CVE-2017-15684

Vulnerability

Overview

CVE-2017-15684 is a directory traversal vulnerability in Crafter CMS Crafter Studio version 3.0.1. The flaw allows an unauthenticated attacker to read arbitrary files from the underlying operating system by manipulating file path parameters. The root cause is insufficient validation of user-supplied input when accessing file resources, enabling path traversal sequences such as ../ to escape the intended directory [1].

Exploitation

The vulnerability can be exploited remotely without authentication. An attacker only needs network access to the Crafter Studio web interface. By crafting a specially crafted HTTP request containing directory traversal patterns in the URL or request parameters, the attacker can navigate the filesystem outside the web root. No special privileges or user interaction are required [1].

Impact

Successful exploitation allows an attacker to read sensitive files from the server, including configuration files, application source code, credentials, or other data stored on the filesystem. This could lead to further compromise of the system or disclosure of confidential information [1].

Mitigation

As of the publication date, no official patch or advisory from Crafter CMS has been identified. Users of Crafter Studio 3.0.1 should consider applying strict access controls, such as network segmentation or web application firewall rules, to limit exposure. Upgrading to a newer, patched version of Crafter CMS is recommended if available [1].
