Nome: Least Privilege Violation

The elevated privilege level required to perform operations such as chroot() should be dropped immediately after the operation is performed.

Informações Gerais

Modos de Introdução

Implementation : REALIZATION: This weakness is caused during implementation of an architectural security tactic.
Operation

Plataformas Aplicáveis

Linguagem

Class: Not Language-Specific (Undetermined)

Consequências Comuns

Escopo Impacto Probabilidade
Access Control
Confidentiality		Gain Privileges or Assume Identity, Read Application Data, Read Files or Directories

Note: An attacker may be able to access resources with the elevated privilege that could not be accessed with the attacker's original privileges. This is particularly likely in conjunction with another flaw, such as a buffer overflow.

Mitigações Potenciais

Phases : Architecture and Design // Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Phases : Architecture and Design
Follow the principle of least privilege when assigning access rights to entities in a software system.

Notas de Mapeamento de Vulnerabilidade

Justificativa : 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.
Comentário : 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.

Padrões de Ataque Relacionados

CAPEC-ID Nome do Padrão de Ataque
CAPEC-17 Using Malicious Files
An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
CAPEC-35 Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
CAPEC-76 Manipulating Web Input to File System Calls
An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

Notas

CWE-271, CWE-272, and CWE-250 are all closely related and possibly overlapping. CWE-271 is probably better suited as a category.
