Vulnerability title: Insufficient Input Validation By IO Slaves In KDE e.V. KDE CVE: CVE-2014-8600 Vendor: KDE e.V. Product: KDE Affected version: kwebkitpart <= 1.3.4, kde-runtime <= 4.14.3, kio-extras <= 5.1.1 Fixed version: Contact distribution vendor Reported by: T. Brown and D. Burton Details: Whilst investigating how KDE handles custom protocols, it was discovered that a number of the protocol handlers (referred to as IO slaves) did not satisfactorily handle malicious input. It is possible for an attacker to inject JavaScript by manipulating IO slave URI such that the JavaScript from the manipulated request is returned in the response. Example IO slaves that trigger this behaviour include: zip trash tar thumbnail smtps smtp smb remote recentdocuments nntps nntp network mbox ldaps ldap fonts file desktop cgi bookmarks ar The following code will trigger all vulnerable IO slaves: for x in /usr/share/kde4/services/*.protocol do proto=`basename $x | cut -f 1 -d\.` kfmclient newTab "$proto://hhdhdhhdhdhdh.google.com/\"><script>alert(\"$proto\"+document.domain);</script>" done Further details at: https://www.portcullis-security.com/security-research-and-downloads/security-advisories/cve-2014-8600/ Copyright: Copyright (c) Portcullis Computer Security Limited 2014, All rights reserved worldwide.
