Multiple cross-site scripting (XSS) vulnerabilities in Horde Kronolith Calendar Application H4 before 3.0.17, as used in Horde Groupware Webmail Edition before 4.0.8, allow remote attackers to inject arbitrary web script or HTML via the (1) tasks view or (2) search view.
A cross-site scripting (XSS) flaw was found in the way Kronolith, the Horde calendar application, sanitized content of certain event location parameters passed to month, monthlist and prevmonthlist application fields. A remote attacker could provide a specially-crafted URL that, when visited would lead to arbitrary HTML or webscript execution.
