Leveranciers en producten

CPE, wat staat voor Common Platform Enumeration, is een gestandaardiseerd schema voor het benoemen van hardware, software en besturingssystemen. CPE biedt een gestructureerd naamgevingsschema om IT-systemen, platforms en pakketten uniek te identificeren en te classificeren op basis van bepaalde attributen zoals leverancier, productnaam, versie, update, editie en taal.

Naam: Use of Blocking Code in Single-threaded, Non-blocking Context

The product uses a non-blocking model that relies on a single threaded process for features such as scalability, but it contains code that can block when it is invoked.

Veelvoorkomende gevolgen

Bereik	Impact	Waarschijnlijkheid
Availability	DoS: Resource Consumption (CPU) Opmerking: When an attacker can directly invoke the blocking code, or the blocking code can be affected by environmental conditions that can be influenced by an attacker, then this can lead to a denial of service by causing unexpected hang or freeze of the code. An unexpected call to blocking code can trigger an infinite loop, or a large loop that causes the software to pause and wait indefinitely.

Mogelijke risicobeperkingen

Phases : Implementation
Generally speaking, blocking calls should be replaced with non-blocking alternatives that can be used asynchronously. Expensive computations should be passed off to worker threads, although the correct approach depends on the framework being used.
Phases : Implementation
For expensive computations, consider breaking them up into multiple smaller computations. Refer to the documentation of the framework being used for guidance.

Notities kwetsbaarheidsmapping

Rechtvaardiging : 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.
Opmerking : 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.

Gerelateerde aanvalspatronen

CAPEC ID	Naam aanvalspatroon
CAPEC-25	Forced Deadlock The adversary triggers and exploits a deadlock condition in the target software to cause a denial of service. A deadlock can occur when two or more competing actions are waiting for each other to finish, and thus neither ever does. Deadlock conditions can be difficult to detect.
