{
"lang": "en",
"value": "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. This issue is known to be exploited in the wild. This issue only affects Apache 2.4.49 and not earlier versions. The fix in Apache HTTP Server 2.4.50 was found to be incomplete, see CVE-2021-42013."

Si los archivos fuera de estos directorios no est\u00e1n protegidos por la configuraci\u00f3n habitual por defecto \"require all denied\", estas peticiones pueden tener \u00e9xito. Si los scripts CGI tambi\u00e9n est\u00e1n habilitados para estas rutas alias, esto podr\u00eda permitir la ejecuci\u00f3n remota de c\u00f3digo.
