Nama: Missing Release of File Descriptor or Handle after Effective Lifetime

Konsekuensi Umum

Cakupan Dampak Kemungkinan
AvailabilityDoS: Resource Consumption (Other)

Catatan: An attacker that can influence the allocation of resources that are not properly released could deplete the available resource pool and prevent all other processes from accessing the same type of resource. When a file descriptor or handle is not released after use (typically by explicitly closing it), attackers can attempt to open a large number of file descriptors/handles, thus consuming all available file descriptors/handles, or otherwise preventing other system processes from obtaining their own file descriptors/handles.

Metode Deteksi

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.)

Catatan Pemetaan Kerentanan

Justifikasi : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Komentar : 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.
