AI-suggested
To mitigate CVE-2025-11093, European organizations should immediately review and restrict access to the GraalJS and NashornJS Script Mediator engines. Limit scripting engine permissions strictly to trusted administrators and avoid granting API creators or other users elevated scripting privileges unless absolutely necessary. Implement robust identity and access management controls, including multi-factor authentication for privileged accounts, to reduce the risk of credential compromise. Monitor and audit all scripting activity within the integration runtime to detect anomalous behavior indicative of exploitation attempts. Network segmentation and isolation of integration runtimes can limit the blast radius if compromise occurs. Apply vendor patches promptly once released; in the absence of patches, consider disabling scripting features if feasible or deploying compensating controls such as runtime application self-protection (RASP) or endpoint detection and response (EDR) solutions to monitor for suspicious code execution. Conduct thorough security reviews of integration workflows and scripts to identify and remediate insecure configurations. Educate privileged users on the risks associated with scripting engines and enforce strict change management policies. Finally, maintain up-to-date backups and incident response plans tailored to integration platform compromises.
Description
CVE-2025-11093 is a high-severity arbitrary code execution vulnerability in WSO2 Micro Integrator and related WSO2 products. It arises from insufficient restrictions in the GraalJS and NashornJS Script Mediator engines, allowing authenticated users with elevated privileges to execute arbitrary code within the integration runtime. By default, scripting engine access is limited to administrators in WSO2 Micro Integrator and Enterprise Integrator, but also includes API creators in WSO2 API Manager, potentially broadening the attack surface. Exploitation requires privileged authentication but no user interaction, impacting confidentiality, integrity, and availability severely. No known exploits are reported in the wild yet. European organizations using affected WSO2 versions 4.0.0 through 4.4.0 should prioritize patching and restrict scripting engine access.
