Apache OpenMeetings 3.1.0 Path Traversal

`Severity: Moderate  
  
Vendor: The Apache Software Foundation  
  
Versions Affected: Apache OpenMeetings 1.9.x - 3.1.0  
  
Description:  
The Import/Export System Backups functionality in the OpenMeetings  
Administration  
menu (http://domain:5080/openmeetings/#admin/backup) is vulnerable to path  
traversal via specially crafted file names within ZIP archives. By uploading an  
archive containing a file named ../../../public/hello.txt will write  
the file “hello.txt”  
to the http://domain:5080/openmeetings/public/ directory. This could  
be used to, for example,  
overwrite the /usr/bin/convert file (or any other 3 rd party  
integrated executable)  
with a shell script, which would be executed the next time an image  
file is uploaded  
and imagemagick is invoked.  
  
All users are recommended to upgrade to Apache OpenMeetings 3.1.1
