Cross-site scripting (XSS) vulnerability in the Spike PHPCoverage (aka spikephpcoverage) library, as used in Moodle 2.0.x before 2.0.2 and other products, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
