ecrire/exec/valider_xml.php in SPIP 3.1.2 and earlier allows remote attackers to conduct server side request forgery (SSRF) attacks via a URL in the var_url parameter in a valider_xml action.
Weakness
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.
