Multiple unspecified vulnerabilities in Horde Groupware Webmail before Edition 1.1.1 (final) have unknown impact and attack vectors related to "unescaped output," possibly cross-site scripting (XSS), in the (1) object browser and (2) contact view.

Cross-site scripting (XSS) vulnerability in addevent.php in Horde Kronolith 2.1.7, Groupware Webmail Edition 1.0.6, and Groupware 1.0.5 allows remote attackers to inject arbitrary web script or HTML via the url parameter.

The _bad_protocol_once function in phpgwapi/inc/class.kses.inc.php in KSES, as used in eGroupWare before 1.4.003, Moodle before 1.8.5, and other products, allows remote attackers to bypass HTML filtering and conduct cross-site scripting (XSS) attacks via a string containing crafted URL protocols.

lib/Driver/sql.php in Turba 2 (turba2) Contact Manager H3 2.1.x before 2.1.7 and 2.2.x before 2.2-RC3, as used in products such as Horde Groupware before 1.0.4 and Horde Groupware Webmail Edition before 1.0.5, does not properly check access rights, which allows remote authenticated users to modify address data via a modified object_id parameter to edit.php, as demonstrated by modifying a personal address book entry when there is write access to a shared address book.

IMP Webmail Client 4.1.5, Horde Application Framework 3.1.5, and Horde Groupware Webmail Edition 1.0.3 does not validate unspecified HTTP requests, which allows remote attackers to (1) delete arbitrary e-mail messages via a modified numeric ID or (2) "purge" deleted emails via a crafted email message.

Multiple cross-site scripting (XSS) vulnerabilities in Horde Groupware Webmail 1.0 allow remote authenticated users to inject arbitrary web script or HTML via unspecified vectors in (1) imp/search.php and (2) ingo/rule.php. NOTE: this issue has been disputed by the vendor, noting that the search.php issue was resolved in CVE-2006-4255, and attackers can only use rule.php to inject XSS into their own pages

Unspecified vulnerability in the calendar component in Horde Groupware Webmail Edition before 1.0, and Groupware before 1.0, allows remote attackers to include certain files via unspecified vectors. NOTE: some of these details are obtained from third party information.

Cross-site scripting (XSS) vulnerability in index.php in Enterprise Groupware System (EGS) 1.2.4 and earlier allows remote attackers to inject arbitrary web script or HTML via the module parameter.

Multiple cross-site scripting (XSS) vulnerabilities in eGroupware before 1.0.0.007 allow remote attackers to inject arbitrary web script or HTML via the (1) ab_id, (2) page, (3) type, or (4) lang parameter to index.php or (5) category_id parameter.
