Open redirect vulnerability in Snipe-IT allows attackers to redirect users to malicious sites via unvalidated HTTP Referer header stored in session variable.
When the user clicks "Save", the application:
1. Processes the form
2. Checks redirect_option (if set to 'back')
3. Calls Helper::getRedirectOption()
4. Retrieves back_url from session: https://evil.com/phishing?target=snipeit
5. Executes redirect()->to($backUrl)
6. User is redirected to attacker's site
This would still require session poisoning, so the actual practical threat here is minimal.
