Описание
The Business Connector has not been using the HTTP attributes introduced in recent years for guarding its session ID cookie against potential XSS attacks on a client side browser.
It can be used to permanently modify displayed content from a web site, allowing the malicious user to embed content that is rendered automatically, without the need to individually target victims.
Stored cross site scripting can also be used to steal another user#s authentication information such as data relating to their current session.
An attacker who gains access to this data may use this to impersonate the user and access all information with the same rights as the target user. In case of an administrator being impersonated, a full compromise of the application#s security can be may occur.
These attributes are: "HttpOnly" for disallowing read access to a cookie within JavaScript, and "Secure" for instructing a client that using such a cookie is only allowed via encrypted connections, i.e. HTTPS.
You're using a Businsess Connector 4.7 up to version CoreFix 9 or 4.8 up to CoreFix 2.

Как исправить
The HttpOnly attribute is now sent with the session ID cookie. Moreover, the Secure cookie can be turned on by setting the server.cnf variable watt.net.cookies.useSecure to true.
Business Connector 4.7: Please apply CoreFix 10.
Business Connector 4.8: Please apply at least CoreFix 3.
NB: if this note is applied to a Reverse Invoke configuration, please install the Core Fixes mentioned here on all involved Business Connector servers. Further ensure that both, the internal and the external, Business Connector servers are of the same release (i.e. a combination of 4.7 and 4.8 will no longer work).
