DESCRIPTION:
A weakness and multiple vulnerabilities have been reported in Kayako
SupportSuite, which can be exploited by malicious users to conduct
script insertion attacks and by malicious people to disclose
sensitive information, conduct cross-site scripting attacks, and
conduct script insertion attacks.

1) The weakness is caused due to the application displaying the full
installation path when the "_m" and "_a" parameters to
staff/index.php are set to empty values.

2) Input passed via the "resultdata" parameter to staff/index.php
(when "_m" is set to "news", "_a" is set to "managesubscribers", and
"importsub" is set to "1") is not properly sanitised before being
returned to the user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

3) Input passed via various parameters to multiple scripts is not
properly sanitised before being used. This can be exploited to insert
arbitrary HTML and script code, which will be executed in a user's
browser session in context of an affected site when the malicious
data is being viewed.

Examples:
http://[host]/staff/index.php?_m=news&_a=insertnews&subject=[script]
http://[host]/staff/index.php?_m=troubleshooter&_a=insertcategory&description=[script]
http://[host]/staff/index.php?_m=downloads&_a=insertfile&title=[script]
http://[host]/staff/index.php?_m=teamwork&_a=insertcontact&fullname=[script]&jobtitle=[script]&email1address=[script]&email2address=[script]&email3address=[script]&customerid=[script]&mobiletelephonenumber=[script]
http://[host]/staff/index.php?_m=livesupport&_a=insertcampaign&redirecturl=[script]
http://[host]/staff/index.php?_m=livesupport&_a=insertcannedresponse&title=[script]
http://[host]/staff/index.php?_m=tickets&_a=insertalert&title=[script]
http://[host]/staff/index.php?_m=tickets&_a=insertfilter&title=[script]

Successful exploitation of these vulnerabilities requires a staff
account.

4) Input passed via the "Subject" parameter to an unspecified script
in the LiveSupport module, the "Full Name" and "Subject" parameters
to an unspecified script in the Tickets module, and the "Full Name"
parameter to unspecified scripts in the News and Knowledgebase
modules is not properly sanitised before being used. This can be
exploited to insert arbitrary HTML and script code, which will be
executed in a user's browser session in context of an affected site
when the malicious data is being viewed.

The vulnerabilities are reported in version 3.70.02. Other versions
may also be affected.

SOLUTION:
Apply patches (please contact the vendor for more information).

PROVIDED AND/OR DISCOVERED BY:
