Which means any user can +create a stylesheet and have it be used, without needing permission to +upload arbitrary files. That probably needs to be fixed; one way would be +to mandate that the `srcfile` has a `.xsl` extension. + +Secondly, if an attacker is able to upload a stylesheet file somehow, could +this be used to attack the server where it is built? I know that xslt is +really a full programming language, so I assume at least DOS attacks are +possible. Can it also read other arbitrary files, run other programs, etc? +--[[Joey]] |
