Wso2: >> Api Manager >> 4.2.0 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.

A reflected cross-site scripting (XSS) vulnerability exists in the authentication endpoints of multiple WSO2 products due to a lack of output encoding. A malicious actor can inject arbitrary JavaScript payloads into the authentication endpoint, which are reflected back in the response, enabling browser-based attacks.
Exploitation may result in redirection to malicious websites, UI manipulation, or unauthorized data access from the victim’s browser. However, session-related cookies are protected with the httpOnly flag, which mitigates session hijacking via this vector.

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 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.

An improper privilege management vulnerability exists in WSO2 API Manager due to missing authentication and authorization checks in the keymanager-operations Dynamic Client Registration (DCR) endpoint.
A malicious user can exploit this flaw to generate access tokens with elevated privileges, potentially leading to administrative access and the ability to perform unauthorized operations.
