Description

Open redirect vulnerability in Snipe-IT allows attackers to redirect users to malicious sites via unvalidated HTTP Referer header stored in session variable.

Impact

  • Phishing: Redirect users to fake login pages to steal credentials
  • Session Hijacking: Redirect to attacker site that captures session cookies via JavaScript
  • Malware Distribution: Redirect to sites hosting malware or drive-by downloads
  • Reputation Damage: Users lose trust when redirected to malicious sites from legitimate application
  • Social Engineering: Use trusted Snipe-IT domain to increase phishing success rate

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.
