Description

Hanno Boeck reports :

When configuring a web application to use only ssl (e.g. by forwarding all http-requests to https), a user would expect that sniffing and hijacking the session is impossible.

Though, for this to be secure, one needs to set the session cookie to have the secure flag. Otherwise the cookie will be transferred through HTTP if the victim's browser does a single HTTP request on the same domain.

Squirrelmail does not set that flag. It is fixed in the 1.5 test versions, but current 1.4.15 is vulnerable.
