Gallery 1.3.3

Vulnerable: gallery version 1.3.3 (other versions not tested)
Url: gallery.sf.net

Local exploit.

Gallery has a security hole where any other user on the same webserver
can create, modify or destroy photos in a given album directory.

Also Gallery requires that you turn off safe mode.

Each gallery setup needs a temp directory and an album directory.

Gallery accesses the album directory in a manner that requires
permissions of 755.

eg:
drwxr-xr-x   5 www   wheel   512 Feb  9 16:02 albums

and inside albums: 
ls -l
total 16
drwxrwxr-x  2 www  wheel  3584 Feb  9 16:19 album01
drwxrwxr-x  2 www  wheel  5120 Feb  9 16:25 album02
-rw-r--r--  1 www  wheel    65 Feb  9 16:02 albumdb.dat
-rw-r--r--  1 www  wheel    65 Feb  9 16:02 albumdb.dat.bak
-rw-r--r--  1 www  wheel     0 Feb  9 14:05 albumdb.dat.lock
-rw-r--r--  1 www  wheel    11 Feb  9 15:42 serial.dat

As a result anyone who has ever set up a gallery before can just have a
cgi running as user www (or whatever user apache is running as) move
files around.

This can be exploited with everything from SSI, perl to even php.

So on shared hosting gallery is a bad idea.


There is no fix for this as of this time.
This is a product of poor default web application security design.
