Description

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

 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).
