名前: Creation of chroot Jail Without Changing Working Directory

The product uses the chroot() system call to create a jail, but it does not change the working directory afterward.

一般情報

背景の詳細

導入モード

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

一般的な結果

スコープ 影響 可能性
Confidentiality
Integrity
Read Files or Directories, Modify Files or Directories

注記:If the working directory is not changed after the chroot() call, relative paths may still refer to file system resources outside of the jail. Attackers may be able to read or write to files outside of the jail.

検出方法

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.)
有効性 : High

脆弱性マッピングノート

理由 : 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.
コメント : 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.
