07 Oct 2021 — 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 "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue only affects Apache 2.4.49 and Apache ... • https://packetstorm.news/files/id/181114 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

05 Oct 2021 — A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. 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 "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution.

05 Oct 2021 — While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request processing, allowing an external source to DoS the server. This requires a specially crafted request. The vulnerability was recently introduced in version 2.4.49. No exploit is known to the project. Mientras se realizaba el fuzzing del httpd versión 2.4.49, se detectó una nueva desreferencia de puntero null durante el procesamiento de peticiones HTTP/2, permitiendo a una fuente externa hacer DoS al servidor. • http://www.openwall.com/lists/oss-security/2021/10/05/1 • CWE-476: NULL Pointer Dereference •
