OpenNMS HTTP Response Splitting Vulnerability
---------------------------------------------

Vulnerability Information
-------------------------
Remotely exploitable: Yes
Locally exploitable: No
Affected versions:
OpenNMS 1.5.93-1
Other versions may also be affected.

Vulnerability Details
---------------------
An input validation problem exists within OpenNMS which allows injecting
CR (carriage return - %0D or \r) and LF
(line feed - %0A or \n) characters into the server HTTP response header,
resulting in a HTTP Response Splitting[1]
vulnerability.
This vulnerability is possible because the application fails to validate
user supplied input, returning it
un-sanitized within the server HTTP response header back to the client.
This vulnerability not only gives attackers control of the remaining
headers and body of the server response, but
also allows them to create additional responses entirely under their
control.
Attacker-supplied HTML or JavaScript code could run in the context of
the affected site, potentially allowing an
attacker to steal cookie-based authentication credentials, control how
the site is rendered to the user, and
influence or misrepresent how web content is served, cached, or
interpreted. Other attacks are also possible.






Proof-of-Concept
----------------

Header injection:
http://server/opennms/event/query?%0D%0AInjectedHeader:%20BugSec

Server response:
HTTP/1.1 302 Moved Temporarily
Date: Thu, 25 Sep 2008 11:30:05 GMT
Server: Apache/2.2.3
Location: http://server/opennms/event/list?
InjectedHeader: BugSec=
Content-Length: 0
Connection: close
Content-Type: text/plain; charset=UTF-8


HTTP Response Splitting:
http://server/opennms/event/query?%0D%0AContent-Length:%200%0D%0A%0D%0AHTTP/1.1%20200%20OK%0D%0AContent-Type:%20text

OpenNMS Cross-Site Scripting Vulnerabilities
--------------------------------------------

Vulnerability Information
-------------------------
Remotely exploitable: Yes
Locally exploitable: No
Affected versions:
Â•    OpenNMS 1.5.93-1
Other versions may also be affected.

Vulnerability Details
---------------------
An input validation problem exists within OpenNMS which allows execution
of arbitrary client-side code resulting in
a cross-site scripting vulnerability.
An attacker may leverage cross-site scripting vulnerability to have
arbitrary script code executed in the browser of
an unsuspecting user in the context of the affected site. This may
facilitate the theft of cookie-based
authentication credentials as well as other attacks.
