    I don’t know of anyway to ‘bypass’ it. You will likely have to be logged in with an account that has sufficient permission to view the file/path you’re requesting.

    you wont be able to bypass 403 forbidden, but you might can get the contents you are looking for by brute forcing. it will depends on the configuration and security in place but it worth giving a try. for example, domainname.com/upload could display 403 forbidden but domainname.com/upload/database.sql.bk might allow you to download the file. misconfigured server can give you surprises.

    Umm.. Oh ok.. There is nothing that can’t be bypassed if your doing any sort of course on here to do with IT Security you need to know 1 thing.. Nothing is impossible.

    You could bypass 403.. All this means is you don’t have authorization to access the directory. You could attempt social engineering to gain root, Find another way in via another directory then gain root so that you can have access to that directory, You could look into LFI’s or RFI’s or maybe xss or sql injection attacks. There is also blind guessing which is hard but possible by just guessing sub directories or files to gain access like javasabin said.

    Other ways is by looking at the protocols and then setting up a virtual test environment with the same web server and protocols then fuzzing them to create your own vulnerability to bypass it. If its Microsoft then look into Microsoft permissions and policies, if its Apache then look into the config permissions and group setups..etc Anything is possible just need to research it and practice trial and error.

    As Security Girl states, a 403 simply means you are not authorised to view the content. The interesting part is WHY you are not allowed to view the contents. If you do not have the requested credentials, there are tools that can try and brute force them for you. However, there are a lot of other reasons for a 403, it does not have to be an authentication issue. Simply having an IP address from a different subnet can be reason enough for a 403 response. You must find the reason for a 403 first, then choose your method of attack.

    Dear ashiq_ali21,

    Many things can trigger 403 errors, I.e: web application firewalls (WAFs) and intrusion detection systems (IDS’); depending on the nature of your attacks, there are a myriad of ways to bypass said security measures. SQLi, RFI, LFI, and most other attack vectors have different routes you can take to carry out an attack.

    I’m not sure why you’re encountering the 403 forbidden (not sure what you’re trying to do), but I’ll use LFI (local file inclusion) exploits to illustrate my point. Many IDS’, especially signature based, forbid specific phrases to thwart attacks, I.e: ../../../../etc/passwd or ../../../../var/logs might be filtered. To bypass an IDS, one can encode the banned phrase in hex or any other encoding type, for example: ../../../../etc/passwd now becomes 2E2E2F2E2E2F2E2E2F2E2E2F6574632F706173737764 and is able to slip by the IDS. It’s kind of like trying to exploit a system that speaks English and Spanish, but only English malicious keywords are banned and the system doesn’t filter Spanish keywords – just use Spanish, right? This method can be utilized for most URL injection vectors. My example is very vague, but I’m sure you can use your grasp the concept.

    You can’t bypass 403 forbidden. If it is ip restriction, then you need to access the application from that IP. If it is username and password, then you need to get a username and password.
    You should do your reconnaissance before you start you attack. There are 4 steps in pen.testing.

    You should make your question more clear..

    If you want to bypass symlink just create a htaccess in your symlink directory and write only “Option all” in your htaccess code.. Boom bypassed

    I know I am not authorized to view the page I’m trying to access. When I go to a subdirectory that I know exists it gives me a 404 error. Anyone know how to get in?

    Hi there:

    My 403 error is due to block by administrator no only to an specific IP address but geographically.

    Could still be accessible?

    Thanks
