Stefan Schurtz has discovered a vulnerability in SaltOS, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input appended to the URL after lib/phpexcel/PHPExcel/Shared/JAMA/docs/download.ph p is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerability is confirmed in version 3.1 build 4941. Other versions may also be affected.

Hi users.

The issue was fixed in the nightly SaltOS-3.1-5694.noarch.tgz (2012-08-14). The bug allows to use an unused php file (code/lib/phpexcel/PHPExcel/Shared/JAMA/docs/downl oad.php) to do the attack. If you want to fix the issue, you only need to remove the entire directory code/lib/phpexcel/PHPExcel/Shared/JAMA/docs (examples and tests directories too is recomended).
