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 Credit: This issue was identified by Andreas Lindh Apache OpenMeetings Team -- WBR Maxim aka solomax
