WSTG-SESS-03
Testing for Session Fixation
Session fixation is an attack where the attacker sets a user's session ID to a known value. When the victim authenticates, the attacker can hijack their session using the pre-set session ID. This occurs when the application doesn't regenerate the session ID after authentication, allowing the attacker to maintain access with the original session token.
#!/bin/bash
# Test if session ID changes after authentication
TARGET="https://target.com"
# Get pre-auth session
echo "=== Getting pre-auth session ==="
pre_session=$(curl -s -c - "$TARGET/" | grep -oP "SESSIONID=\K[^;]+")
