Description

Impact

Path Traversal is possible in Oro\Bundle\GaufretteBundle\FileManager::getTemporaryFileName.
With this method, an attacker can pass the path to a non-existent file, which will allow writing the content to a new file that will be available during script execution. The file will be deleted immediately after the script ends.

Or decorate Oro\Bundle\GaufretteBundle\FileManager::getTemporaryFileName in your customization and clear $suggestedFileName argument

    public function getTemporaryFileName(string $suggestedFileName = null): string
    {
        if ($suggestedFileName) {
            $suggestedFileName = basename($suggestedFileName);
        }

        return parent::getTemporaryFileName($suggestedFileName);
    }

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
