Description

In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a "Session" header. This comes from the "HTTP_SESSION" variable name used by mod_session to forward its data to CGIs, since the prefix "HTTP_" is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications.

• apache http server (>= 2.4.0 <= 2.4.29) • debian debian linux 8.0 • debian debian linux 9.0 • canonical ubuntu linux 14.04 • canonical ubuntu linux 16.04 • canonical ubuntu linux 17.10 • canonical ubuntu linux 18.04 • netapp santricity cloud connector • netapp storage automation store • netapp storagegrid • netapp clustered data ontap • redhat enterprise linux 6.0 • redhat enterprise linux 7.0 • redhat enterprise linux 7.4 • redhat enterprise linux 7.5 • redhat enterprise linux 7.6
