but why would the server accept the link from you ? i mean it already have it

[@BePracticalTech]

Thanks for asking this question. Let's try to understand from the developer's perspective. Many times the file will get uploaded at the third party services(like s3 buckets etc). Suppose the user wants to re upload the file, In this case the file needs to be uploaded on the server again and the new link needs to be stored again. To speed up this process, many times developers fetch the link at the client side so that if they want to re upload the file, they can just modify the data at the client side rather than editing the data in db. Once the client is done with their file upload, they can finally click on the submit button and then the final link will be uploaded in the database. Hope you understand

@@BePracticalTech thx i got it even that seems untypical behavior

[@BePracticalTech]

Glad you understand! I think every vulnerability is an untypical behavior. 😉

So, If I upload a malicious JPG file to the web application then the server can not validate right? like attacker using jpg to exploit or something malicious like that. (in png image cmd command)
Then it can be a bug?
So, in any application where uploading features going on, and server don't validating the input file then it can be a bug??

[@joy3658]

But what would be the scenerio or response like if server was validate that?

[@BePracticalTech]

Please read the pinned comment to understand.

Haii, watching your videos from the Start, learned a lot., now can you do a video on, where we have to look a particular bug, for example What are the bug we can look in registration, and what are the possible parameter for particular bugs 🫶🏻

[@r3plican]

it is same as redirect vuln?

[@BePracticalTech]

Yes, it is kind of similar to open redirection
