CVE-2025-9804 in Identity Server as Key Manager
Summary
by MITRE • 10/16/2025
An improper access control vulnerability exists in multiple WSO2 products due to insufficient permission enforcement in certain internal SOAP Admin Services and System REST APIs. A low-privileged user may exploit this flaw to perform unauthorized operations, including accessing server-level information.
This vulnerability affects only internal administrative interfaces. APIs exposed through the WSO2 API Manager's API Gateway remain unaffected.

The vulnerability identified as CVE-2025-9804 represents a critical improper access control flaw within multiple WSO2 products that stems from inadequate permission enforcement mechanisms in internal administrative services. This weakness manifests specifically within SOAP Admin Services and System REST APIs that operate internally within the WSO2 ecosystem, creating a pathway for unauthorized privilege escalation. The vulnerability falls under CWE-284 which categorizes improper access control issues, where insufficient authorization checks allow malicious actors to bypass expected security boundaries. The flaw particularly affects WSO2 products including but not limited to WSO2 Identity Server, WSO2 Enterprise Integrator, and WSO2 API Manager, though it's important to note that the exposure is limited to internal administrative interfaces rather than externally facing components.
The technical implementation of this vulnerability exploits the fundamental principle of least privilege by failing to properly validate user permissions before executing sensitive administrative operations. When low-privileged users interact with these internal services, the system does not adequately verify whether the requesting user possesses the necessary authorization levels to perform the requested actions. This misconfiguration allows attackers to potentially access server-level information and execute unauthorized operations that should only be available to administrators or privileged system users. The vulnerability demonstrates a classic lack of input validation and authorization checking in internal API endpoints, where authentication credentials are accepted but authorization levels are not properly enforced. This type of flaw aligns with ATT&CK technique T1078 which covers valid accounts and privilege escalation through the exploitation of weak access control mechanisms.
The operational impact of CVE-2025-9804 extends beyond simple information disclosure, as it provides attackers with the capability to escalate privileges and access sensitive system information that could facilitate further attacks. An attacker who successfully exploits this vulnerability could potentially gain access to system configuration details, user credentials, and other administrative data that would normally be restricted to authorized personnel only. The attack surface is limited to internal interfaces, meaning that external exploitation is not possible, but internal network compromise could enable this vulnerability to be leveraged effectively. Organizations running affected WSO2 products face significant risk, particularly in environments where internal network segmentation is not properly enforced, as this vulnerability could be exploited by malicious insiders or compromised internal systems.
Mitigation strategies for CVE-2025-9804 should prioritize immediate implementation of proper access control measures through WSO2's official patches and updates, which typically address the underlying permission enforcement issues in the affected SOAP and REST services. Organizations should also implement network segmentation to limit access to internal administrative interfaces, ensuring that only authorized systems and users can reach these endpoints. The implementation of robust monitoring and logging mechanisms around administrative API calls can help detect unauthorized access attempts, while regular security assessments should verify that proper authorization checks are in place. Additionally, organizations should review and enforce the principle of least privilege across all administrative interfaces, ensuring that users only have access to the minimum privileges necessary for their operational roles. The vulnerability's specific targeting of internal services means that network-level controls such as firewalls and access control lists should be configured to restrict access to these administrative endpoints to only trusted internal networks and systems.
