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

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.Show less

An authenticated stored cross-site scripting (XSS) vulnerability exists in multiple WSO2 products due to improper validation of user-supplied input during API document upload in the Publisher portal. A user with publisher privileges can upload a crafted API document containing malicious JavaScript, which is later rendered in the browser when accessed by other users. A successful attack could result in redirection to malicious websites, unauthorized UI modifications, or exfiltration of browser-accessible data. However, session-related sensitive cookies are protected by the httpOnly flag, preventing session hijacking.Show less

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.Show less

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.Show less

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.Show less

A stored cross-site scripting (XSS) vulnerability exists in the Management Console of multiple WSO2 products due to insufficient input validation in the Rich Text Editor within the registry section. To exploit this vulnerability, a malicious actor must have a valid user account with administrative access to the Management Console. If successful, the actor could inject persistent JavaScript payloads, enabling the theft of user data or execution of unauthorized actions on behalf of other users. While this issue enables persistent client-side script execution, session-related cookies remain protected with the httpOnly flag, preventing session hijacking.Show less

An open redirection vulnerability exists in multiple WSO2 products due to improper validation of the multi-option URL in the authentication endpoint when multi-option authentication is enabled. A malicious actor can craft a valid link that redirects users to an attacker-controlled site. By exploiting this vulnerability, an attacker may trick users into visiting a malicious page, enabling phishing attacks to harvest sensitive information or perform other harmful actions.Show less

An incorrect authorization vulnerability exists in multiple WSO2 products due to a flaw in the SOAP admin service, which allows user account creation regardless of the self-registration configuration settings. This vulnerability enables malicious actors to create new user accounts without proper authorization. Exploitation of this flaw could allow an attacker to create multiple low-privileged user accounts, gaining unauthorized access to the system. Additionally, continuous exploitation could lead to system resource exhaustion through mass user creation.Show less

A privilege escalation vulnerability exists in multiple WSO2 products due to a business logic flaw in SOAP admin services. A malicious actor can create a new user with elevated permissions only when all of the following conditions are met: * SOAP admin services are accessible to the attacker. * The deployment includes an internally used attribute that is not part of the default WSO2 product configuration. * At least one custom role exists with non-default permissions. * The attacker has knowledge of the custom role and the internal attribute used in the deployment. Exploiting this vulnerability allows malicious actors to assign higher privileges to self-registered users, bypassing intended access control mechanisms.Show less

A reflected cross-site scripting (XSS) vulnerability exists in the authentication endpoint of multiple WSO2 products due to missing output encoding of user-supplied input. A malicious actor can exploit this vulnerability to inject arbitrary JavaScript into the authentication flow, potentially leading to UI modifications, redirections to malicious websites, or data exfiltration from the browser. While this issue could allow an attacker to manipulate the user’s browser, session-related sensitive cookies remain protected with the httpOnly flag, preventing session hijacking.Show less

An incorrect authorization vulnerability exists in multiple WSO2 products due to a business logic flaw in the account recovery-related SOAP admin service. A malicious actor can exploit this vulnerability to reset the password of any user account, leading to a complete account takeover, including accounts with elevated privileges. This vulnerability is exploitable only through the account recovery SOAP admin services exposed via the "/services" context path in affected products. The impact may be reduced if access to these endpoints has been restricted based on the "Security Guidelines for Production Deployment" by disabling exposure to untrusted networks.Show less

Due to the improper configuration of XML parser, user-supplied XML is parsed without applying sufficient restrictions, enabling XML External Entity (XXE) resolution in multiple WSO2 Products. A successful XXE attack could allow a remote, unauthenticated attacker to: * Read sensitive files from the server’s filesystem. * Perform denial-of-service (DoS) attacks, which can render the affected service unavailable.Show less
