Wso2: >> Enterprise Integrator >> 6.6.0 Security Vulnerabilities
A reflected cross-site scripting (XSS) vulnerability exists in the management console of multiple WSO2 products due to improper output encoding. By tampering with specific parameters, a malicious actor can inject arbitrary JavaScript into the response, leading to reflected XSS.
Successful exploitation could result in UI manipulation, redirection to malicious websites, or data theft from the browser. However, session-related sensitive cookies are protected with the httpOnly flag, which mitigates the risk of session hijacking.

An arbitrary code execution vulnerability exists in multiple WSO2 products due to insufficient restrictions in the GraalJS and NashornJS Script Mediator engines. Authenticated users with elevated privileges can execute arbitrary code within the integration runtime environment.
By default, access to these scripting engines is limited to administrators in WSO2 Micro Integrator and WSO2 Enterprise Integrator, while in WSO2 API Manager, access extends to both administrators and API creators. This may allow trusted-but-privileged users to perform unauthorized actions or compromise the execution environment.

An arbitrary file upload vulnerability exists in multiple WSO2 products due to insufficient validation of uploaded content and destination in SOAP admin services. A malicious actor with administrative privileges can upload a specially crafted file to a user-controlled location within the deployment.
Successful exploitation may lead to remote code execution (RCE) on the server, depending on how the uploaded file is processed. By default, this vulnerability is only exploitable by users with administrative access to the affected SOAP services.

An XML External Entity (XXE) vulnerability exists in multiple WSO2 products due to improper configuration of the XML parser. The application parses user-supplied XML without applying sufficient restrictions, allowing resolution of external entities.
A successful attack could enable a remote, unauthenticated attacker to read sensitive files from the server's filesystem or perform denial-of-service (DoS) attacks that render affected services unavailable.

An arbitrary file upload vulnerability exists in multiple WSO2 products due to improper input validation in the CarbonAppUploader admin service endpoint. An authenticated attacker with appropriate privileges can upload a malicious file to a user-controlled location on the server, potentially leading to remote code execution (RCE).
This functionality is restricted by default to admin users; therefore, successful exploitation requires valid credentials with administrative permissions.

An authentication bypass vulnerability exists in the Management Console of multiple WSO2 products. A malicious actor with access to the console can manipulate the request URI to bypass authentication and access certain restricted resources, resulting in partial information disclosure.
The known exposure from this issue is limited to memory statistics. While the vulnerability does not allow full account compromise, it still enables unauthorized access to internal system details.

SSRF and Reflected XSS Vulnerabilities exist in multiple WSO2 products within the deprecated Try-It feature, which was accessible only to administrative users. This feature accepted user-supplied URLs without proper validation, leading to server-side request forgery (SSRF). Additionally, the retrieved content was directly reflected in the HTTP response, enabling reflected cross-site scripting (XSS) in the admin user's browser context.
By tricking an administrator into accessing a crafted link, an attacker could force the server to fetch malicious content and reflect it into the admin’s browser, leading to arbitrary JavaScript execution for UI manipulation or data exfiltration. While session cookies are protected with the HttpOnly flag, the XSS still poses a significant security risk.
Furthermore, SSRF can be used by a privileged user to query internal services, potentially aiding in internal network enumeration if the target endpoints are reachable from the affected product.

An improper access control vulnerability exists in WSO2 Enterprise Integrator product due to insufficient permission restrictions on internal SOAP admin services related to system logs and user-store configuration. A low-privileged user can access log data and user-store configuration details that are not intended to be exposed at that privilege level.
While no credentials or sensitive user information are exposed, this vulnerability may allow unauthorized visibility into internal operational details, which could aid in further exploitation or reconnaissance.

An arbitrary file upload vulnerability exists in multiple WSO2 products due to improper validation of user-supplied filenames in the BPEL uploader SOAP service endpoint. A malicious actor with administrative privileges can upload arbitrary files to a user-controlled location on the server.
By leveraging this vulnerability, an attacker can upload a specially crafted payload and achieve remote code execution (RCE), potentially compromising the server and its data.

An incorrect authorization vulnerability exists in multiple WSO2 products that allows unauthorized access to versioned files stored in the registry. Due to flawed authorization logic, a malicious actor with access to the management console can exploit a specific bypass method to retrieve versioned files without proper authorization.
Successful exploitation of this vulnerability could lead to unauthorized disclosure of configuration or resource files that may be stored as registry versions, potentially aiding further attacks or system reconnaissance.
