Description
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.
Some well known impacts of the Digital Signature Spoofing Vulnerability are:
- Arbitrary requests can be sent and accepted by the server, completely bypassing the signature security mechanism in place.
- Attacker can modify some critical information.
- In some cases attacker can get some information from the spoofing signer
