CVE-2022-22721

Si LimitXMLRequestBody está configurado para permitir cuerpos de petición de más de 350 MB (por defecto 1M) en sistemas de 32 bits, es producido un desbordamiento de enteros que causa posteriormente escrituras fuera de límites. Este problema afecta a Apache HTTP Server 2.4.52 y anteriores

A flaw was found in httpd, where it incorrectly limits the value of the LimitXMLRequestBody option. This issue can lead to an integer overflow and later causes an out-of-bounds write.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Apache HTTPD Server. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the ap_escape_html2 function. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the service account.
