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.

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 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.

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.
