Cisco Firepower Threat Defense Software Command File Overwrite (cisco-sa-ftd-file-overwrite-XknRjGdB)

medium Nessus Plugin ID 149298
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote device is missing a vendor-supplied security patch


According to its version and configuration, the Cisco Firepower Threat Defense (FTD) Software running on the remote device is affected by a file overwrite vulnerability due to insufficient validation of user input. An authenticated, local attacker can exploit this, by logging in and issuing a crafted command, in order to overwrite files.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
