Description

SOAP Action Spoofing is a vulnerability that occurs when an attacker forges the SOAPAction header in a SOAP (Simple Object Access Protocol) message. SOAP messages are used for exchanging structured information in web services. If the SOAPAction header is not properly validated, an attacker can manipulate it to redirect the message to unintended endpoints or invoke unauthorized operations on the web service. This can lead to unauthorized access, data leakage, or manipulation of service functionality, potentially compromising the security and integrity of the web service.

Recommendation

To mitigate this vulnerability, ensure that only required SOAP operations are permitted and implement input validation to prevent unexpected SOAP actions. If necessary, validate the SOAPAction attribute against expected values before processing.
