Remote exploitation of a insecure permissions vulnerability in Sybase Inc.'s M-Business Anywhere could allow an attacker to execute privileged commands. This condition can result in account compromise. The Sybase M-Business platform provides a client for desktop and mobile phone device access to a backend M-Business Server. By default the M-Business Server allows a user to self-register and create their own account with limited permissions. A vulnerability exists in the web administration interface where by a regular user can log in and execute scripts meant for exclusive use by the 'admin' user, without requiring any further authentication.

It is possible for a regular user to list all registered users with the option to edit or change the password, as well as delete any user account by simply accessing a url. Additionally a regular user may create a new group or view the M-Business Server log files.
