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.
eGroupWare 1.0.6 and earlier, when an e-mail is composed with an attachment but not sent, will send that attachment in the next e-mail, which may cause sensitive information to be sent to the wrong recipient.
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.
Multiple SQL injection vulnerabilities in index.php in eGroupware before 1.0.0.007 allow remote attackers to execute arbitrary SQL commands via the (1) filter or (2) cats_app parameter.
