K62532311: jQuery vulnerability CVE-2012-6708

Security Advisory

Original Publication Date: Nov 28, 2018

Security Advisory Description

jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The
jQuery(strInput) function does not differentiate selectors from HTML in a
reliable fashion. In vulnerable versions, jQuery determined whether the input
was HTML by looking for the '<' character anywhere in the string, giving
attackers more flexibility when attempting to construct a malicious payload. In
fixed versions, jQuery only deems the input to be HTML if it explicitly starts
with the '<' character, limiting exploitability only to attackers who can
control the beginning of a string, which is far less common. (CVE-2012-6708)


This vulnerability allows an authenticated user to perform an unauthorized
