Bug#941202: apache2: Fix for CVE-2019-10092 results in AH10187 when hitting balancer-manager

Package: apache2
Version: 2.4.25-3+deb9u8
Severity: normal

Dear Maintainer,

The fix for CVE-2019-10092 results in the following error when attempting to access details of a member in a mod_proxy_balancer http balancer via the balancer-manager web page:

"[Thu Sep 26 09:51:08.228312 2019] [proxy_balancer:error] [pid 13106:tid 139942457935616] [client] AH10187: ignoring params in balancer-manager cross-site access, referer: http://httpbalancer01/httpbalancer/__balancer-manager?b=http-balancer&w="

The net effect of this is an inability to dynamically change the status of members in the balancer via the balancer-manager.

Raised in Apache httpd-2 bug report 63688: https://bz.apache.org/bugzilla/show_bug.cgi?id=63688

Committed upstream in r1865749: https://svn.apache.org/viewvc?view=revision&revision=1865749
