CVE-2025-15122 is a security vulnerability identified in JeecgBoot, an open-source rapid development platform widely used for enterprise applications. The vulnerability resides in the loadDatarule function within the /sys/sysDepartRole/datarule/ path, where improper authorization checks allow an attacker to manipulate the departId and roleId parameters. This manipulation can bypass intended access controls, potentially granting unauthorized access to data or functionality tied to specific departments or roles. The vulnerability is remotely exploitable without user interaction, but requires low privileges and has a high attack complexity, making exploitation challenging. The CVSS 4.0 vector indicates network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:L), no user interaction (UI:N), and low impact on confidentiality (VC:L), with no impact on integrity or availability. Despite the existence of a public exploit, no known active exploitation in the wild has been reported. The vendor has not issued any patches or responded to the disclosure, leaving affected versions 3.0 through 3.9.0 vulnerable. This vulnerability could allow attackers to gain unauthorized access to sensitive data or perform unauthorized actions within the application context, depending on the role and department data accessed. Given the lack of vendor response, organizations must rely on detection and mitigation strategies until official patches are released.

For European organizations using JeecgBoot, this vulnerability poses a risk of unauthorized access to sensitive departmental or role-based data, potentially leading to data leakage or privilege escalation within the application. Although the impact on confidentiality is low and integrity and availability are unaffected, unauthorized data access could violate data protection regulations such as GDPR if personal or sensitive information is exposed. The high complexity and low exploitability reduce the likelihood of widespread attacks, but targeted attackers with some level of access could exploit this flaw to gain unauthorized insights or perform unauthorized operations. The absence of vendor patches increases the risk exposure duration. Organizations in sectors with strict compliance requirements or handling sensitive data should be particularly cautious. The risk is compounded if JeecgBoot is integrated into critical business processes or internal management systems, where unauthorized access could disrupt operations or lead to reputational damage.

Since no official patches are currently available, European organizations should implement compensating controls to mitigate the risk. These include: 1) Restrict network access to the affected endpoints by implementing strict firewall rules and network segmentation to limit exposure to trusted users only. 2) Enforce strong authentication and authorization policies at the application and infrastructure levels to reduce the risk of low-privilege attackers exploiting the vulnerability. 3) Monitor and log access to the /sys/sysDepartRole/datarule/ endpoint for unusual or unauthorized parameter manipulations, enabling early detection of exploitation attempts. 4) Conduct code reviews and consider implementing custom authorization checks or input validation on departId and roleId parameters as an interim fix. 5) Educate development and security teams about this vulnerability to raise awareness and prepare for patch deployment once available. 6) Engage with the JeecgBoot community or maintainers to track updates and advocate for timely patch releases. 7) Consider isolating or limiting the use of affected JeecgBoot versions in sensitive environments until a fix is released.
