Description:
Some vulnerabilities have been reported in Cybozu Office, which can be exploited to gain knowledge of sensitive information.

Successful exploitation requires a valid user account.
2) It is possible for anyone to gain knowledge of registered users and groups.
The vulnerabilities have been reported in version 6.5 (Build 1.2) for Windows. Prior versions may also be affected.

Update to version 6.6 (Build 1.3).
