DESCRIPTION:
David Vieira-Kurz has discovered some vulnerabilities in ConPresso,
which can be exploited by malicious people to conduct session
fixation and script insertion attacks.
1) An error in the handling of sessions can be exploited to hijack
another user's session by tricking the user into logging in after
following a specially crafted link.
2) Input passed via the URL to _admin/frame_titel.php is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.
The vulnerabilities are confirmed in version 4.0.7. Other versions
may also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised. Do
not follow links from untrusted sources.
