Write Permissions Security Issues - end user headaches!

My web host requires a support ticket to be submitted in order for folder's to be given write permissions. Folder's with write permissions have script execution disabled.
This creates problem's for the end user (me) when installing many pre-built applications, be it PHP or ASP.

IS it common on all shared hosting server's to function this way?

I would really like a control panel to turn on my own write permissions, I am running pre-built applications when I can, and don't have the knowledge to re-write the applications parameters to run on Windows servers sometimes. My host also lacks phpMyAdmin or any mySQL admin panel.
I am stuck in a Windows hosting world/career, and am looking for an open source CMS, I'm just not to sure about dotNetNuke.
It's a little bit stuffy over there at the dotNetNuke forum's exchange.

What should I do?

Hi,

I've never had to use a shared hosting env but I would imagine this is fairly standard. If you could remotely write and execute on a webserver there is nothing to stop you write an exploit up there and then execute it on the machine. Ie taking control of the server, damaging others users files, using it as a source for a DOS/DDOS attack.

Displeaser

My hosting company, www.crystaltech.com has offered a control panel for file permission settings for 4 or 5 years now. You don't need to bother support for file permissions, dns settings, etc.

Plus on your windows site you get php & mysql as well as asp. You can run mambo and other opensource php cms on the shared hosting servers.
