I happen to have some non-standard applications running on port 80

(200.19.191.98 is the IP address of the attacking machine, not me)


Is this sort of information of use to anyone here?
Is the above an old vulnerability - since I don't run
 whatever it is probing for, I have not paid much attention to these.



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...
