The Ajax processor within the Carbon console fails to adequately protect state-changing operations from Cross-Site Request Forgery (CSRF) attacks. Specifically, it utilizes the HTTP GET method for these operations, and while the SameSite=Lax cookie attribute is employed for mitigation, this mechanism is bypassed as it permits cookies to be sent with cross-origin top-level navigation requests, including GET requests. This allows an attacker to trick an authenticated user's browser into unknowingly executing unintended actions.

An attacker can exploit this vulnerability to perform unauthorized state-altering requests on behalf of authenticated users. This could lead to consequences such as data modification, account changes, or other actions that could result in data compromise or loss of user control over their account. However, this attack is only feasible if the Carbon console and related services are exposed to the public internet, which is not recommended according to WSO2's security guidelines.

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 and above through 4.0.0; WSO2 Identity Server 5.2.0 and above through 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 and above through 5.10.0; and WSO2 Enterprise Integrator 6.2.0 and above through 6.6.0.

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 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 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.

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.

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 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.

A Cross-Site Request Forgery (CSRF) vulnerability exists in the management console of WSO2 Enterprise Integrator 6.6.0 due to the absence of CSRF token validation. This flaw allows attackers to craft malicious requests that can trigger state-changing operations on behalf of an authenticated user, potentially compromising account settings and data integrity. The vulnerability only affects a limited set of state-changing operations, and successful exploitation requires social engineering to trick a user with access to the management console into performing the malicious action.
