CVE-2025-13394 WSO2 CVE debrief

Who should care

Administrators and users of the Carbon console, especially those with exposed services, should be aware of the potential risks and take necessary precautions to secure their environments.

Technical summary

The Ajax processor in the Carbon console is vulnerable to Cross-Site Request Forgery (CSRF) attacks. It uses HTTP GET for state-changing operations, which can be exploited by an attacker to trick authenticated users into executing unintended actions, potentially leading to data modification or account changes. The vulnerability exists because the SameSite=Lax cookie attribute can be bypassed, allowing cookies to be sent with cross-origin top-level navigation requests, including GET requests. To mitigate this vulnerability, it is recommended to implement additional security measures, such as token-based validation for state-changing operations, and to monitor for and restrict cross-origin requests to the Carbon console. Verifying and enforcing secure configuration and guidelines provided by WSO2 can also help prevent exploitation of this vulnerability.

Defensive priority

Authenticated users of the Carbon console may be at risk of unintended actions if the console and related services are exposed to the public internet, contrary to WSO2's security guidelines.

Recommended defensive actions

• Review and update the exposure of the Carbon console and related services to ensure they are not publicly accessible.
• Implement additional security measures to mitigate CSRF attacks, such as token-based validation for state-changing operations.
• Monitor for and restrict cross-origin requests to the Carbon console.
• Verify and enforce secure configuration and guidelines provided by WSO2.
• Educate users on the risks associated with unintended actions via cross-origin requests.

Evidence notes

The CVE record indicates that the Ajax processor in the Carbon console is vulnerable to Cross-Site Request Forgery (CSRF) attacks due to its use of HTTP GET for state-changing operations, which can be bypassed by the SameSite=Lax cookie attribute. Limited information is available on the vendor's security guidelines for exposure to the public internet.
