CWE-23 相对路径遍历 类漏洞列表 439

CWE-23 相对路径遍历 类弱点 439 条 CVE 漏洞汇总，含 AI 中文分析。

CWE-23 相对路径遍历漏洞源于软件未正确过滤外部输入中的“..”序列，导致构造的文件路径突破受限目录边界。攻击者通常利用此缺陷读取或修改系统敏感文件，获取未授权访问权限。开发者应避免直接使用用户输入拼接路径，需通过白名单验证、规范化路径或限制访问范围来彻底中和危险字符，从而防止路径逃逸。

MITRE CWE 官方描述
CWE：CWE-23 Relative Path Traversal（相对路径遍历） 英文：产品使用外部输入来构建一个应位于受限目录内的路径名，但它未能正确中和（neutralize）诸如“..”之类的序列，这些序列可解析为该目录之外的位置。
常见影响 (4)
Integrity, Confidentiality, Availability Execute Unauthorized Code or Commands
The attacker may be able to create or overwrite critical files that are used to execute code, such as programs or libraries.
Integrity Modify Files or Directories
The attacker may be able to overwrite or create critical files, such as programs, libraries, or important data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, appending a new account at the end of a password file may allow …
Confidentiality Read Files or Directories
The attacker may be able read the contents of unexpected files and expose sensitive data by traversing the file system to access files or directories that are outside of the restricted directory. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mech…
Availability DoS: Crash, Exit, or Restart
The attacker may be able to overwrite, delete, or corrupt unexpected critical files such as programs, libraries, or important data. This may prevent the product from working at all and in the case of a protection mechanisms such as authentication, it has the potential to lockout every user of the pr…

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. Use a built-in path canonicalization function (such as realpath(…
Operation Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].

Attack · Other
The following code could be for a social networking application in which each user's profile information is stored in a separate file. All files are stored in a single directory.
my $dataPath = "/users/cwe/profiles"; my $username = param("user"); my $profilePath = $dataPath . "/" . $username; open(my $fh, "<", $profilePath) || ExitError("profile read error: $profilePath"); print "<ul>\n"; while (<$fh>) { print "<li>$_</li>\n"; } print "</ul>\n";
