Description Michael Grandjean univentionstaff 2015-09-29 22:36:45 CEST 
Observed behaviour:
* http(s)://<fqdn-of-your-ucs>/statistic/ requires authentication
* http(s)://<fqdn-of-your-ucs>/statistic/ucs_0load-day.png does NOT require authentication

Expected behaviour:
* Everything under http(s)://<fqdn-of-your-ucs>/statistic/ requires authentication since this might be considered sensitive information


Caused by:
/var/www/statistic/.htaccess:

> SetenvIf Request_URI "(statistik/ucs.*\.png)$" allow
> SetenvIf Request_URI "(statistic/ucs.*\.png)$" allow

So all PNG files are readable by everyone. This goes back to Bug #22513 - is it still true that protecting the PNG files would break the UMC module?
Comment 1 Florian Best univentionstaff 2015-10-22 10:03:31 CEST 
We could move the serving of the file into the module backend (which doesn't yet exists). Then they aren't delivered by apache anymore and the files are only accessible via UMC ACL's.

There is a Customer ID set so I set the flag "Enterprise Customer affected".
