Acronis Backup Cloud: update permissions for Acronis Agent for Linux files to prevent unprivileged users accessing the files

We have recently identified a security issue within Acronis Agent for Linux installations that may potentially allow unprivileged users to access Agent logs and backup data.

We have identified that these files and directories have excessive read permissions (allowing users who are not functioning as backup operators read the files) and recommend to deny read permissions to all users other than 'acronis' group members to these files:

/var/lib/Acronis/BackupAndRecovery/OnlineBackup/Default/username.crt
/var/lib/Acronis/BackupAndRecovery/MMS/user.config
/var/lib/Acronis/BackupAndRecovery/MMS/AccessVault/raw/*
