It was found that the fix for CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration β€œrequire all denied”, these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution (CVE-2021-42013).
