이름: Windows Hard Link
The product, when opening a file or directory, does not sufficiently handle when the name is associated with a hard link to a target that is outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.

| Confidentiality Integrity | Read Files or Directories, Modify Files or Directories 참고: Failure for a system to check for hard links can result in vulnerability to different types of attacks. For example, an attacker can escalate their privileges if a file used by a privileged program is replaced with a hard link to a sensitive file (e.g. AUTOEXEC.BAT). When the process opens the file, the attacker can assume the privileges of that process, or prevent the program from accurately processing data. |

|---|---|
CVE-2002-0725 | Chain: File system allows local attackers to hide file usage activities via a hard link (CWE-65) to the target file, which causes the link to be recorded in the audit trail instead of the target file (CWE-221). |
CVE-2003-0844 | Web server plugin allows local users to overwrite arbitrary files via a symlink attack on predictable temporary filenames. |

근거 : 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.댓글 : 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.
