Surveillance Report
2/2
According to the “Announcement”, there is a possibility that the administrator page of the
web-based management utility “TopAccess” site could be accessed without passwords by
using the released vulnerability.
As a result of surveillance, it was verified in the previous evaluation under the
responsibility of the Evaluation Facility that the access to the administrator page of
“TopAccess” does not affect the security functions of the TOE.
The details are described as follows;
From the administrator page of “TopAccess”, it is possible to change the time and date of
MFP clock as well as the expiration date for storing user document data, etc. The previous
evaluation did not examine whether it is possible to change those by using the released
vulnerability when accessing the administrator page of “TopAccess”.
Although the TOE has a function to automatically delete the stored user document data
after passing the expiration date, it specifies that the residual data after being deleted is
no longer recognized as an asset to be protected.
As with other functions which can be used from the administrator page of “TopAccess”, it is
reported that the previous evaluation by the Evaluation Facility verified there was no
effect on the security functions of the Target of Evaluation.
