Description

A static code block creates an instance of a class.

Extended description

This pattern identifies situations where a storable data element or member data element is initialized with a value in a block of code which is declared as static.

Common consequences

• Other: Reduce Performance — This issue can make the product perform more slowly by performing initialization before it is needed. If the relevant code is reachable by an attacker, then this performance problem might introduce a vulnerability.

Detection methods

• Automated Static Analysis: Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
