The update of apache2 released as DLA-1900-1 contained an incomplete fix for CVE-2019-10092, a limited cross-site scripting issue affecting the mod_proxy error page. The old patch rather introduced a new CSRF protection which also caused a regression, an inability to dynamically change the status of members in the balancer via the balancer-manager.
This update reverts the change and provides the correct upstream patch to address CVE-2019-10092.
For Debian 8 ‘Jessie’, this problem has been fixed in version 2.4.10-10+deb8u16.
We recommend that you upgrade your apache2 packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
