FreeBSD : rssh -- file name disclosure bug (a4815970-c5cc-11d8-8898-000d6111a684)
Medium Nessus Plugin ID 36857
SynopsisThe remote FreeBSD host is missing a security-related update.
Descriptionrssh expands command line parameters before invoking chroot. This could result in the disclosure to the client of file names outside of the chroot directory. A posting by the rssh author explains :
The cause of the problem identified by Mr. McCaw is that rssh expanded command-line arguments prior to entering the chroot jail. This bug DOES NOT allow a user to access any of the files outside the jail, but can allow them to discover what files are in a directory which is outside the jail, if their credentials on the server would normally allow them read/execute access in the specified directory.
SolutionUpdate the affected package.
