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.

Security readout for executives and security teams

Movable Type versions before 3.34 could let an attacker place script or HTML through comments. If viewed by an administrator or visitor, that script could run in their browser. The sources do not provide CVSS, KEV listing, or current exploitation evidence. Exposure is most likely on legacy Movable Type installations older than 3.34 that still accept or display untrusted comments. The source bundle does not provide CPEs, deployment prevalence, or supported product details. Treat this as a legacy web-application risk. Prioritize if Movable Type is internet-facing, accepts comments, or is administered by privileged users. Urgency is lower where no affected installation exists. Mitigation focus: Inventory Movable Type instances and confirm whether any are older than 3.34.; Upgrade affected Movable Type installations to 3.34 or a supported later release.; Check Six Apart or current vendor guidance before production changes..
