SAP NetWeaver Process Integration (Adapter Engine), fixed in versions 7.10 to 7.11, 7.30, 7.31, 7.40, 7.50; is vulnerable to Digital Signature Spoofing. It is possible to spoof XML signatures and send arbitrary requests to the server via PI Axis adapter. These requests will be accepted by the PI Axis adapter even if the payload has been altered, especially when the signed element is the body of the xml document.
Weakness
This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.
