Undertow in Red Hat wildfly before version 11.0.0.Beta1 is vulnerable to a resource exhaustion resulting in a denial of service. Undertow keeps a cache of seen HTTP headers in persistent connections. It was found that this cache can easily exploited to fill memory with garbage, up to “max-headers” (default 200) * “max-header-size” (default 1MB) per active TCP connection.
Affected configurations
| CPE | Name | Operator | Version |
|---|---|---|---|
| org.wildfly:wildfly-undertow | lt | 11.0.0.Beta1 |
