Descripciones CAPEC

An adversary injects oversized serialized data payloads into a parser during data processing to produce adverse effects upon the parser such as exhausting system resources and arbitrary code execution.

Informaciones CAPEC

Flujo de ejecución

1) Explore

An adversary determines the input data stream that is being processed by an serialized data parser on the victim's side.

2) Experiment

An adversary crafts input data that may have an adverse effect on the operation of the data parser when the data is parsed on the victim's system.

Prerrequisitos

An application uses an parser for serialized data to perform transformation on user-controllable data.
An application does not perform sufficient validation to ensure that user-controllable data is safe for a data parser.

Habilidades requeridas

Denial of service
Arbitrary code execution

Mitigaciones

Carefully validate and sanitize all user-controllable serialized data prior to passing it to the parser routine. Ensure that the resultant data is safe to pass to the parser.
Perform validation on canonical data.
Pick a robust implementation of the serialized data parser.
Validate data against a valid schema or DTD prior to parsing.

Debilidades relacionadas

CWE-ID Nombre de la debilidad

CWE-112

Missing XML Validation
The product accepts XML from an untrusted source but does not validate the XML against the proper schema.

CWE-20

Improper Input Validation
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

CWE-674

Uncontrolled Recursion
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.

CWE-770

Allocation of Resources Without Limits or Throttling
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
