HTC OBEX FTP directory traversal
|htc-obexftp-directory-traversal (48124)||Medium Risk|
HTC devices running Microsoft Windows Mobile could allow a remote authenticated attacker to traverse directories on the system caused by an error in obexfile.dll. An attacker could send a specially-crafted URL request to the OBEX FTP server containing "dot dot" sequences using forward-slash or backslash characters (../ or ..\) to traverse directories and upload files to folders or download files or directories outside the default Bluetooth shared folder.
Apply the hotfix for this vulnerability, available from the HTC Web site. See References.
