The remote host is affected by the vulnerability described in GLSA-200408-02 (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.
Impact :
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 :
There is no known workaround at this time. All users are encouraged to upgrade to the latest available version of Courier.
