CWE-1127: Compilation with Insufficient Warnings or Errors
Weakness ID: 1127
Vulnerability Mapping:ALLOWEDThis CWE ID may be used to map to real-world vulnerabilities Abstraction:
ClassClass - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource.

Description
The code is compiled without sufficient warnings enabled.
Dimensions
The Dimensions table provides information about the
different dimensions associated with this weakness. The Type identifies the dimension type,
while the Value provides the specific value for that dimension.

Common Consequences
This table 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.
Impact
Details
Reduce Maintainability
Scope: Other
This issue makes it more difficult to maintain the product, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. It also might make it easier to introduce vulnerabilities.
Increase Analytical Complexity
Scope: Other
This issue may prevent the detection of subtle
bugs or quality issues.
Potential Mitigations
Phase(s)
Mitigation
Build and Compilation
Compile the code with the best options
available to generate the most warnings that are
actionable.
Note:
Compilers with maximum settings could generate too
many warnings that are not directly actionable to the
developer. The developer should also be careful to
know that some options might not actually generate all
possible warnings that the compiler can detect. For
example, in C, the GCC compiler's "-Wall" option does
not actually capture all possible warnings.
Relationships
This table 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, Overlaps, and CanAlsoBe are defined to show similar weaknesses that the user
may want to explore.

ChildOf
Pillar - a weakness that is the most abstract type of weakness and represents a theme for all class/base/variant weaknesses related to it. A Pillar is different from a Category as a Pillar is still technically a type of weakness that describes a mistake, while a Category represents a common characteristic used to group related things.
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.

Manual Analysis
Inspect scripts and tools that invoke the
compiler. Ensure that the appropriate command line
switches and/or configuration are specified to report
warnings and errors.

Reason
Acceptable-Use
Rationale
This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comments
Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
