By Vendor

By Weakness

#1

Out-of-bounds Write

The software writes data past the end, or before the beginning, of the intended buffer.

144

11.8%

#2

XSS

The software does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.

129

10.5%

#3

Improper Privilege Management

The software does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

5.6%

#4

Improper Input Validation

The product does not validate or incorrectly validates input that can affect the control flow or data flow of a program.

2.9%

#5

Marshaling, Unmarshaling

The application deserializes untrusted data without sufficiently verifying that the resulting data will be valid.

2.4%

#6

Dangling pointer

Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code.

2.0%

#7

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

The software constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component.

2.0%

#8

Directory traversal

The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

1.8%

#9

Information Leak

An information exposure is the intentional or unintentional disclosure of information to an actor that is not explicitly authorized to have access to that information.

1.6%

#10

AuthZ

The software performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions.

1.6%

#11

Improper Neutralization of Special Elements used in a Command ('Command Injection')

The software constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

1.5%

#12

Memory Corruption

The software performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer.

1.4%

#13

Out-of-bounds Read

The software reads data past the end, or before the beginning, of the intended buffer.

1.3%

#14

Uncontrolled Resource Consumption ('Resource Exhaustion')

The software does not properly restrict the size or amount of resources that are requested or influenced by an actor, which can be used to consume more resources than intended.

1.1%

#15

Shell injection

The software constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.

1.1%

#16

Cleartext Storage of Sensitive Information

The application stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

1.0%

#17

Insufficiently Protected Credentials

This weakness occurs when the application transmits or stores authentication credentials and uses an insecure method that is susceptible to unauthorized interception and/or retrieval.

1.0%

#18

Downstream Injection

The software constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

0.9%

#19

NULL Pointer Dereference

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.

0.8%

#20

AuthZ

The software does not perform an authorization check when an actor attempts to access a resource or perform an action.

0.8%

#21

Unrestricted File Upload

The software allows the attacker to upload or transfer files of dangerous types that can be automatically processed within the product's environment.

0.7%

#22

Incorrect Permission Assignment for Critical Resource

The software specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.

0.7%

#23

DLL preloading

The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors.

0.7%

#24

Race Condition

The program contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently.

0.6%

#25

Information Exposure Through an Error Message

The software generates an error message that includes sensitive information about its environment, users, or associated data.
