CWE
Path Equivalence: '//multiple/leading/slash'
mitre_cwe·CVSS 5.0
[MEDIUM] CWE-50 Path Equivalence: '//multiple/leading/slash'
CWE-50: Path Equivalence: '//multiple/leading/slash'
The product accepts path input in the form of multiple leading slash ('//multiple/leading/slash') 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.
Modes of Introduction:
Phase: Implementation
Common Consequences:
Scope: Confidentiality, Integrity. Impact: Read Files or Directories, Modify Files or Directories.
Observed Examples:
CVE-2002-1483: Read files with full pathname using multiple internal slash.
CVE-1999-1456: Server allows remote attackers to read arbitrary files via a GET request with more than one leading / (slash) character in the filename.

CWE
Improper Resolution of Path Equivalence
mitre_cwe
CWE-41 Improper Resolution of Path Equivalence
CWE-41: Improper Resolution of Path Equivalence
The product is vulnerable to file system contents disclosure through path equivalence. Path equivalence involves the use of special characters in file and directory names. The associated manipulations are intended to generate multiple names for the same object.
Path equivalence is usually employed in order to circumvent access controls expressed using an incomplete set of file name or file path representations. This is different from path traversal, wherein the manipulations are performed to generate a name for a different object.

CWE
Improper Neutralization of Multiple Leading Special Elements
mitre_cwe
CWE-161 Improper Neutralization of Multiple Leading Special Elements
CWE-161: Improper Neutralization of Multiple Leading Special Elements
The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes multiple leading special elements that could be interpreted in unexpected ways when they are sent to a downstream component.
As data is parsed, improperly handled multiple leading special elements may cause the process to take unexpected actions that result in an attack.
Modes of Introduction:
Phase: Implementation
Common Consequences:
Scope: Integrity. Impact: Unexpected State.
Potential Mitigations:
Developers should anticipate that multiple leading special elements will be injected/removed/manipulated in the input vectors of their product. Use an appropriate combination of denylists and allowlists to ensur
