NETGEAR · ProSAFE Network Management System

Summary

A path traversal flaw in the MibController class of NETGEAR ProSAFE Network Management System 1.6.0.26 lets the realName parameter be used in file operations without proper validation of the supplied path. A remote attacker with low-privilege authentication (which can be bypassed) and no user interaction can delete arbitrary files, producing a denial-of-service condition on the system.

Official description · CVE.org

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 MibController class. When parsing the realName 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-12122.
