Lab: SQL injection vulnerability in WHERE clause allowing retrieval of hidden data

Dawid | Last updated: Apr 17, 2024 09:42PM UTC

Hi, referring to the lab I wrote in subject, I am following lab solution and either I do something wrong or there is some bug. I am on the Tech Gifts page, and trying this address directly from my browser (blablabla=some characters only for this lab) : https://blablabla.web-security-academy.net/filter?category=Tech+gifts'+OR+1=1-- trying by encoding html https://blablabla.web-security-academy.net/filter?category=Tech+gifts'%2bOR%2b1%3d1-- by repeater GET /filter?category=Accessories'+OR+1%d1-- HTTP/2 tried only ' OR 1=1-- etc. but no results. and I still get http 500 - internal server error. Do I do something wrong? Can I ask someone to check it? Thank you in advance, Dawid.

Hi Dawid We have tested the lab and can confirm that it works as intended. I have added a screenshot showing the changes I made to Repeater to solve the lab: https://snipboard.io/Ab40WJ.jpg

Hi Dawid. Are you using the embedded browser to attempt the lab or an external browser? If you sent a normal request from Repeater, do you still receive the RST_STREAM error? For example, proxy the home page of that lab, send the request to Repeater, and then press send. Do you receive a response or get the RST_SREAM error message at the bottom of Repeater?

Hi Dominyque, I use firefox for that, but I don't have any issues with proxy, I configured it as PortSwigger asked - I don't experience other problems than only in this lab. If I send from repeater home page, everything is OK and I've got 200, please check below : https://snipboard.io/u4gaV0.jpg so seems like no browser issue. I tried it once again (firstly I checked it from the first path, server-side vulnerabilities) and now I can retry it in SQL injection (the same lab) but it still doesnt work and shows me lab not solved. That's crazy :D
