Wso2: >> Identity Server >> 6.0.0.254 Security Vulnerabilities
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.

When an Event Publisher output adapter is configured with irrelevant properties, the affected products log these properties. This logging occurs without sufficient validation or sanitization of the property values.
A malicious actor with access to the 'wso2carbon' log files could retrieve sensitive information, such as user credentials or other confidential data, that was inadvertently logged due to misconfiguration, potentially leading to unauthorized access.

The Ajax processor within the Carbon console fails to adequately protect state-changing operations from Cross-Site Request Forgery (CSRF) attacks. Specifically, it utilizes the HTTP GET method for these operations, and while the SameSite=Lax cookie attribute is employed for mitigation, this mechanism is bypassed as it permits cookies to be sent with cross-origin top-level navigation requests, including GET requests. This allows an attacker to trick an authenticated user's browser into unknowingly executing unintended actions.
An attacker can exploit this vulnerability to perform unauthorized state-altering requests on behalf of authenticated users. This could lead to consequences such as data modification, account changes, or other actions that could result in data compromise or loss of user control over their account. However, this attack is only feasible if the Carbon console and related services are exposed to the public internet, which is not recommended according to WSO2's security guidelines.

The Secret Type Management REST API does not correctly isolate access controls when deleting a secret type. The on-delete cascade logic, when triggered, fails to enforce organizational boundaries, leading to the removal of secrets associated with that type across all organizations.
Exploitation of this vulnerability can result in the unintended deletion of secrets across the entire deployment, potentially causing configuration failures, service interruptions, and a denial-of-service condition. This vulnerability requires delete permissions for the Secret Type Management REST API, which are by default only granted to administrators.

The affected product accepts user-supplied input within a URL parameter without enforcing expected sanitization or encoding before rendering it within the response. This condition allows for the injection of malicious JavaScript payloads.
An attacker can leverage this vulnerability to cause the user's browser to redirect to a malicious website, modify the user interface of the webpage, or retrieve sensitive information from the browser. However, the impact is mitigated for session hijacking as all session-related sensitive cookies are protected by the httpOnly flag.

The software accepts user-supplied input via a URL parameter without adequate output encoding before reflecting it back to the user's browser. This condition allows an attacker to inject malicious script content into pages served by the application.
By leveraging this weakness, an attacker can cause the user's browser to redirect to a malicious website, modify the UI of the webpage, or retrieve information from the browser. However, the impact is mitigated by the use of httpOnly flags on session-related cookies, preventing session hijacking.
