Deeper analysis

This vulnerability is a path traversal flaw, tracked as CVE-2022-2560 and originally ZDI-CAN-17481, that affects EnterpriseDT CompleteFTP Server version 22.1.0. The issue resides in the HttpFile class, which fails to validate user-supplied paths before performing file operations, enabling deletion of arbitrary files on the server.

Remote attackers can exploit the flaw without authentication over the network. Successful exploitation grants the ability to delete files while running in the context of the SYSTEM account, resulting in high impact to integrity and availability as reflected in the CVSS 9.1 score and CWE-22 classification.

The associated Zero Day Initiative advisory ZDI-22-1032 details the vulnerability and is the primary public reference for affected installations.
