Description

A flaw was found in open62541. An unauthenticated remote attacker can exploit a vulnerability in the GetEndpoints Discovery Service by sending a malformed request with an excessively long, unvalidated endpointUrl field. This can lead to the server buffering large amounts of data indefinitely, causing server memory exhaustion and a Denial of Service (DoS) condition. This attack can occur before a secure session is established and bypasses encryption configurations.
