I was trying to exploit a client-side prototype pollution and nothing was working.
I figured out that if you try to use a script gadget by visiting a URL like this dirrectly:
https://example.com/#&__proto__[context]=<img/src/onerror%3dalert(1)>&__proto__[jquery]=x
will not work because the page will not load properly as the prototype pollution will break the page.
| this is a text file | |
| aaa | |
| aaaa | |
| bbb | |
| cccc | |
| sddd |
| { | |
| "sampleJSONProperty":"sample JSON value", | |
| "sampleJSONProperty2":"sample JSON value2" | |
| } |
| so, you can read WEB-INF/web.xml. how can you escalate this issue? | |
| [step 1]. try to read other common Java files such as WEB-INF/web-jetty.xml. | |
| use a specialized wordlist such as the following (from Sergey Bobrov/BlackFan): | |
| https://github.com/BlackFan/WEB-INF-dict/blob/master/web-inf.txt | |
| with time you can build your own wordlist adding files you've discovered over time. | |
| use Burp Intruder for this, it's perfect for this job. | |
| sort Intruder results by status code so you can see instantly which files were found. |
| database.yml | |
| database.yml_original | |
| database.yml~ | |
| database.yml.pgsql | |
| database.yml.sqlite3 | |
| config/database.yml | |

| An idea for a tool. | |
| So, going through Wayback archive we get thousands of links like the ones below. | |
| It's the same path and different values for GET parameters. | |
| A very useful tool would filter these using this algo: | |
| - for each link, parse the link with an URL parser: | |
| - create a hash from: hostname + path + (parameter names (without values) sorted). | |
| - save the hash in an array | |
| - for the next links, compute the hash | |
| - if the hash is in the array, ignore the link |
