4) Description of Vulnerability

Secunia Research has discovered two vulnerabilities in phpList, which 
can be exploited by malicious users and malicious people to conduct 
script insertion attacks.

1) Input passed via the "description" parameter when adding or editing 
a subscriber list description is not properly sanitised before being 
displayed to the user. This can be exploited to insert arbitrary HTML 
and script code, which will execute in a user's browser session in 
context of an affected site when the malicious data is being viewed.

Successful exploitation of this vulnerability requires permissions to 
manage lists.

2) Input passed via the "login" parameter to admin/index.php is not 
properly sanitised in admin/eventlog.php before being displayed to the 
user. This can be exploited to insert arbitrary HTML and script code, 
which will execute in a user's browser session in context of an 
affected site when the malicious data is being viewed.
