TITLE:
Claroline Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA15161

VERIFY ADVISORY:
http://secunia.com/advisories/15161/

CRITICAL:
Highly critical

IMPACT:
Cross Site Scripting, Manipulation of data, Exposure of sensitive
information, System access

WHERE:
>From remote

SOFTWARE:
Claroline 1.x
http://secunia.com/product/4607/

DESCRIPTION:
Kevin Fernandez and Mehdi Oudad has reported some vulnerabilities in
Claroline, which can be exploited by malicious people to conduct
cross-site scripting and SQL injection attacks, manipulate and
disclose sensitive information and potentially compromise a
vulnerable system.

1) Some input isn't 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 a vulnerable site.

Examples:
http://[victim]/claroline/tracking/toolaccess_details.php?tool=[code]
http://[victim]/claroline/tracking/user_access_details.php?cmd=doc&data=[code]
http://[victim]/claroline/calendar/myagenda.php?coursePath=[code]

2) Some input isn't properly sanitised before being used in a SQL
query. This can be exploited to manipulate SQL queries by injecting
arbitrary SQL code.

Examples:
http://[victim]/claroline/user/userInfo.php?uInfo=[code]
http://[victim]/claroline/tracking/exercises_details.php?exo_id=[code]

3) Some input validation errors in the scripts
"claroline/document/document.php" and
"claroline/learnPath/insertMyDoc.php" can be exploited to upload,
disclose, copy, move or delete arbitrary files via directory
traversal attacks.

Successful exploitation requires project administration privileges
(e.g. teachers).

4) Certain unspecified input isn't properly verified, before it is
used to include files. This can be exploited to include arbitrary
files from external and local resources.

The vulnerabilities have been reported in version 1.5.3, 1.6 beta and
1.6 Release Candidate 1. Other versions may also be affected.

SOLUTION:
Update to version 1.54 or 1.6.
