Estado: ModificadaMedia (4.3)—

Multiple cross-site scripting (XSS) vulnerabilities in Movable Type (MT) before 3.34 allow remote attackers to inject arbitrary web script or HTML via comments that have (1) a malformed SGML numeric character reference with a '\0' (0x00) character in a javascript: URI or (2) an attribute in an element that lacks the '>' character at the end of the start tag, a different vulnerability than CVE-2007-0231.
