Server Status
Apache server-status is an Apache monitoring instance Available by default at http://$target/server-status
In normal cases, the server-status instance is not accessible by non-local IPs. However, due to misconfiguration, it can be publicly accessible. This leads anyone to view the great amount of data by server-status.
Data exposed
All URL requested by all hosts/vhosts, including obscure files/directories and session tokens
All requested client's IPs
Exploiting it
CVE-2021-41773
A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49-2.4.50.
An attacker could use a path traversal attack to map URLs to files outside the expected document root. If files outside of the document root are not protected by "require all denied" these requests can succeed. Additionally this flaw could leak the source of interpreted files like CGI scripts.
This issue only affects Apache 2.4.49 & 2.4.50 and not earlier versions.
