| Bereik | Impact | Waarschijnlijkheid |
|---|---|---|
| Confidentiality Integrity | Read Files or Directories, Modify Files or Directories Opmerking: 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. |
Detectiemethoden
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.)Effectiviteit : High
Notities kwetsbaarheidsmapping
Rechtvaardiging : 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.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.
