名前: Path Equivalence: '/./' (Single Dot Directory)

The product accepts path input in the form of single dot directory exploit ('/./') without appropriate validation, which can lead to ambiguous path resolution and allow an attacker to traverse the file system to unintended locations or access arbitrary files.

参考文献 説明

CVE-2024-6091

Chain: AI agent platform does not restrict pathnames containing internal "/./" sequences (CWE-55), leading to an incomplete denylist (CWE-184) that does not prevent OS command injection (CWE-78)

CVE-2000-0004

Server allows remote attackers to read source code for executable files by inserting a . (dot) into the URL.

CVE-2002-0304

Server allows remote attackers to read password-protected files via a /./ in the HTTP request.

CVE-1999-1083

Possibly (could be a cleansing error)

CVE-2004-0815

"/./////etc" cleansed to ".///etc" then "/etc"

CVE-2002-0112

Server allows remote attackers to view password protected files via /./ in the URL.

潜在的な緩和策

Phases : 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.

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.
