Title:Moodle File Disclosure Vulnerability (Mar 2009)
Summary:Moodle is prone to a file disclousure vulnerability.
Description:Summary:
Moodle is prone to a file disclousure vulnerability.

Vulnerability Insight:
An input filter for TeX formulas can be exploited to disclose
files readable by the web server. This includes the moodle configuration file with all
authentication data and server locations for directly connecting to backend database.

TeX filter by default is off and in case of being activated mostly no complete LaTeX environment
on a server system will be available.

Affected Software/OS:
Moodle versions 1.6.x prior to 1.6.9, 1.7.x prior to 1.7.7,
1.8.x prior to 1.8.9 and 1.9.x prior to 1.9.5.

Solution:
Several alternatives:

1) deactivate TeX filter, if not needed

2) use more restrictive mimetex program for rendering

3) change LaTeX configuration (set 'openin_any=p' for paranoid!)

or upgrade to latest development version where patch should be applied by now.

CVSS Score:
4.3
