CVE-2025-10713 identifies a security vulnerability classified under CWE-611, which pertains to improper restriction of XML External Entity (XXE) references in WSO2 Enterprise Integrator version 6.6.0. The root cause is the insufficient configuration of the XML parser that processes user-supplied XML data without adequately restricting the resolution of external entities. This misconfiguration allows an attacker, remotely and without authentication, to craft malicious XML payloads that force the parser to resolve external entities. Exploiting this flaw can enable attackers to read arbitrary files on the server hosting the WSO2 Enterprise Integrator, potentially exposing sensitive configuration files, credentials, or other confidential data. Additionally, the vulnerability can be leveraged to trigger denial-of-service (DoS) attacks by causing the XML parser to enter resource-intensive loops or access unavailable resources, thereby degrading or halting service availability. The CVSS 3.1 base score of 6.5 reflects a medium severity level, with an attack vector over the network, low attack complexity, but requiring high privileges (PR:H), and no user interaction needed. The impact on confidentiality is high due to possible data disclosure, while integrity is not affected, and availability impact is high due to potential DoS. No known public exploits have been reported yet, but the vulnerability is publicly disclosed and should be treated seriously. The vulnerability affects specifically version 6.6.0 of WSO2 Enterprise Integrator, a middleware product widely used for enterprise application integration, API management, and service orchestration.

For European organizations, the impact of CVE-2025-10713 can be significant, especially for those relying on WSO2 Enterprise Integrator 6.6.0 for critical business processes and data integration. Unauthorized disclosure of sensitive files could lead to exposure of intellectual property, customer data, or internal credentials, which can facilitate further attacks or regulatory non-compliance under GDPR. The potential for denial-of-service attacks threatens operational continuity, risking downtime of essential integration services that connect disparate enterprise systems. This can disrupt supply chains, financial transactions, or customer-facing applications. Given the medium severity and the requirement for high privileges, the threat is more pronounced in environments where internal or semi-trusted users or compromised accounts exist. The absence of known exploits in the wild provides a window for proactive mitigation, but the public disclosure increases the risk of future exploitation attempts. Organizations in sectors such as finance, manufacturing, telecommunications, and government, which heavily depend on integration platforms, are particularly vulnerable to operational and reputational damage.

To mitigate CVE-2025-10713, organizations should immediately review and harden XML parser configurations within WSO2 Enterprise Integrator 6.6.0. Specifically, disable XML External Entity (XXE) processing by setting parser features such as 'http://apache.org/xml/features/disallow-doctype-decl' to true and disabling external entity resolution features. If possible, upgrade to a patched version once WSO2 releases a fix. In the interim, implement strict input validation and sanitize all XML inputs to reject or neutralize malicious payloads. Employ network-level controls such as web application firewalls (WAFs) with custom rules to detect and block suspicious XML entity references. Monitor logs for unusual XML parsing errors or access patterns indicative of exploitation attempts. Limit privileges of service accounts running the integrator to minimize impact if exploited. Conduct regular security assessments and penetration tests focusing on XML processing components. Finally, maintain an incident response plan tailored to integration platform compromises to ensure rapid containment and recovery.
