Wso2: >> Api Manager >> 3.2.1.27 Security Vulnerabilities
The software fails to enforce role-based access controls for certain Gateway API invocations. Users with the 'Internal/Everyone' role can invoke these APIs, bypassing intended permission checks. This same vulnerability also affects Internal Service APIs, potentially exposing them in WSO2 APIM 3.x versions.
A malicious actor with a valid user account on a vulnerable deployment can perform sensitive operations against the Gateway REST API regardless of their actual roles or privileges. This could lead to unintended behavior or misuse, particularly in production environments.

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.

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 information disclosure vulnerability exists in multiple WSO2 products due to improper implementation of the enrich mediator. Authenticated users may be able to view unintended business data from other mediation contexts because the internal state is not properly isolated or cleared between executions.
This vulnerability does not impact user credentials or access tokens but may lead to leakage of sensitive business information handled during message flows.

CVE-2022-29464
Certain WSO2 products allow unrestricted file upload with resultant remote code execution. The attacker must use a /fileupload endpoint with a Content-Disposition directory traversal sequence to reach a directory under the web root, such as a ../../../../repository/deployment/server/webapps directory. This affects WSO2 API Manager 2.2.0 up to 4.0.0, WSO2 Identity Server 5.2.0 up to 5.11.0, WSO2 Identity Server Analytics 5.4.0, 5.4.1, 5.5.0 and 5.6.0, WSO2 Identity Server as Key Manager 5.3.0 up to 5.11.0, WSO2 Enterprise Integrator 6.2.0 up to 6.6.0, WSO2 Open Banking AM 1.4.0 up to 2.0.0 and WSO2 Open Banking KM 1.4.0, up to 2.0.0.
