The Conditional Authentication (Adaptive Authentication) script does not correctly enforce the completion of all required authentication steps when a specific multi-step pattern involving certain authenticators is configured. This allows an attacker to bypass intermediate authentication challenges by exploiting how the script handles callbacks and re-execution of authentication steps.

Successful exploitation allows a malicious actor to gain unauthorized access to a targeted user account. This vulnerability can only be exploited when all of the following conditions are met: the application login flow contains a specific secondary authenticator, the Conditional Authentication script is configured with particular event callbacks and re-executes an authentication step, the targeted user has one of the impacted authenticators enrolled, and the attacker successfully completes any preceding authentication steps.

The silent Just-In-Time (JIT) provisioning feature in federated authentication implementations fails to properly segregate user roles during account creation when a federated user shares a username with a local user. This allows the provisioning process to overwrite existing roles of local users with roles assigned to the federated user.

Exploitation requires a federated identity provider (IDP) with silent JIT provisioning enabled and an attacker's knowledge of a local user's username. When these conditions are met, a malicious individual can leverage the JIT provisioning process to modify the roles of local users. The overwritten roles are limited to those defined within the federated IDP, typically granting minimal access rights unless explicitly configured otherwise by the federated IDP administrator.

A missing authentication enforcement vulnerability exists in the mutual TLS (mTLS) implementation used by System REST APIs and SOAP services in multiple WSO2 products. Due to improper validation of client certificate–based authentication in certain default configurations, the affected components may permit unauthenticated requests even when mTLS is enabled. This condition occurs when relying on the default mTLS settings for System REST APIs or when the mTLS authenticator is enabled for SOAP services, causing these interfaces to accept requests without enforcing additional authentication.

Successful exploitation allows a malicious actor with network access to the affected endpoints to gain administrative privileges and perform unauthorized operations. The vulnerability is exploitable only when the impacted mTLS flows are enabled and accessible in a given deployment. Other certificate-based authentication mechanisms such as Mutual TLS OAuth client authentication and X.509 login flows are not affected, and APIs served through the API Gateway of WSO2 API Manager remain unaffected.

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.

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.

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.

The Management Console in certain WSO2 products allows XXE attacks during EventReceiver updates. This affects API Manager through 3.0.0, API Manager Analytics 2.2.0 and 2.5.0, API Microgateway 2.2.0, Enterprise Integrator 6.2.0 and 6.3.0, and Identity Server Analytics through 5.6.0.

In WSO2 API Manager 3.0.0 and earlier, WSO2 API Microgateway 2.2.0, and WSO2 IS as Key Manager 5.9.0 and earlier, Management Console allows XXE during addition or update of a Lifecycle.

WSO2 API Manager 3.0.0 does not properly restrict outbound network access from a Publisher node, opening up the possibility of SSRF to this node's entire intranet.

XXE during an EventPublisher update can occur in Management Console in WSO2 API Manager 3.0.0 and earlier, API Manager Analytics 2.5.0 and earlier, API Microgateway 2.2.0, Enterprise Integrator 6.4.0 and earlier, IS as Key Manager 5.9.0 and earlier, Identity Server 5.9.0 and earlier, and Identity Server Analytics 5.6.0 and earlier.

XML External Entity (XXE) vulnerability in the file based service provider creation feature of the Management Console in WSO2 API Manager 2.6.0, 3.0.0, 3.1.0, 3.2.0, and 4.0.0; and WSO2 IS as Key Manager 5.7.0, 5.9.0, and 5.10.0; and WSO2 Identity Server 5.7.0, 5.8.0, 5.9.0, 5.10.0, and 5.11.0. Allows attackers to gain read access to sensitive information or cause a denial of service via crafted GET requests.

In accountrecoveryendpoint/recoverpassword.do in WSO2 Identity Server 5.7.0, it is possible to perform a DOM-Based XSS attack affecting the callback parameter modifying the URL that precedes the callback parameter. Once the username or password reset procedure is completed, the JavaScript code will be executed. (recoverpassword.do also has an open redirect issue for a similar reason.)

A reflected XSS issue exists in the Management Console of several WSO2 products. This affects API Manager 2.2.0, 2.5.0, 2.6.0, 3.0.0, 3.1.0, 3.2.0, and 4.0.0; API Manager Analytics 2.2.0, 2.5.0, and 2.6.0; API Microgateway 2.2.0; Data Analytics Server 3.2.0; Enterprise Integrator 6.2.0, 6.3.0, 6.4.0, 6.5.0, and 6.6.0; IS as Key Manager 5.5.0, 5.6.0, 5.7.0, 5.9.0, and 5.10.0; Identity Server 5.5.0, 5.6.0, 5.7.0, 5.9.0, 5.10.0, and 5.11.0; Identity Server Analytics 5.5.0 and 5.6.0; and WSO2 Micro Integrator 1.0.0.

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 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.
