Description Sam Fowler 2018-03-26 04:22:56 UTC
Apache HTTP Server (httpd) through version 2.4.29 has a vulnerability in the handling of HTTP session headers in mod_session. 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.

Comment 1 Sam Fowler 2018-03-26 04:23:14 UTC
Created httpd tracking bugs for this issue:

Affects: fedora-all [bug 1560396]

Comment 7 Riccardo Schirone 2018-04-12 14:26:50 UTC
Statement:

This issue did not affect the versions of httpd as shipped with Red Hat Enterprise Linux 5 and 6 as they did not include mod_session module.

Comment 8 Jason Shepherd 2018-05-25 05:00:46 UTC
mod_session is not installed in RHMAP HTTPD image. Marking RHMAP as not affected.
