It's possible due to the fact, that some web browsers incorrectly display contents of the url bar while rendering pages based on the 'data:' URL scheme (RFC 2397). Only the ending of the URL is displayed. Padding the URL with whitespaces allows an attacker to insert an arbitrary content into the browser url bar. http://alt.swiecki.net/oper1.html Tested with: * Opera 9.21 on Win 2003SE and Win XPSP2 * Opera 9.21 on Linux * Konqueror 3.5.7 on Linux Pictures taken on my systems (using 1024x768 dekstop resolution) http://alt.swiecki.net/operalin.png http://alt.swiecki.net/operawin.png http://alt.swiecki.net/konq.png Successfull attack depends on the proper construction of the 'data:' URL. An algorithm could utilize JS document.body.clientWidth/Height properties to calculate the best url padding for the given browser. PS. Sometimes Opera web browser displays the beggining of the 'data:' URL (correct behaviour), e.g. during browser startup with immediate redirect to the last visited page. -- Robert Swiecki --------------------------------------------------------- jer@gentoo.org 2007-07-19 17:38:09 0000 http://www.opera.com/docs/changelogs/linux/922/ says: * Fixed an issue that could occur when removing a specially prepared torrent transfer, as reported by iDefense. See the advisory[1]. * Fixed a data leak issue when using canvas.createPattern, as reported by Philip Taylor. See the advisory[2]. * Prevented an issue where data URLs could be used to display the wrong address in the address bar. See the advisory[3]. * Improved the display of long domain names in authentication dialogs. Long domain names will now scroll instead of using ellipsis. See the advisory[4]. * Added Trustcenter class 3 G2 root certificate. * Fixes for a problem with certificate import from PKCS #7 Signed and Netscape Multicert files. www-client/opera/opera-9.22.ebuild is in the tree!
