The Management Console in certain WSO2 products allows XXE attacks during EventReceiver updates. This affects API Manager through 3.0.0, API Manager Analytics 2.2.0 and 2.5.0, API Microgateway 2.2.0, Enterprise Integrator 6.2.0 and 6.3.0, and Identity Server Analytics through 5.6.0.
XXE during an EventPublisher update can occur in Management Console in WSO2 API Manager 3.0.0 and earlier, API Manager Analytics 2.5.0 and earlier, API Microgateway 2.2.0, Enterprise Integrator 6.4.0 and earlier, IS as Key Manager 5.9.0 and earlier, Identity Server 5.9.0 and earlier, and Identity Server Analytics 5.6.0 and earlier.
WSO2 Enterprise Integrator through 6.6.0 has an XXE vulnerability where a user (with admin console access) can use the XML validator to make unintended network invocations such as SSRF via an uploaded file.
