Improper Session Management in ABAP Server of SAP NetWeaver and ABAP Platform, SAP security note 2748063

Description

Under some circumstances, leverage of another user’s privileges is possible, because the ABAP Server of SAP NetWeaver and ABAP Platform does not delete the HTTP Security Session cookie from the browser, despite the HTTP Security Session being invalidated.

Access to this session cookie via local browser may allow the attacker to leverage the privileges of another user. The level of privileges attained depends upon the user whose session cookies are accessed.
