This issue affects the function TicketManager::addProject of the file main/inc/lib/TicketManager.php of the component Ticket Module. Executing a manipulation of the argument Name can lead to cross site scripting. The attack may be performed from remote. The exploit has been publicly disclosed and may be utilized. This patch is called 6dfa0f4de45afc1b27333304b4cd4532db478f74/dd3e4d32971efca4197eb2df97f69de25a786e3c/119773d45c31da53b44cbfdb3f4910bc983cc7b0/cb6fe2127e587603451c609b4ed78c0293fcc3fa. It is best practice to apply a patch to resolve this issue.","summary":"A flaw in the Chamilo LMS ticket module's TicketManager::addProject function does not sanitize the Name argument, so injected script can run in a user's browser.
