CVE-2009-1171: Input Validation
First published: Mon Mar 30 2009(Updated: )
The TeX filter in Moodle 1.6 before 1.6.9+, 1.7 before 1.7.7+, 1.8 before 1.8.9, and 1.9 before 1.9.5 allows user-assisted attackers to read arbitrary files via an input command in a "$$" sequence, which causes LaTeX to include the contents of the file.
