CWE-42Path Equivalence: 'filename.' (Trailing Dot)The product accepts path input in the form of trailing dot ('filedir.') 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.
CWE-43Path Equivalence: 'filename....' (Multiple Trailing Dot)The product accepts path input in the form of multiple trailing dot ('filedir....') 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.
CWE-44Path Equivalence: 'file.name' (Internal Dot)The product accepts path input in the form of internal dot ('file.ordir') 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.
CWE-45Path Equivalence: 'file...name' (Multiple Internal Dot)The product accepts path input in the form of multiple internal dot ('file...dir') 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.
CWE-46Path Equivalence: 'filename ' (Trailing Space)The product accepts path input in the form of trailing space ('filedir ') 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.
CWE-47Path Equivalence: ' filename' (Leading Space)The product accepts path input in the form of leading space (' filedir') 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.
CWE-48Path Equivalence: 'file name' (Internal Whitespace)The product accepts path input in the form of internal space ('file(SPACE)name') 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.
CWE-49Path Equivalence: 'filename/' (Trailing Slash)The product accepts path input in the form of trailing slash ('filedir/') 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.
CWE-50Path 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.
CWE-51Path 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.
CWE-52Path Equivalence: '/multiple/trailing/slash//'The product accepts path input in the form of multiple trailing slash ('/multiple/trailing/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.
CWE-53Path Equivalence: '\multiple\\internal\backslash'The product accepts path input in the form of multiple internal backslash ('\multiple\trailing\\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.
CWE-54Path Equivalence: 'filedir\' (Trailing Backslash)The product accepts path input in the form of trailing backslash ('filedir\') 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.
CWE-55Path 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.
CWE-56Path Equivalence: 'filedir*' (Wildcard)The product accepts path input in the form of asterisk wildcard ('filedir*') 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.
CWE-57Path 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.
CWE-58Path Equivalence: Windows 8.3 FilenameThe product contains a protection mechanism that restricts access to a long filename on a Windows operating system, but it does not properly restrict access to the equivalent short "8.3" filename.
CWE-59Improper Link Resolution Before File Access ('Link Following')The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
CWE-61UNIX Symbolic Link (Symlink) FollowingThe product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.
CWE-62UNIX Hard LinkThe product, when opening a file or directory, does not sufficiently account for when the name is associated with a hard link to a target that is outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.
CWE-64Windows Shortcut Following (.LNK)The product, when opening a file or directory, does not sufficiently handle when the file is a Windows shortcut (.LNK) whose target is outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.
CWE-65Windows Hard LinkThe product, when opening a file or directory, does not sufficiently handle when the name is associated with a hard link to a target that is outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.
CWE-66Improper Handling of File Names that Identify Virtual ResourcesThe product does not handle or incorrectly handles a file name that identifies a "virtual" resource that is not directly specified within the directory that is associated with the file name, causing the product to perform file-based operations on a resource that is not a file.
CWE-67Improper Handling of Windows Device NamesThe product constructs pathnames from user input, but it does not handle or incorrectly handles a pathname containing a Windows device name such as AUX or CON. This typically leads to denial of service or an information exposure when the application attempts to process the pathname as a regular file.
CWE-69Improper Handling of Windows ::DATA Alternate Data StreamThe product does not properly prevent access to, or detect usage of, alternate data streams (ADS).
CWE-72Improper Handling of Apple HFS+ Alternate Data Stream PathThe product does not properly handle special paths that may identify the data or resource fork of a file on the HFS+ file system.
