CWE-651: Exposure of WSDL File Containing Sensitive Information
The Web services architecture may require exposing a Web Service Definition Language (WSDL) file that contains information on the publicly accessible services and how callers of these services should interact with them (e.g. what parameters they expect and what types they return).
An information exposure may occur if any of the following apply:
The table(s) below shows the weaknesses and high level categories that are related to this weakness. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore.
Relevant to the view "Research Concepts" (CWE-1000)
The different Modes of Introduction provide information about how and when this weakness may be introduced. The Phase identifies a point in the life cycle at which introduction may occur, while the Note provides a typical scenario related to introduction during the given phase.
The listings below show possible areas for which the given weakness could appear. These may be for specific named Languages, Operating Systems, Architectures, Paradigms, Technologies, or a class of such platforms. The platform is listed along with how frequently the given weakness appears for that instance.
Class: Language-Independent (Undetermined Prevalence)
Web Server (Often Prevalent)
The table below specifies different individual consequences associated with the weakness. The Scope identifies the application security area that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in exploiting this weakness. The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. For example, there may be high likelihood that a weakness will be exploited to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact.
The WSDL for a service providing information on the best price of a certain item exposes the following method: float getBestPrice(String ItemID) An attacker might guess that there is a method setBestPrice (String ItemID, float Price) that is available and invoke that method to try and change the best price of a given item to their advantage. The attack may succeed if the attacker correctly guesses the name of the method, the method does not have proper access controls around it and the service itself has the functionality to update the best price of the item.
This MemberOf Relationships table shows additional CWE Categories and Views that reference this weakness as a member. This information is often useful in understanding where a weakness fits within the context of external information sources.
