Understanding Implications of Using X01

Understand how an authenticated user can change the value of an image ID in the image URL using an image-serving page.

When viewing a page containing image URLs using the x01 parameter, if an authenticated user knows the ID of a different image, they can view it by:

• Selecting Copy Image Address from the context menu on an existing image in the page,

• Creating a new browser tab and pasting the copied URL into the address bar,

• Manually modifying the x01=123456 to x01=98765, and pressing [Enter].

In Woods HR, where any authenticated user can view any break room photo, it’s no problem.
