CVE-2025-25036 is a vulnerability classified under CWE-611, which pertains to Improper Restriction of XML External Entity (XXE) Reference in the Jalios JPlatform product. This vulnerability arises because the platform improperly restricts XML external entity references, allowing an attacker to inject malicious XML content. Specifically, all versions of JPlatform 10 before 10.0.8 (SP8) are affected. The flaw enables an attacker with high privileges (authenticated user with elevated rights) to craft XML payloads that can cause the application to process external entities. This can lead to disclosure of sensitive information from the system where the platform is hosted, as the XML parser may access local files or network resources referenced by the external entities. The vulnerability does not directly affect the integrity or availability of the system but compromises confidentiality. The CVSS v3.1 base score is 6.8, with vector AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N, indicating network attack vector, low attack complexity, high privileges required, no user interaction, scope changed, high confidentiality impact, and no integrity or availability impact. No public exploits or active exploitation have been reported yet. The vulnerability was reserved on 2025-01-31 and published on 2025-03-21. Jalios JPlatform is a collaborative platform used by enterprises and public sector organizations, often in Europe, for intranet and content management solutions. The improper handling of XML external entities can be exploited by attackers who have already obtained high-level access to the platform, potentially escalating data exposure risks.

For European organizations, this vulnerability poses a significant confidentiality risk, especially for those using Jalios JPlatform in sensitive environments such as government, education, and large enterprises. The ability to perform XML external entity injection can lead to unauthorized disclosure of internal files or network resources, potentially exposing sensitive corporate or personal data protected under GDPR. Although exploitation requires high privileges, insider threats or compromised administrative accounts could leverage this vulnerability to extract confidential information. The scope change in the CVSS vector indicates that the vulnerability could affect components beyond the immediate application context, increasing the risk of broader data exposure. Since Jalios JPlatform is widely used in France and other European countries for intranet and collaboration services, the impact could be substantial in these regions. The lack of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time.

European organizations should immediately plan to upgrade Jalios JPlatform to version 10.0.8 (SP8) or later, where this vulnerability is fixed. Until patching is possible, restrict access to the platform to trusted administrators only and monitor for unusual XML processing activities or unexpected outbound network requests from the platform servers. Implement strict network segmentation and firewall rules to limit the platform's ability to access internal file systems or sensitive network resources. Conduct thorough audits of user privileges to ensure only necessary users have high-level access, reducing the risk of exploitation. Additionally, enable XML parser configurations that disable external entity processing if configurable within the platform or underlying XML libraries. Employ logging and alerting mechanisms to detect potential exploitation attempts involving XML payloads. Finally, review and update incident response plans to include scenarios involving XML external entity attacks.
