Api Manager

The component accepts XML input through the publisher without disabling external entity resolution. This allows malicious actors to submit a crafted XML payload that exploits the unescaped external entity references. By leveraging this vulnerability, a malicious actor can read confidential files from the product's file system or access limited HTTP resources reachable via HTTP GET requests to the vulnerable product.Show less

The WSO2 API Manager developer portal accepts user-supplied input without enforcing expected validation constraints or proper output encoding. This deficiency allows a malicious actor to inject script content that is executed within the context of a user's browser. By leveraging this cross-site scripting vulnerability, a malicious actor can cause the browser to redirect to a malicious website, make changes to the UI of the web page, or retrieve information from the browser. However, session hijacking is not possible as all session-related sensitive cookies are protected by the httpOnly flag.Show less

The authentication endpoint fails to adequately validate user-supplied input before reflecting it back in the response. This allows an attacker to inject malicious script payloads into the input parameters, which are then executed by the victim's browser. Successful exploitation can enable an attacker to redirect the user's browser to a malicious website, modify the UI of the web page, or retrieve information from the browser. However, the impact is limited as session-related sensitive cookies are protected by the httpOnly flag, preventing session hijacking.Show less

The XML parsers within multiple WSO2 products accept user-supplied XML data without properly configuring to prevent the resolution of external entities. This omission allows malicious actors to craft XML payloads that exploit the parser's behavior, leading to the inclusion of external resources. By leveraging this vulnerability, an attacker can read confidential files from the file system and access limited HTTP resources reachable by the product. Additionally, the vulnerability can be exploited to perform denial of service attacks by exhausting server resources through recursive entity expansion or fetching large external resources.Show less

When the "Silent Just-In-Time Provisioning" feature is enabled for a federated identity provider (IDP) there is a risk that a local user store user's information may be replaced during the account provisioning process in cases where federated users share the same username as local users. There will be no impact on your deployment if any of the preconditions mentioned below are not met. Only when all the preconditions mentioned below are fulfilled could a malicious actor associate a targeted local user account with a federated IDP user account that they control. The Deployment should have: -An IDP configured for federated authentication with Silent JIT provisioning enabled. The malicious actor should have: -A fresh valid user account in the federated IDP that has not been used earlier. -Knowledge of the username of a valid user in the local IDP. -An account at the federated IDP matching the targeted local username.Show less

A malicious actor with administrative privileges can upload an arbitrary file to a user-controlled location within the deployment via a system REST API. Successful uploads may lead to remote code execution. By leveraging the vulnerability, a malicious actor may perform Remote Code Execution by uploading a specially crafted payload.Show less

A missing authentication enforcement vulnerability exists in the mutual TLS (mTLS) implementation used by System REST APIs and SOAP services in multiple WSO2 products. Due to improper validation of client certificate–based authentication in certain default configurations, the affected components may permit unauthenticated requests even when mTLS is enabled. This condition occurs when relying on the default mTLS settings for System REST APIs or when the mTLS authenticator is enabled for SOAP services, causing these interfaces to accept requests without enforcing additional authentication. Successful exploitation allows a malicious actor with network access to the affected endpoints to gain administrative privileges and perform unauthorized operations. The vulnerability is exploitable only when the impacted mTLS flows are enabled and accessible in a given deployment. Other certificate-based authentication mechanisms such as Mutual TLS OAuth client authentication and X.509 login flows are not affected, and APIs served through the API Gateway of WSO2 API Manager remain unaffected.Show less

A Cross-Site Request Forgery (CSRF) vulnerability exists in multiple WSO2 products due to the use of the HTTP GET method for state-changing operations within admin services, specifically in the event processor of the Carbon console. Although the SameSite=Lax cookie attribute is used as a mitigation, it is ineffective in this context because it allows cookies to be sent with cross-origin top-level navigations using GET requests. A malicious actor can exploit this vulnerability by tricking an authenticated user into visiting a crafted link, leading the browser to issue unintended state-changing requests. Successful exploitation could result in unauthorized operations such as data modification, account changes, or other administrative actions. According to WSO2 Secure Production Guidelines, exposure of Carbon console services to untrusted networks is discouraged, which may reduce the impact in properly secured deployments.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

Due to an insufficient access control implementation in multiple WSO2 Products, authentication and authorization checks for certain REST APIs can be bypassed, allowing them to be invoked without proper validation. Successful exploitation of this vulnerability could lead to a malicious actor gaining administrative access and performing unauthenticated and unauthorized administrative operations.Show less

A content spoofing vulnerability exists in multiple WSO2 products due to improper error message handling. Under certain conditions, error messages are passed through URL parameters without validation, allowing malicious actors to inject arbitrary content into the UI. By exploiting this vulnerability, attackers can manipulate browser-displayed error messages, enabling social engineering attacks through deceptive or misleading content.Show less
