SSRF in Sourcentis Mercator
CVE-2026-49345
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.
