horde: XSS vulnerability via data: URIs

Text_Filter/lib/Horde/Text/Filter/Xss.php in Horde Application Framework before 3.3.6, Horde Groupware before 1.2.5, and Horde Groupware Webmail Edition before 1.2.5 does not properly handle data: URIs, which allows remote attackers to conduct cross-site scripting (XSS) attacks via data:text/html values for the HREF attribute of an A element in an HTML e-mail message. NOTE: the vendor states that the issue is caused by "an XSS vulnerability in Firefox browsers."

Cross-site scripting (XSS) vulnerability in the XSS filter (framework/Text_Filter/Filter/xss.php) in Horde Application Framework 3.2.2 and 3.3, when Internet Explorer is being used, allows remote attackers to inject arbitrary web script or HTML via unknown vectors related to style attributes.

Horde: Improper validation of image form fields (local files overwrite)

The form library in Horde Application Framework 3.2 before 3.2.5 and 3.3 before 3.3.5; Groupware 1.1 before 1.1.6 and 1.2 before 1.2.4; and Groupware Webmail Edition 1.1 before 1.1.6 and 1.2 before 1.2.4; reuses temporary filenames during the upload process which allows remote attackers, with privileges to write to the address book, to overwrite arbitrary files and execute PHP code via crafted Horde_Form_Type_image form field elements.

horde: PHP_SELF XSS vulnerabilities

Multiple cross-site scripting (XSS) vulnerabilities in the administration interface in Horde Application Framework before 3.3.6, Horde Groupware before 1.2.5, and Horde Groupware Webmail Edition before 1.2.5 allow remote attackers to inject arbitrary web script or HTML via the PATH_INFO to (1) phpshell.php, (2) cmdshell.php, or (3) sqlshell.php in admin/, related to the PHP_SELF variable.

Cross-site scripting (XSS) vulnerability in the "help window" (help.php) in Horde Application Framework 2.2.6 allows remote attackers to inject arbitrary web script or HTML via the (1) module, (2) topic, or (3) module parameters.

Cross-site scripting (XSS) vulnerability in Horde 3.0.4 before 3.0.4-RC2 allows remote attackers to inject arbitrary web script or HTML via the parent frame title.

Eval injection vulnerability in Horde Application Framework versions 3.0 before 3.0.10 and 3.1 before 3.1.1 allows remote attackers to execute arbitrary code via the help viewer.

index.php in Horde Application Framework before 3.1.2 allows remote attackers to include web pages from other sites, which could be useful for phishing attacks, via a URL in the url parameter, aka "cross-site referencing." NOTE: some sources have referred to this issue as XSS, but it is different than classic XSS.
