Produttori e prodotti

CPE, acronimo di Common Platform Enumeration, è uno schema standardizzato per nominare hardware, software e sistemi operativi. CPE fornisce uno schema di denominazione strutturato per identificare e classificare in modo univoco sistemi, piattaforme e pacchetti informatici in base ad attributi quali produttore, nome del prodotto, versione, aggiornamento, edizione e lingua.

Nome: Creation of Immutable Text Using String Concatenation

The product creates an immutable text string using string concatenation operations.

Conseguenze comuni

Ambito	Impatto	Probabilità
Other	Reduce Performance Nota: When building a string via a looping feature (e.g., a FOR or WHILE loop), the use of += to append to the existing string will result in the creation of a new object with each iteration, which can be inefficient in comparison with use of text buffer data elements. This issue can make the product perform more slowly. If the relevant code is reachable by an attacker, then this could be influenced to create performance problems.

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.)
Effectiveness : High

Note sulla mappatura delle vulnerabilità

Giustificazione : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Commento : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
