NETGEAR ProSAFE Plus Configuration Utility vulnerable to improper access control
Overview
ProSAFE Plus Configuration Utility is vulnerable to improper access control.
Products Affected
- ProSAFE Plus Configuration Utility prior to 2.3.29
Description
ProSAFE Plus Configuration Utility provided by NETGEAR is a Windows application to configure and manage NETGEAR's ProSAFE Plus and Click Switches. An operator uses the utility to login and configure NETGEAR switches.
When the utility is invoked, it starts listening on a certain port for SOAP requests. The utility executes configuration tasks for switches according to the SOAP requests.
The utility accepts connections from network, hence unintended operation may be conducted on the switches through the utility (CWE-284).
Impact
The Configuration Utility may be manipulated by some unexpected SOAP requests to configure the connected switch.
Solution
Update the Software
Update to the latest version according to the information provided by the developer.
