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.

The Management Console in WSO2 API Manager through 3.1.0 and API Microgateway 2.2.0 allows XML Entity Expansion attacks.

Multiple WSO2 products have been identified as vulnerable due to improper output encoding, a Stored Cross Site Scripting (XSS) attack can be carried out by an attacker injecting a malicious payload into the Registry feature of the Management Console.

Due to improper error handling, a REST API resource could expose a server side error containing an internal WSO2 specific package name in the HTTP response.

Reflected XSS vulnerability can be exploited by tampering a request parameter in Authentication Endpoint. This can be performed in both authenticated and unauthenticated requests.

Multiple WSO2 products have been identified as vulnerable to perform user impersonatoin using JIT provisioning. In order for this vulnerability to have any impact on your deployment, following conditions must be met: * An IDP configured for federated authentication and JIT provisioning enabled with the "Prompt for username, password and consent" option. * A service provider that uses the above IDP for federated authentication and has the "Assert identity using mapped local subject identifier" flag enabled. Attacker 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. When all preconditions are met, a malicious actor could use JIT provisioning flow to perform user impersonation.

Multiple WSO2 products have been identified as vulnerable due to an XML External Entity (XXE) attack abuses a widely available but rarely used feature of XML parsers to access sensitive information.

Multiple WSO2 products have been identified as vulnerable due to lack of server-side input validation in the Forum feature, API rating could be manipulated.

A reflected cross-site scripting (XSS) vulnerability in /authenticationendpoint/login.do of WSO2 API Manager before 4.2.0 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the tenantDomain parameter.

A vulnerability classified as problematic has been found in WSO2 carbon-registry up to 4.8.6. This affects an unknown part of the component Request Parameter Handler. The manipulation of the argument parentPath/path/username/path/profile_menu leads to cross site scripting. It is possible to initiate the attack remotely. Upgrading to version 4.8.7 is able to address this issue. The name of the patch is 9f967abfde9317bee2cda469dbc09b57d539f2cc. It is recommended to upgrade the affected component. The identifier VDB-215901 was assigned to this vulnerability.
