(Courier: XSS vulnerability in SqWebMail)
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.
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.
There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of Courier.
