Toshiba printers use XML communication for the API endpoint provided by the printer. For the endpoint, XML parsing library is used and it is vulnerable to a time-based blind XML External Entity (XXE) vulnerability. An attacker can DoS the printers. An attacker can exploit the XXE to retrieve information. As for the affected products/models/versions, see the reference URL.
This issue is fixed in the version released on June 14, 2024 and all later versions.
Configurations
Workarounds
When connecting the MFPs and printers with an outer network such as the Internet, only operate it in a network environment protected by a firewall, etc. to prevent information from being leaked due to incorrect settings or avoid illegal access by unauthorized users.
