated users with limited privileges. While confidentiality is not directly impacted, integrity violations can affect user trust, data accuracy, and potentially lead to further security issues if attackers manipulate application behavior or escalate privileges. Organizations relying on this software for internal or customer-facing services may face reputational damage, compliance risks under GDPR if personal data integrity is compromised, and operational disruptions if the application is critical to business processes. The medium severity score suggests a moderate risk, but the ease of exploitation (low complexity, no user interaction) means attackers with valid credentials could exploit it remotely, which is a realistic threat scenario. European companies with large user bases or integrated systems involving Netease Music should be particularly cautious, as exploitation could propagate through connected systems or services.

Given the absence of a published patch, European organizations should implement compensating controls immediately. These include: 1) Restricting access to the Netease Music application to trusted networks and users only, minimizing exposure to potentially malicious authenticated users. 2) Enforcing strict user privilege management and regularly auditing user roles to ensure minimal necessary permissions are granted. 3) Monitoring application logs and user activities for unusual or unauthorized actions indicative of exploitation attempts. 4) Applying network-level controls such as web application firewalls (WAFs) to detect and block suspicious requests targeting authorization flaws. 5) Engaging with the vendor (Dariolee) for timely patch releases and applying updates promptly once available. 6) Conducting internal security assessments or penetration tests focused on access control mechanisms within the application to identify and remediate similar weaknesses proactively. 7) Educating users about the importance of credential security to prevent attackers from gaining authenticated access.
