CWE-688: Function Call With Incorrect Variable or Reference as Argument
Presentation Filter:
 DescriptionThe software calls a function, procedure, or routine, but the caller specifies the wrong variable or reference as one of the arguments, which may lead to undefined behavior and resultant weaknesses. RelationshipsThe 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)
Modes Of IntroductionThe 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.
Applicable PlatformsThe 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. Languages C (Undetermined Prevalence) Perl (Undetermined Prevalence) Common ConsequencesThe 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.
Demonstrative ExamplesExample 1 In the following Java snippet, the accessGranted() method is accidentally called with the static ADMIN_ROLES array rather than the user roles. (bad code) Example Language: Java private static final String[] ADMIN_ROLES = ...;
public boolean void accessGranted(String resource, String user) { String[] userRoles = getUserRoles(user); }return accessGranted(resource, ADMIN_ROLES); private boolean void accessGranted(String resource, String[] userRoles) { // grant or deny access based on user roles ... Observed Examples
