CoreLabs regularly publishes security advisories, technical papers, project information and shared software tools for public use at. Our results include problem formalization, identification of vulnerabilities, novel solutions and prototypes for new technologies.

#Windows media center file location code

We conduct our research in several important areas of computer security including system vulnerabilities, cyber attack planning and simulation, source code auditing, and cryptography.

: Microsoft informed Core Security that they updated the CVE acknowledgment accordingly.Д¬oreLabs, the research center of Core Security, is charged with anticipating the future needs and requirements for information security technologies.: Core Security informed Microsoft of the link and name that should appear in the acknowledgment.

: Microsoft requested from Core Security the link where the advisory would be published and the name of the researcher that should appear in the acknowledgment.: Core Security thanked Microsoft for their reply and clarified that we would be publishing the advisory on Tuesday, the 8 of December, 2015.

They also informed us that they assigned CVE-2015-6127 to this case.

: Microsoft informed Core Security that they were targeting the security fix for this issue in their December release.

: Core Security asked Microsoft if they had determined a release date for the fix and a CVE ID to the reported vulnerability.

: Microsoft informed Core Security that they would be pursuing a fix for the reported issue and are working on a release date for it.

: Core Security asked Microsoft if there were any updates regarding the reported bug and if they had an estimated time of availability.

: Microsoft informed Core Security they would keep us updated.

: Core Security requested Microsoft let us know once they made a decision.

They were still reviewing it to determine if they would address it in a security release.

: Microsoft informed Core Security that they were able to reproduce the issue.

#Windows media center file location update

: Core Security requested Microsoft provide a status update and confirmation of the reported bug.

: Microsoft cased the report under MSRC 31305.

: Core Security sent Microsoft the draft version of the advisory including a PoC.

: Microsoft acknowledged receipt of the email and requested a draft version of the advisory.

: Core Security sent the first notification to Microsoft.

Proof of ConceptДЄ new file should be created with the name 'poc-microsoft.mcl' and with the following content: function do_upload(fname, data) upload_file('file:///C:/Windows/System32/calc.exe') 8. Those read files then can be uploaded to an arbitrary remote web server.ДЄlso note that, in order for the PoC to work, the value of the 'url' parameter must match the name of the MCL file. Unlike what happens when loading a local HTML file into Internet Explorer 11, the JS code included here will automatically run with no prompts, and it will be able to read arbitrary local files using the MSXML2.XMLHTTP ActiveX object. The proof-of-concept shows an MCL file with embedded HTML + JS code, referencing itself in the 'url' parameter.

The ehexthost.exe binary, part of Windows Media Center, loads the given URL into an embedded instance of Internet Explorer running in the local machine zone, but it doesn't opt-in for the FEATURE_LOCALMACHINE_LOCKDOWN IE security feature, therefore this situation can be leveraged by an attacker to read and exfiltrate arbitrary files from a victim's local filesystem by convincing him to open a malicious MCL file. Technical Description / Proof of Concept Code The publication of this advisory was coordinated by JoaquГn RodrГguez Varela from the Core Advisories Team. This vulnerability was discovered and researched by Francisco Falcon from Core Exploits Team. Microsoft posted the following Security Bulletin: MS15-134 6. Vendor Information, Solutions and Workarounds

Other versions are probably affected too, but they were not checked.ДҐ.

#Windows media center file location windows 7

Windows 7 for ењ†4-based Systems Service Pack 1 (with Internet Explorer 11 installed).

The 'application' tag in Microsoft Windows Media Center link files (.mcl extension) can include a 'run' parameter, which indicates the path of a file to be launched when opening the MCL file, or a 'url' parameter, which indicates the URL of a web page to be loaded within the Media Center's embedded web browser.ДЄ specially crafted MCL file having said 'url' parameter pointing to the MCL file itself can trick Windows Media Center into rendering the very same MCL file as a local HTML file within the Media Center's embedded web browser.
