Detailsinfo

A vulnerability was found in sourcentis mercator up to 2025.05.18. It has been rated as critical. This issue affects the function testProvider of the file /admin/config/parameters. The manipulation with an unknown input leads to a server-side request forgery vulnerability. Using CWE to declare the problem leads to CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Mercator is an open source web application that enables mapping of the information system. Prior to version 2025.05.19, a Server-Side Request Forgery (SSRF) vulnerability exists in Mercator's CVE configuration panel (`/admin/config/parameters`). The `testProvider()` method in `ConfigurationController` passes user-supplied input directly to `curl_init()` without validating the scheme, hostname, or destination IP address. An authenticated user with the `configure` permission can force the Mercator server to issue arbitrary outbound network requests. The suffix `/api/dbInfo` appended to the URL can be bypassed by injecting a `#` fragment character (e.g. `http://TARGET/PATH#`), allowing full control over the target URL. No scheme whitelist, host whitelist, or private/loopback IP block is applied. The `telnet://` scheme can be used for internal port scanning; the `gopher://` scheme enables interaction with unauthenticated internal services (Redis, Memcached), potentially leading to Remote Code Execution under specific deployment conditions. Version 2025.05.19 patches the issue.
