2) Input validation error

EUVDB-ID: #VU23781

Risk: High

CVSSv4.0: 6.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2019-19374

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to insufficient validation of user-supplied input in "core/assets/form/form_question_types/form_question_type_file_upload/form_question_type_file_upload.inc". A remote attacker can delete arbitrary files from the server during interaction with the File Upload field type, when a custom form exists.

Note: This is related to an information disclosure issue within the File Upload field type that allows attackers to view the full path to uploaded files, including the product's web root directory.

Mitigation

Install updates from vendor's website.
