CVE-2017-15681

Vulnerability

Details CVE-2017-15681 is a directory traversal vulnerability in Crafter CMS Crafter Studio version 3.0.1. The flaw allows an attacker to traverse directories on the server, potentially overwriting critical system files. This vulnerability is present in the Crafter Studio component of the Crafter CMS platform [1].

Exploitation

No authentication is required to exploit this vulnerability. An unauthenticated attacker can send crafted HTTP requests to the affected endpoint, using path traversal sequences to access files outside the intended web root. Due to the lack of input validation, the attacker can overwrite arbitrary files on the operating system [1].

Impact

Successful exploitation can lead to complete compromise of the server. By overwriting executable files such as web application code or system binaries, an attacker can achieve remote code execution (RCE). This grants the attacker the same privileges as the application, potentially leading to full system control [1].

Mitigation

As of the publication date, no patch or workaround has been officially confirmed. Administrators should restrict network access to the Crafter Studio interface and monitor for unusual file modifications.
