CWE - Common Weakness Enumeration


Do you have any inquiries concerning CWE? We make sense of what CWE (Common Weakness Enumeration) is and why it is so significant in online protection.

What is Common Weakness Enumeration?

CWE (Common Weakness Enumeration) is a product security imperfection grouping plan that distinguishes execution blunders that can prompt weaknesses. It's a local area drive pointed toward distinguishing and alleviating code blemishes and weaknesses, as well as creating devices to support their avoidance.

The National Cyber Security Division and US-CERT help mitre cwe. CWE sorts blemishes and imperfections into north of 600 classifications.

CWE endeavors to kill imperfections and issues in programming by showing designers how to augment, less weak items. WAF and API security engineers can use CWE to forestall weaknesses in their code as it is being created. Take off (Security Orchestration, Automation, and Response) frameworks influence CWEs to robotize remediation rules and cycles.

CWEs are all around reported arrangements of weaknesses that incorporate careful clarifications, models, related Common Vulnerabilities and Exposures (CVEs), and associations with different weaknesses. CWE-200, for instance, contains various reproduced situations along with a rundown of CVEs that exploit the weakness.

CWE records can be utilized by security experts to make proactive cautions and remediation from connected assault designs. Each CWE has a part that rundowns different assault designs and the weaknesses that go with them. Associations can utilize this data to make explicit location frameworks for CWEs in light of their gamble resilience.

For engineers and scientists, the CWE makes distinguishing normal weaknesses across dialects, equipment, spaces, and structural standards simpler.

CWE examples

The web application doesn't, or can't, adequately approve assuming that the client who presented the solicitation provided a very much shaped, genuine, predictable solicitation.

An aggressor might have the option to trick a client into sending an accidental solicitation to the web server that would be treated as a certified solicitation assuming a web server is arranged to get a solicitation from a client with practically no means for confirming that it was sent deliberately. This should be possible through a URL, picture load, XMLHttpRequest, and different techniques, and can bring about information exposure or accidental code execution.

  • CWE-787: Out-of-limits Write

The product composes information past the finish of the cradle, or before the beginning of the support.

This can prompt information debasement, an accident, or code execution. The product might change a list or execute pointer math on a memory address that is outside the cradle's limits. The outcome of an ensuing compose activity is vague or surprising.

  • CWE-78: Improper Neutralization of Special Elements utilized in an OS Command ('OS Command Injection')

Whenever an OS order is given to a downstream part, the product creates all or a piece of it utilizing remotely impacted input from an upstream part, however it doesn't kill or inappropriately kills specific components that could influence the planned OS guidance.

Accordingly, aggressors might have the option to utilize the working framework to execute surprising and possibly hazardous orders. This shortcoming could prompt a weakness in circumstances when the assailant doesn't have direct admittance to the working framework, like web applications. Assuming the issue is found in an advantaged program, it could permit an assailant to indicate guidelines that would ordinarily be inaccessible, or to call substitute orders with honors that the aggressor doesn't have. Since assailant controlled directions might run with specific framework honors, the issue is exacerbated in the event that the compromised interaction doesn't comply with the guideline of least honor, which builds how much harm.


CWEs contrast from CVEs in that they feature weaknesses instead of a particular event of one inside an item.

A CVE may, for instance, portray a weakness in a working framework that permits assailants to remotely execute code. This CVE section exclusively depicts a solitary item's weakness.

A CWE is a weakness that isn't attached to a specific item. CWE has turned into a standard jargon for tending to programming security imperfections' destruction or alleviation. Engineers can deliver items that are without weaknesses since they have early admittance to information in regards to flaws, keeping away from future security hardships. This empowers designers to keep awake with high speed improvement lifecycles, produce better items, appropriate them to purchasers quicker, lower assault surfaces, and stay away from more cyberattacks.

The following are a couple of occurrences of CWEs:

  • Beyond the field of play Write
  • Cross-site Scripting
  • Ill-advised Input Validation
  • Missing Authentication for Critical Function

Why is Common Weakness Enumeration important?

CWE alludes to a rundown of defects in programming engineering, plan, or code. Defects, bugs, issues, or different mistakes are instances of shortcomings that produce weaknesses that can be taken advantage of by both inside and outside powers. Programming execution, code, plan, and design all have imperfections.

In 2005, the CWE list was made as a local area based try to fill in as a typical gauge for recognizing programming imperfections in a basic way. Organizations can utilize quantifiable security innovations to distinguish, relieve, and forestall abuse of their PC frameworks, which are without a doubt the backbone of any 21st-century firm, when the imperfections have been recognized. As more organizations change to distributed computing, this turns out to be much more basic.

"CWE isn't yet essential for the Security Content Automation Protocol," as indicated by the NVD, in spite of the way that CWE is a typical norm for recognizing programming blemishes (SCAP). The CWE grouping instrument is utilized by NVD to recognize CVEs in light of the sort of weakness they address." Simply said, numerous administration and private-area associations depend on the CWE for "widespread" standard information, yet it isn't utilized on all rundowns and conventions.

The CWE list should utilize normalized language and ID to give predictable and solid information, very much like any ISO-type guidelines. CWE utilizes a similar method to make its information accessible to individuals everywhere. The CWE is available to everybody, from analysts to engineers to home PC specialists, and there are no limitations on who can utilize it.

CWE Top 25

The shortcomings in the CWE Top 25 for 2021 are displayed here, alongside their common weakness enumeration scoring system.

CWEs are all around reported arrangementsof weaknesses that incorporate careful clarifications, models, related CommonVulnerabilities and Exposures (CVEs), and associations with differentweaknesses. CWE-200, for instance, contains various reproduced situations alongwith a rundown of CVEs that exploit the weakness.

CWE records can be utilized by securityexperts to make proactive cautions and remediation from connected assaultdesigns. Each CWE has a part that rundowns different assault designs and the weaknessesthat go with them. Associations can utilize this data to make explicit locationframeworks for CWEs in light of their gamble resilience.

For engineers and scientists, the CWE makesdistinguishing normal weaknesses across dialects, equipment, spaces, andstructural standards simpler.
