CVE-2025-10247 is a security vulnerability identified in version 7.2.8 of JEPaaS, specifically affecting the doFilterInternal function within the Filter Handler component. This vulnerability arises from improper access controls, which means that the filtering mechanism intended to restrict or validate access to certain resources or functionalities is flawed. An attacker can exploit this weakness remotely without requiring user interaction or prior authentication, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:L). The vulnerability allows an attacker with limited privileges (PR:L) to bypass intended access restrictions, potentially gaining unauthorized access to sensitive data or functionality within the JEPaaS platform. The CVSS 4.0 base score of 5.3 classifies this as a medium severity issue, reflecting moderate impact on confidentiality, integrity, and availability, with relatively low complexity for exploitation. The vendor has been contacted but has not responded, and no patches or mitigations have been published yet. Although no known exploits are reported in the wild, the public disclosure of the vulnerability increases the risk of exploitation attempts. JEPaaS is a platform-as-a-service solution, and improper access control vulnerabilities in such environments can lead to unauthorized data exposure, privilege escalation, or disruption of services, depending on the deployment context and the sensitivity of hosted applications or data.

For European organizations using JEPaaS 7.2.8, this vulnerability poses a tangible risk of unauthorized access to internal resources or data. Since the exploit can be executed remotely without user interaction, attackers could leverage this flaw to bypass security controls, potentially leading to data breaches, unauthorized modifications, or service disruptions. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, could face regulatory repercussions under GDPR if sensitive personal data is exposed. The medium severity rating suggests that while the vulnerability is not critical, it still represents a significant security concern that could be leveraged as part of a broader attack chain. The lack of vendor response and absence of patches increases the urgency for organizations to implement compensating controls. Additionally, the presence of limited privilege requirements lowers the barrier for exploitation, making it more accessible to a wider range of threat actors. The impact could extend to operational disruptions if attackers manipulate access controls to interfere with service availability or integrity.

Given the absence of official patches, European organizations should implement specific mitigations to reduce risk. First, conduct a thorough audit of all JEPaaS 7.2.8 deployments to identify affected instances. Restrict network exposure of JEPaaS management and API endpoints by implementing strict firewall rules and network segmentation, limiting access to trusted IP addresses only. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the doFilterInternal function or unusual access patterns. Enhance monitoring and logging around access control events within JEPaaS to detect potential exploitation attempts early. Where possible, upgrade to a later, unaffected version of JEPaaS once available or consider temporary migration to alternative platforms. Implement strict role-based access controls (RBAC) and least privilege principles within JEPaaS to minimize the impact of any unauthorized access. Engage in proactive threat hunting and incident response readiness to quickly identify and respond to exploitation attempts. Finally, maintain communication with the vendor and security communities for updates or patches.
