Incorrect default permissions in five Hitachi management products on Linux allow local users to read and write specific files. Hitachi has not identified the affected paths, permission bits, or process that assigns the unsafe defaults. Low-privileged local access is required; exposed files can be read or altered, and modification can interrupt affected services.
