Description

Some vulnerabilities have been reported in various Horde products, which can be exploited by malicious people to conduct script insertion attacks.

1) Input via MIME attachment linking is not properly sanitised in the MIME library before being used. This can be exploited to execute arbitrary HTML and script code in a user's browser session if e.g. a malicious email is viewed.

This vulnerability is reported in versions prior to Horde Groupware Webmail Edition version 1.1.3, Horde Groupware version 1.1.3, and Horde Application Framework version 3.2.2.

2) Input containing the "/" character as replacement for a space character is not properly sanitised. This can be exploited to execute arbitrary HTML and script code in a user's browser session if e.g. a malicious HTML email is viewed.

Successful exploitation requires that the victim's browser handles "/" as space characters.

This vulnerability is reported in versions prior to Horde Groupware Webmail Edition version 1.0.8 and 1.1.3, Horde Groupware version 1.0.7 and 1.1.3, Horde Application Framework version 3.1.9 and 3.2.2.


Solution
Update to Horde Groupware Webmail Edition version 1.0.8 or 1.1.3, Horde Groupware version 1.0.7 or 1.1.3, Horde Application Framework version 3.1.9 or 3.2.2.
