Wso2: >> Identity Server >> 5.11.0 Security Vulnerabilities
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.

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.

An arbitrary file upload vulnerability exists in multiple WSO2 products due to improper validation of user-supplied filenames in the BPEL uploader SOAP service endpoint. A malicious actor with administrative privileges can upload arbitrary files to a user-controlled location on the server.
By leveraging this vulnerability, an attacker can upload a specially crafted payload and achieve remote code execution (RCE), potentially compromising the server and its data.

A username enumeration vulnerability exists in multiple WSO2 products when Multi-Attribute Login is enabled. In this configuration, the system returns a distinct "User does not exist" error message to the login form, regardless of the validate_username setting. This behavior allows malicious actors to determine which usernames exist in the system based on observable discrepancies in the application's responses.
Exploitation of this vulnerability could aid in brute-force attacks, targeted phishing campaigns, or other social engineering techniques by confirming the validity of user identifiers within the system.

An authentication bypass vulnerability exists in multiple WSO2 products when FIDO authentication is enabled. When a user account is deleted, the system does not automatically remove associated FIDO registration data. If a new user account is later created using the same username, the system may associate the new account with the previously registered FIDO device.
This flaw may allow a previously deleted user to authenticate using their FIDO credentials and impersonate the newly created user, resulting in unauthorized access. The vulnerability applies only to deployments that utilize FIDO-based authentication.

A cross-tenant authentication vulnerability exists in multiple WSO2 products due to improper cryptographic design in Adaptive Authentication. A single cryptographic key is used across all tenants to sign authentication cookies, allowing a privileged user in one tenant to forge authentication cookies for users in other tenants.
Because the Auto-Login feature is enabled by default, this flaw may allow an attacker to gain unauthorized access and potentially take over accounts in other tenants. Successful exploitation requires access to Adaptive Authentication functionality, which is typically restricted to high-privileged users. The vulnerability is only exploitable when Auto-Login is enabled, reducing its practical impact in deployments where the feature is disabled.

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 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 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.
