CAPEC 218

Spoofing of UDDI/ebXML Messages

Attack Pattern ID: 218 (Detailed Attack Pattern Completeness: Stub)

Typical Severity: Medium

Status: Draft

Description

Summary

An attacker spoofs a UDDI, ebXML, or similar message in order to impersonate a service provider in an e-business transaction. UDDI, ebXML, and similar standards are used to identify businesses in e-business transactions. Among other things, they identify a particular participant, WSDL information for SOAP transactions, and supported communication protocols, including security protocols. By spoofing one of these messages an attacker could impersonate a legitimate business in a transaction or could manipulate the protocols used between a client and business. This could result in disclosure of sensitive information, loss of message integrity, or even financial fraud.

Attack Prerequisites

The targeted business's UDDI or ebXML information must be served from a location that the attacker can spoof or compromise or the attacker must be able to intercept and modify unsecured UDDI/ebXML messages in transit.

Resources Required

The attacker must be able to force the target user to accept their spoofed UDDI or ebXML message as opposed to the a message associated with a legitimate company. Depending on the follow-on for the attack, the attacker may also need to serve its own web services.

Solutions and Mitigations

Implementation: Clients should only trust UDDI, ebXML, or similar messages that are verifiably signed by a trusted party.
