CVE-2016-10140 - Auth bypass and Info disclosure - affects v1.30 and v1.29
==========================================================================
Contacted vendor on 08/11/2016

Apache HTTP Server configuration bundled with ZoneMinder allows a remote unauthenticated attacker to browse all directories
in the web root, e.g., a remote unauthenticated attacker can view all CCTV images on the server.

PoC: http://<serverIP>/events

Fix: https://github.com/ZoneMinder/ZoneMinder/commit/71898df7565ed2a51dfe76a1cf30ddb81fc888ba



CVE-2017-5595 - File disclosure - affects v1.xx - code from 2008
================================================================
Contacted vendor on 22/01/2017

File disclosure and inclusion vulnerability exists in ZoneMinder v1.30.0 due to unfiltered user-input being passed to readfile() in views/file.php which allows an authenticated attacker to read local system files (e.g. /etc/passwd) in the context of the web server user (www-data).

PoC: http://<serverIP>/zm/index.php?view=file&path=/../../../../../etc/passwd

Fix: https://github.com/ZoneMinder/ZoneMinder/commit/8b19fca9927cdec07cc9dd09bdcf2496a5ae69b3

No CSRF protection exists across entire web app.

PoC: The following html page silently adds a new admin user to Zoneminder if the admin user is already logged in.
