Improper input validation cwe 1179: SEI CERT Perl Coding Standard - Guidelines 01. , improper type checking of uploaded files. 12, 8. Path Traversal. The product does not validate or incorrectly validates input that can affect the control flow or data flow of a program. Improper input validation [1] or unchecked user input is a type of vulnerability in computer software that may be used for security exploits. Back to top. Input validation is a frequently-used technique for checking potentially dangerous inputs in order to ensure that the inputs are safe for processing within the code, or when communicating with other components. Unchecked input is the root cause of some of today’s worst and most common software security problems. x CVSS Version 2. Also note that other kinds of weaknesses besides improper validation are included as members of this category. One of the key aspects of input handling is validating that the input satisfies a certain criteria. Memory Corruption - Generic. Unrestricted Upload of File With the relative decline of class-level weaknesses, more specific CWEs have moved up to take the place of these high-level classes, such as CWE-78 (Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')), CWE-22 (Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')), CWE-434 (Unrestricted Upload of File Show examples for CWE-20: Improper Input Validation . Common Weakness Assume all input is malicious. When software fails to properly validate input, an attacker can construct it in a way that the rest of the application does not expect. Improper Input Validation: CanFollow: Base - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention.

Learn More Improper input validation is a security vulnerability that occurs when an application does not properly validate or sanitize input data before processing it. It involves the process of ensuring that the input provided by users or external systems meets the predefined criteria before processing. Graphs of trends in Top 25 rankings are presented. 被利用可能性: High 基本描述. A community-developed list of SW & HW weaknesses that can become vulnerabilities. Specifically, the username value is used in a SQL query without any checks to ensure that it contains only expected values. Such errors could be used to bypass whitelist schemes by introducing dangerous inputs after they have been checked. Improper Input Validation. Leading the effort with support from the U.

For proper validation, it is important to identify the form and type of data that is acceptable and expected by the application. Note that "input validation" has very different meanings to different people, or within different classification schemes. S. Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') 9. CWE-74 Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-75 Failure to Sanitize Special Elements into a Different Plane (Special Element Injection) CWE-77 Improper Neutralization of Special Elements used in a Command ('Command Injection') Input validation can be used to detect unauthorized input before it is processed by the application. Common Weakness Enumeration (CWE) is a list of software weaknesses. , use a list of acceptable inputs that strictly conform to specifications. This vulnerability is the root cause of more than half of the top ten vulnerabilities in the CWE Top 25 list [3] and is present when a software system does not ensure that the received input can be processed safely and correctly. This issue affects Apache Traffic Server 7. CWE-78. The product/program does not validate or validate poorly or input that can disrupt a program's control flow or data flow. Content History. 结构: Simple. mitre. Reject any input that does not strictly conform to specifications, or transform it into something that does. Previously known as Broken Authentication, this category slid down from the second position and now includes Common Weakness Enumerations (CWEs) related to identification failures. Improper Input Validation: ParentOf: Variant - a weakness that is linked to a certain type of product, typically involving a specific language or technology. This will lead to parts of the system receiving unintended input, cwe 是社区开发的具有安全影响的常见软件和硬件漏洞类型列表。“弱点”是软件或硬件实现、代码、设计或架构中的缺陷、故障、错误或其他错误，如果不加以解决，可能会导致系统、网络或硬件容易受到攻击。针对开发和安全从业者社区，cwe 的主要目标是通过教育软件和硬件架构师、设计师 CWE-20 Improper Input Validation. Technology-Specific Input Validation Problems (CWE ID 100) - Class Constructor. Omitting validation for even a single input field may allow attackers the leeway they need.
