CVE-2017-17859

moderate-risk
Published 2017-12-27

Samsung Internet Browser 6.2.01.12 allows remote attackers to bypass the Same Origin Policy, and conduct UXSS attacks to obtain sensitive information, via vectors involving an IFRAME element inside XSLT data in one part of an MHTML file. Specifically, JavaScript code in another part of this MHTML file does not have a document.domain value corresponding to the domain that is hosting the MHTML file, but instead has a document.domain value corresponding to an arbitrary URL within the content of the MHTML file.
