Wso2: >> Api Manager >> 4.0.0 Security Vulnerabilities
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.

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.

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.

An authenticated remote code execution (RCE) vulnerability exists in multiple WSO2 products due to improper input validation in the event processor admin service. A user with administrative access to the SOAP admin services can exploit this flaw by deploying a Siddhi execution plan containing malicious Java code, resulting in arbitrary code execution on the server.
Exploitation of this vulnerability requires a valid user account with administrative privileges, limiting the attack surface to authenticated but potentially malicious users.

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.

A reflected cross-site scripting (XSS) vulnerability exists in multiple WSO2 products due to insufficient output encoding in error messages generated by the JDBC user store connection validation request. A malicious actor can inject a specially crafted payload into the request, causing the browser to execute arbitrary JavaScript in the context of the vulnerable page.
This vulnerability may allow UI manipulation, redirection to malicious websites, or data exfiltration from the browser. However, since all session-related sensitive cookies are protected with the httpOnly flag, session hijacking is not possible.
