Title
Undertow: undertow: denial of service due to premature multipart/form-data parsing in get requests
Summary
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).
Severity ?
5.9 (Medium)
CWE
- CWE-770 - Allocation of Resources Without Limits or Throttling
