DESCRIPTION:
Some vulnerabilities have been discovered in TomatoCMS, which can be
exploited by malicious users to conduct script insertion attacks and
compromise a vulnerable system and by malicious people to conduct
cross-site scripting and cross-site request  forgery attacks.

1) Input passed via the "keyword" and "bannerid" parameters to
index.php/admin/ad/banner/list is not properly sanitised before being
returned to the user. This can be exploited to execute arbitrary HTML
and script code in the users browser in context of the affected
site.

2) Input passed via the "title" and "answers" parameters to
index.php/admin/poll/add 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 requires "Create new poll" permissions.

3) Input passed via the "name" parameter to
index.php/admin/category/add 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 requires "Create new category" permissions.

4) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. change the administrative
password by tricking a logged-in administrative user into visiting a
malicious web site.

5) Input passed via the "keyword" and "article-id" parameters to
index.php/admin/news/article/list, the "keyword" parameter to
index.php/admin/multimedia/set/list, the "keyword" and "fileId"
parameters to index.php/admin/multimedia/file/list, and the "name",
"email", and "address" parameters to index.php/admin/ad/client/list
is not properly sanitised before being returned to the user. This can
be exploited to execute arbitrary HTML and script code in the users
browser in context of the affected site.

6) An error exists in the validation of uploaded image files while
adding a new article. This can be exploited to upload arbitrary files
inside the webroot and e.g. execute arbitrary PHP code.

Successful exploitation of this vulnerability requires "Add new
article", "Upload file to server", and "Browse uploaded files"
permissions.

The vulnerabilities are confirmed in version 2.0.6. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised. Do
not browse untrusted websites or follow untrusted links while logged
in to the application. Grant only trusted users "Add new article",
"Upload file to server", and "Browse uploaded files" permissions.
