TITLE:
e107 Two Vulnerabilities

SECUNIA ADVISORY ID:
SA39013

VERIFY ADVISORY:
http://secunia.com/advisories/39013/

DESCRIPTION:
Secunia Research has discovered two vulnerabilities in e107, which
can be exploited by malicious users to conduct script insertion
attacks or to compromise a vulnerable system.

1) An error exists in the handling of file uploads for avatar or
photograph images. This can be exploited by to upload and execute
arbitrary PHP code via a specially crafted image file with an
".php.filetypesphp" extension.

Successful exploitation of this vulnerability requires that "Public
Uploads" are disabled (default), but uploads for avatar or photograph
images for users are enabled, and a certain server configuration (e.g.
an Apache server with the "mod_mime" module installed).

2) Input passed via the "content_heading" parameter to
e107_plugins/content/content_manager.php while creating new content
is not properly sanitised before being displayed to the user. This
can be exploited to insert arbitrary HTML and script code, which will
be executed in a user's browser session in context of an affected site
when the malicious data is being viewed.

Successful exploitation of this vulnerability requires authentication
and that the Content Management plugin is enabled.

The vulnerabilities are confirmed in version 0.7.19. Prior versions
may also be affected.

SOLUTION:
Update to version 0.7.20.
