Oracle WebCenter Sites Satellite Server – HTTP Header Injection
SEC Consult Vulnerability Lab Security Advisory < 20130417-2 > ======================================================================= title: HTTP header injection/Cache poisoning in Oracle WebCenter Sites Satellite Server product: Oracle WebCenter Sites Satellite Server (former FatWire Satellite Server) vulnerable version: 7.6.0 Patch1, 7.6.2, 11.1.1.6.0, 11.1.1.6.1 fixed version: Patch information see sections below CVE: CVE-2013-1509 impact: medium homepage: http://www.oracle.com/us/corporate/acquisitions/fatwire/index.html found: 2012-09-17 by: K. Gudinavicius SEC Consult Vulnerability Lab https://www.sec-consult.com ======================================================================= Vendor description: ------------------- FatWire Satellite Server is a predecessor product of Oracle WebCenter Sites Satellite Server. "Oracle WebCenter Sites Satellite Server enables organizations to deliver segmented, targeted, and dynamically assembled content across global Web properties with rapid response times and intelligent edge caching to optimize and speed the delivery of dynamic Web experiences." Source: http://www.oracle.com/us/products/middleware/webcenter/satellite-server/overview/index.html Vulnerability overview/description: ----------------------------------- Due to unsanitized user input it is possible to inject arbitrary HTTP header values in certain HTTP responses of the Satellite Server. This can be exploited, for example, to perform session fixation and malicious redirection attacks via the Set-Cookie and the Refresh headers. Moreover, the Satellite Server caches these HTTP responses with the injected HTTP header resulting in all further requests to the same resource being served with the poisoned HTTP response, while these objects remain in cache. Proof of concept: ----------------- An arbitrary header can be injected in the HTTP responses of the downloadable resources. The values of the blobheadername2 and the blobheadervalue2 URL parameters are user controllable. In the following example the Refresh header is injected: http://fatwire/cs/Satellite?blobcol=urldata&blobheadername1=content-type&blobheadername2=Refresh& blobheadervalue1=application/pdf&blobheadervalue2=0;url=http://www.sec-consult.com&blobkey=id& blobnocache=false&blobtable=MungoBlobs&blobwhere=1342534304149&ssbinary=true&site=S08 The returned HTTP response will contain the injected Refresh header and its value. Furthermore, the HTTP response will be cached, so the next time users will be accessing the same downloadable resource using the standard URL, they will be affected and redirected using the injected Refresh header value.
