Courier is an integrated mail and groupware server based on open protocols.
|
|
It provides ESMTP, IMAP, POP3, webmail, and mailing list services within a
|
|
single framework. The webmail functionality included in Courier called
|
|
SqWebMail allows you to access mailboxes from a web browser.

|
|
Luca Legato found that SqWebMail is vulnerable to a cross-site scripting
|
|
(XSS) attack. An XSS attack allows an attacker to insert malicious code
|
|
into a web-based application. SqWebMail doesn't filter appropriately data
|
|
coming from message headers before displaying them.
|
|

<impact type="normal">
|
|
<p>
|
|
By sending a carefully crafted message, an attacker can inject and execute
|
|
script code in the victim's browser window. This allows to modify the
|
|
behaviour of the SqWebMail application, and/or leak session information
|
|
such as cookies to the attacker.
|
|

|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time. All users are encouraged to
|
|
upgrade to the latest available version of Courier.

|

All Courier users should upgrade to the latest version:
