Categories

This category represents one of the phyla in the Seven Pernicious Kingdoms vulnerability classification. It includes weaknesses that occur when an application does not properly handle errors that occur during processing. According to the authors of the Seven Pernicious Kingdoms, "Errors and error handling represent a class of API. Errors related to error handling are so common that they deserve a special kingdom of their own. As with 'API Abuse,' there are two ways to introduce an error-related security vulnerability: the most common one is handling errors poorly (or not at all). The second is producing errors that either give out too much information (to possible attackers) or are difficult to handle."

Weaknesses in this category are related to errors in the management of cryptographic keys.

The software uses CRLF (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes CRLF sequences from inputs.

The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product.

The software uses a Pseudo-Random Number Generator (PRNG) that does not correctly manage seeds.

The application uses external input with reflection to select which classes or code to use, but it does not sufficiently prevent the input from selecting improper classes or code.

The software attempts to drop privileges but does not check or incorrectly checks to see if the drop succeeded.

The software does not properly account for differences in case sensitivity when accessing or determining the properties of a resource, leading to inconsistent results.

The software does not implement or incorrectly implements one or more security-relevant checks as specified by the design of a standardized algorithm, protocol, or technique.

Weaknesses in this category are typically introduced during code development, including specification, design, and implementation.
