TITLE:
Websense Email Security / Personal Email Manager Multiple
Vulnerabilities

SECUNIA ADVISORY ID:
SA37091

VERIFY ADVISORY:
http://secunia.com/advisories/37091/

DESCRIPTION:
Nikolas Sotiriu has reported some vulnerabilities in Websense Email
Security and Personal Email Manager, which can be exploited by
malicious people to cause a DoS (Denial of Service) and conduct
cross-site scripting and script insertion attacks.

1) An error within the handling of HTTP requests within the Web
Administrator frontend (STEMWADM.EXE) can be exploited to crash the
service by sending HTTP GET requests to the port 8181 and then
closing the socket.

Note: By default, the service is restarted.

2) Input passed to the "FileName", "IsolatedMessageID", "ServerName",
"Dictionary", "Scoring", and "MessagePart" parameters in
web/msgList/viewmsg/actions/msgAnalyse.asp, to the "Queue",
"FileName", "IsolatedMessageID", and "ServerName" parameters in
web/msgList/viewmsg/actions/msgForwardToRiskFilter.asp and
web/msgList/viewmsg/viewHeaders.asp 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 the email subject is not properly sanitised
before being displayed. This can be exploited to execute arbitrary
HTML and script code in a user's browser session in context of an
affected site when a specially crafted email is shown in the Web
Administrator frontend.

The vulnerabilities are reported in Websense Email Security version
7.1 and Personal Email Manager version 7.1. Other versions may also
be affected.

SOLUTION:
Apply Hotfix 4 for Websense Email Security v7.1 and Personal Email
Manager v7.1.
