CWE-392: Missing Report of Error Condition

Weakness ID: 392
Abstraction: Base
Structure: Simple
Status: Draft
Presentation Filter:
+ Description
The software encounters an error but does not provide a status code or return value to indicate that an error has occurred.
+ Relationships

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.

+ Modes Of Introduction

The different Modes of Introduction provide information about how and when this weakness may be introduced. The Phase identifies a point in the software life cycle at which introduction may occur, while the Note provides a typical scenario related to introduction during the given phase.

PhaseNote
Architecture and DesignOMISSION: This weakness is caused by missing a security tactic during the architecture and design phase.
Implementation
+ Applicable Platforms
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.

+ Common Consequences

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.

Technical Impact: Varies by Context; Unexpected State

Errors that are not properly reported could place the system in an unexpected state that could lead to unintended behaviors.
+ Demonstrative Examples

Example 1

In the following snippet from a doPost() servlet method, the server returns "200 OK" (default) even if an error occurs.

(bad)
Example Language: Java 
try {
// Something that may throw an exception.
...

} catch (Throwable t) {
logger.error("Caught: " + t.toString());
return;

}
+ Observed Examples
ReferenceDescription
Function returns "OK" even if another function returns a different status code than expected, leading to accepting an invalid PIN number.
Error checking routine in PKCS#11 library returns "OK" status even when invalid signature is detected, allowing spoofed messages.
Kernel function truncates long pathnames without generating an error, leading to operation on wrong directory.
Function returns non-error value when a particular erroneous condition is encountered, leading to resultant NULL dereference.
+ Weakness Ordinalities
OrdinalityDescription
Primary
(where the weakness exists independent of other weaknesses)
Resultant
(where the weakness is typically related to the presence of some other weaknesses)
+ Memberships
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.
