Allowed attachment file extensions

Post by Octocontrabass »

At some point (probably during the upgrade) it seems like the list of allowed file extensions for attachments was changed. The current list of allowed file extensions is... interesting, but It's easy enough to rename files to one of the allowed extensions before uploading.

It turns out, though, you also can't download attachments with forbidden extensions. Here's a random example I stumbled across.

I don't know if changing the list of allowed file extensions would be worth the effort, but I figured I'd point it out anyway.

It let me download that without warning or error. No idea why.

I can confirm that the ld and asm files are now hidden. Honestly, not sure what an extension filter is supposed to do if you can still upload all files by just renaming them.

Derp! Sorry, no; ld and asm are blocked without even a link.

It's certainly close to just being security theater, but not entirely there. I think it's good for boards with non-technical users, particularly new non-technical users. Do we gain anything from it at all?

I've added ld and asm to the allowed list.
