Yep, any PHP files uploaded to the configured directory will be treated as text! Just make sure there's no other vulnerabilities, e.g. one of the portswigger labs involves overwriting a web config file, with an insecure file upload.
Nope, you can definitely find it with other services, e.g. ASP(X) and JSP. Even if there is no opportunity for code execution, file upload vulnerabilities could be damaging in other ways!
If I upload system instead instead of file get contents, I can use linux commands. If I cat the secret file, I got another (sadly wrong) string. I can only solve this lap with file get contents, but why?
@@intigriti i have already contacted them through their email they asked for screenshots i've also sent them Actually 2 days ago i tried to solve it and got the flag i tried to submit it it was showing the same error i hope they will fix it
Im so in over my head, drowning, in a swimming pool filled up with android acid rain, and fake system app puke accompanied by invisible 3rd party montioring certificate authorities punching on me, i wasnt invited to that party and these cyber bullys wont let me univite myself or allow me to have a running windows machine. Barly allowed to have a half unalive skitzophrenic chromebook, Im not gonna go as far to say, well yes i am. Somebody is angry with me. And its not a bot at this point. Robots tee tee oil, this is human waste products, i dont recall being stung by a jelly fish. I live ,300 miles from salt water , OK i tried to make it colorful to get someone that can help someones ATTENTION and sadly this probably wont work. And no help or HELPFUL ADVICE IS ON THE WAY. YALL KNOW NONE OF THE ANTI THIS OR THAT WORKS, am i doomed from having a smooth running machine for eternity? Or am i doomed for eternity?
I uploaded the obfuscated php shell (exploit.php%00.jpg), and the server answered that the file had been uploaded but when I tried to request the uploaded php shell by right-clicking on the image icon and choosing the "Open in a new tab" functionality, I got a 404. I solved the lab by requesting the uploaded file stripped of the obfuscation, namely GET/files/avatars/exploit.php
If I add to dir:
php_flag engine off
Would't that prevent all the shenanigans?

Hello.
Is Web Upload Vulnerability only common found in PHP based website? How about in other programming languange? Thank you

Hmmm maybe just the way Portswigger designed this lab 😕
@intigriti aah, I got a concadinated string, very interesting. Thanks bro!
1) Upload file named test.php%00.jpg
2) Open it via path /files/avatars/test.php
Thank you 💯💯💯💯
Thank you!
it doesnt allow me to submit the flag
Seems like there is an error in recgnising the flag for this lab
Oh dear.. Maybe could wait for the lab to reset, if not ask in Portswigger discord server

You're not doomed mate! Keep calm and hack on! 💜
