Interesting.
It looks like someone probing for a RoundCube Webmail vulnerability:
http://www.h-online.com/security/RoundCube-vulnerability-allows-injection-o
f-arbitrary-scripting-code--/news/112330
The interesting thing about the source is that it appears to be originating
from a Brazilian High Performce Computing Facility:
AS | IP | AS Name
1916 | 200.19.191.98 | Rede Nacional de Ensino e Pesquisa
200.19.191.98 -PTR-> oros.cenapadne.br

Maybe a compromised host? Who knows.

p.s. You can always toss these types of things over on the funsec mailing
list:
https://linuxbox.org/cgi-bin/mailman/listinfo/funsec
There folks over on funsec which can handle reports of this nature, and
actually engage the appropriate parties in Brazil...
