CVE-2025-15124 is a security vulnerability identified in JeecgBoot, an open-source rapid development platform, affecting all versions up to 3.9.0. The flaw exists in the getParameterMap function within the /sys/sysDepartPermission/list endpoint, where improper authorization allows an attacker to manipulate the 'departId' parameter. This manipulation can bypass intended access controls, potentially granting unauthorized access to department-related permission data or functions. The vulnerability can be exploited remotely without user interaction, but requires low privileges and has a high attack complexity, indicating that exploitation demands significant effort or specific conditions. The CVSS 4.0 base score is 2.3, reflecting low severity primarily due to limited confidentiality impact and the difficulty of exploitation. No authentication is strictly required, but the attacker must have some level of access (PR:L). The vendor was notified but did not respond, and no official patch or mitigation has been published. Although a public exploit is available, there are no confirmed reports of exploitation in the wild. This vulnerability highlights a weakness in authorization logic that could be leveraged to escalate privileges or access restricted data within affected JeecgBoot deployments.

For European organizations using JeecgBoot, particularly those relying on it for internal permission and department management, this vulnerability could allow unauthorized access to sensitive organizational data or functions. While the direct impact on confidentiality and integrity is limited due to the high complexity and low exploitability, unauthorized access could lead to information disclosure or privilege escalation within the application context. This could affect internal workflows, data segregation, and compliance with data protection regulations such as GDPR if sensitive personal or organizational data is exposed. The lack of vendor response and patches increases risk exposure duration. However, the low CVSS score and absence of known active exploitation reduce immediate risk. Organizations in sectors with strict access control requirements or those using JeecgBoot in critical environments should consider this vulnerability a potential risk to internal security posture.

Since no official patch is available, European organizations should implement compensating controls immediately. These include: 1) Restricting network access to the affected endpoint (/sys/sysDepartPermission/list) via firewall rules or API gateways to trusted users only. 2) Implementing additional authorization checks at the application or proxy level to validate departId parameters against user privileges. 3) Conducting thorough access reviews and audits of permissions within JeecgBoot to detect anomalies. 4) Monitoring logs for unusual access patterns or parameter manipulations targeting departId. 5) Isolating or segmenting JeecgBoot deployments to limit lateral movement if exploited. 6) Preparing for rapid patch deployment once the vendor releases an official fix or community patches become available. 7) Educating development and security teams about this vulnerability to ensure awareness and readiness. These targeted mitigations go beyond generic advice by focusing on access control hardening and monitoring specific to the vulnerability's exploitation vector.
