- Official Statement from Apache (07/02/2008)
-
Fixed in Apache HTTP Server 2.2.9. http://httpd.apache.org/security/vulnerabilities_22.html
- Official Statement from Mandriva (03/12/2008)
-
Mandriva ships mod_proxy_balancer but will not be issuing updates to correct this flaw as the security risk is quite low due to the fact that is not enabled by default, the at-risk user would have to be authenticated, and successful exploitation would be limited to a denial of service on the web server.
- Official Statement from Red Hat (01/24/2008)
-
mod_proxy_balancer is shipped in Red Hat Enterprise Linux 5 and Red Hat Application Stack v2. We do not plan on correcting this issue as it poses a very low security risk: The balancer manager is not enabled by default, the user targeted by the CSRF would need to be authenticated, and the consequences of an exploit would be limited to a web server denial of service.
