Posted February 21, 2012, in News.

Movable Type 5.13, 5.07, and 4.38 were released as mandatory security updates. These updates resolve multiple vulnerabilities discovered in Movable Type 5.x and Movable Type 4.x.

Impact

5.13, 5.07, and 4.38 address the multiple vulnerabilities including:

  • Session Hijack and CSRF exist in the commenting and the community script. A remote attacker could hijack the user session or could execute arbitrary script code on victim's browser under the certain circumstances.
  • XSS exists in templates where the variables are not escaped properly. A remote attacker could inject client-side script into web pages viewed by other users.
  • XSS exists in mt-wizard.cgi. This vulnerability was reported by Trustwave (TWSL2012-003)
