CWE-31 路径遍历：’dir....filename’ 类漏洞列表 3

CWE-31 路径遍历：’dir....filename’ 类弱点 3 条 CVE 漏洞汇总，含 AI 中文分析。

MITRE CWE 官方描述
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize 'dir\..\..\filename' (multiple internal backslash dot dot) sequences that can resolve to a location that is outside of that directory. This allows attackers to traverse the file system to access files or directories that are outside of the restricted directory. The 'dir\..\..\filename' manipulation is useful for bypassing some path traversal protection schemes. Sometimes a program only removes one "..\" sequence, so multiple "..\" can bypass that check. Alternately, this manipulation could be used to bypass a check for "..\" at the beginning of the pathname, moving up more than one directory level.

Implementation Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does. When performing input validation, consider all potentially relevant properties, including length, type of input, the full range…
Implementation Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
