CWE
Incorrect Behavior Order: Validate Before Canonicalize
mitre_cwe·CVSS 5.0
[MEDIUM] CWE-180 Incorrect Behavior Order: Validate Before Canonicalize
CWE-180: Incorrect Behavior Order: Validate Before Canonicalize
The product validates input before it is canonicalized, which prevents the product from detecting data that becomes invalid after the canonicalization step.
This can be used by an attacker to bypass the validation and launch attacks that expose weaknesses that would otherwise be prevented, such as injection.
Modes of Introduction:
Phase: Implementation
Common Consequences:
Scope: Access Control. Impact: Bypass Protection Mechanism.
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
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: 'fakedir/../realdir/filename'
mitre_cwe·CVSS 10.0
[CRITICAL] CWE-57 Path Equivalence: 'fakedir/../realdir/filename'
CWE-57: Path Equivalence: 'fakedir/../realdir/filename'
The product contains protection mechanisms to restrict access to 'realdir/filename', but it constructs pathnames using external input in the form of 'fakedir/../realdir/filename' that are not handled by those mechanisms. This allows attackers to perform unauthorized actions against the targeted file.
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 use
CWE
Incorrect Behavior Order: Early Validation
mitre_cwe
CWE-179 Incorrect Behavior Order: Early Validation
CWE-179: Incorrect Behavior Order: Early Validation
The product validates input before applying protection mechanisms that modify the input, which could allow an attacker to bypass the validation via dangerous inputs that only arise after the modification.
Product needs to validate data at the proper time, after data has been canonicalized and cleansed. Early validation is susceptible to various manipulations that result in dangerous inputs that are produced by canonicalization and cleansing.
Modes of Introduction:
Phase: Implementation
Note: Since early validation errors usually arise from improperly implemented defensive mechanisms, it is likely that these will be introduced more frequently as secure programming becomes implemented more widely.
Common Consequences:
Scope: Access Cont
