Technical Description
Cross-origin resource sharing (CORS) enables browsers to perform cross domain requests in a controlled manner. This request has an Origin header that identifies the domain that is making the initial request and defines the protocol between a browser and server to see if the request is allowed. An attacker can take advantage of this and possibly carry out privileged actions and access sensitive information when the Access-Control-Allow-Credentials is enabled.
Remediation
Check the references section for vendor advisories and patches from hcltech. Update onetest_server to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
