TITLE:
dotProject Script Insertion Vulnerabilities

SECUNIA ADVISORY ID:
SA38125

VERIFY ADVISORY:
http://secunia.com/advisories/38125/

DESCRIPTION:
Justin C. Klein Keane has discovered some vulnerabilities in
dotProject, which can be exploited by malicious users to conduct
script insertion attacks.

1) Input passed to the "project_name", "project_url",
"project_demo_url", and "project_description" parameters in index.php
(when "m" is set to projects" and "a" is set to "addedit") is not
properly sanitised before being used. This can exploited to insert
arbitrary HTML and script code, which will be executed in a user's
browser session in the context of an affected site if the malicious
project details are viewed.

2) Input passed to the "task_name", "task_related_url", and
"task_description" parameters in index.php (when "m" is set to
"tasks", "a" is set to "addedit", and "task_project" is set) is not
properly sanitised before being used. This can exploited to insert
arbitrary HTML and script code, which will be executed in a user's
browser session in the context of an affected site if the malicious
task details are viewed.

3) Input passed to the "task_log_name", "task_log_related_url", and
"task_log_description" parameters in index.php (when "m" is set to
"tasks", "a" is set to "view", "tab" is set to "1", and "task_id" is
set) is not properly sanitised before being used. This can exploited
to insert arbitrary HTML and script code, which will be executed in a
user's browser session in the context of an affected site if the
malicious task log details are viewed.

4) Input passed to various parameters in index.php (when "m" is set
to "contacts" and "a" is set to "addedit") is not properly sanitised
before being used. This can exploited to insert arbitrary HTML and
script code, which will be executed in a user's browser session in
the context of an affected site if the malicious contact details are
viewed.

Successful exploitation of vulnerabilities requires the "Project
Worker" role.

The vulnerabilities are confirmed in version 2.1.3. Other versions
may also be affected.

SOLUTION:
The vulnerabilities are fixed in the GIT repository.

Grant only trusted users the "Project Worker" role.
