Details

Christian Eibl discovered that the TeX filter in Moodle allowed any
function to be used. An authenticated remote attacker could post
a specially crafted TeX formula to execute arbitrary TeX functions,
potentially reading any file accessible to the web server user, leading
to a loss of privacy. (CVE-2009-1171, MSA-09-0009)
