Vulnerability CVE-2021-27272


Published: 2021-03-29   Modified: 2021-03-30

Description:
This vulnerability allows remote attackers to delete arbitrary files on affected installations of NETGEAR ProSAFE Network Management System 1.6.0.26. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the ReportTemplateController class. When parsing the path parameter, the process does not properly validate a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-12123.

Type:

CWE-22

(Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'))
