db4web_c and db4web_c.exe programs in DB4Web 3.4 and 3.6 allow remote attackers to read arbitrary files via an HTTP request whose argument is a filename of the form (1) C: (drive letter), (2) //absolute/path (double-slash), or (3) .. (dot-dot).

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.
CVE-2004-0578: Server allows remote attackers to read ar
CWE
Absolute Path Traversal
mitre_cwe
CWE-36 Absolute Path Traversal
CWE-36: Absolute Path Traversal
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as "/abs/path" 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.
Modes of Introduction:
Phase: Implementation
Common Consequences:
Scope: Integrity, Confidentiality, Availability. Impact: 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.
Scope: Integrity. Impact: Modify Files or Directories. The attacker may be able to overwrite or create
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.
Modes of Introduction:
Phase: Implementation
Common Consequences:
Scope: Confidentiality, Integrity, Access Control. Impact: Read Files or Directories, Modify Files or Directories, Bypass Protection Mechanism. A
CWE
Path Equivalence: '/multiple//internal/slash'
mitre_cwe·CVSS 5.0
[MEDIUM] CWE-51 Path Equivalence: '/multiple//internal/slash'
CWE-51: Path Equivalence: '/multiple//internal/slash'
The product accepts path input in the form of multiple internal slash ('/multiple//internal/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.
Potential Mitigations:
[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 vali
CWE
Path Traversal: 'C:dirname'
mitre_cwe
CWE-39 Path Traversal: 'C:dirname'
CWE-39: Path Traversal: 'C:dirname'
The product accepts input that contains a drive letter or Windows volume letter ('C:dirname') that potentially redirects access to an unintended location or arbitrary file.
Modes of Introduction:
Phase: Implementation
Common Consequences:
Scope: Integrity, Confidentiality, Availability. Impact: 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.
Scope: Integrity. Impact: 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
