The Web Framework Authenticated Command Injection Vulnerability and Management GUI Denial of Service Vulnerability could be mitigated by disabling management access to the affected system GUI.
Administrators can use the interfaceconifg
command to disable appliance management via the GUI. Alternatively, this can be done via the
GUI by editing the management interface properties under Network->IP
interfaces-> Edit and then selecting Disable Appliance Management.
Administrators can manage the affected system via SSH and command-line interface while GUI access is
disabled. However, not all commands and features may be available via command-line interface.
Administrators can also limit the attack surface by restricting IP addresses that can access the management interface. This can be
done using the adminaccessconfig
command and selecting IPACCESS
from the menu.
Administrator should also implement Cross-Site Request Forgery
protection if available on their platform and software release. This
will help limit the attack surface of the Web Framework Authenticated Command Injection Vulnerability, although it will not completely eliminate it.
The IronPort Spam Quarantine Denial of Service Vulnerability can be mitigated by disabling the end-user access to the ISQ service. Administrators can disable this access using the interfaceconfig
command. Alternatively, this can be done via the
GUI by editing the settings for Spam Quarantine under Monitor->Quarantines-> Edit and then unchecking the option "Enable End-User Quarantine Access".
Users will be unable to manage their safe list and block list while end-user access is disabled.
