Radio TV Stage Test Wowza Backdoor


Background info, not necessary for testing:
We discovered an unfortunate backdoor in the wowza plugin. The problem goes as follows When summa requests to play a file, they send two parameters

  1. rmtp://iapetus/doms?skldfhskdfhdskjhfgskd
  2. flv:filename.flv

Now, the doms plugins decode the right filename from 1, but if the doms plugin is not on the classpath, the execution just contiues onto the flvplayer. The flv player just reads the value of 2, and attempts to play it. If it is configured to request files from the correct folder, it will play. The simple workaround is to have the wowza config point to a wrong folder (so that flvplayer cannot play on it's own) but to have the domsplugins be able to decode the correct location of the video file. Thus, the video should not be played unless the domsplugin is actually run.


Test no backdoor for doms plugin

  1. Find a shard pid of a recording that has already been trancoded.
  2. Open a simple-flash-player (that came with Wowza).
  3. POST http://alhena:7980/authchecker/issueTicket?username=172.18.243.211&url=http://www.statsbiblioteket.dk/doms/shard/uuid:f39fa734-f78b-412a-aa81-23e08e18e1af 

  4. Enter in the simple-flash-player (first field) : rmtp://iapetus:<PORTNUMBER>/doms?shard=http://www.statsbiblioteket.dk/doms/shard/<INSERT_UUID_HERE>&ticket=<INSERT_TICKET_HERE>

  5. Enter in the simple-flash-player (second field) : flv:<INSERT_UUID_HERE>.flv

  6. Verify that the video is played.
  7. Go into the services/doms_wowza_vhost folder of iapetus

  8. mv applications/lib .

  9. Restart wowza
