Description
The Undertow web server enforces a default maximum HTTP request entity size limit. Any request (including GET or HEAD) containing a body that exceeds this configurable limit is safely dropped by the server, preventing single-request Resource Exhaustion (Out of Memory) Denial of Service attacks.

Type Values Removed Values Added
Description A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending an HTTP GET request containing multipart/form-data content. If the underlying application processes parameters using methods like `getParameterMap()`, the server prematurely parses and stores this content to disk. This could lead to resource exhaustion, potentially resulting in a Denial of Service (DoS). The Undertow web server enforces a default maximum HTTP request entity size limit. Any request (including GET or HEAD) containing a body that exceeds this configurable limit is safely dropped by the server, preventing single-request Resource Exhaustion (Out of Memory) Denial of Service attacks.
