Wso2: >> Identity Server >> 5.6.0 Security Vulnerabilities
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.

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 server-side request forgery (SSRF) vulnerability exists in multiple WSO2 products due to improper input validation in SOAP admin services. This flaw allows unauthenticated attackers to manipulate server-side requests, enabling access to internal and external resources available through the network or filesystem.
Exploitation of this vulnerability could lead to unauthorized access to sensitive data and systems, including resources within private networks, as long as they are reachable by the affected product.

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.

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.

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.

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.
