Weaknesses that lead here
Classes of exploited vulnerability that CTID maps to this technique.
- CWE-223 KEV CVEsImproper Limitation of a Pathname to a Restricted Directory ('Path Traversal')Sequences like ../ in a file path escape the intended folder, exposing or overwriting other files.
- CWE-233 KEV CVEsRelative Path TraversalRelative ../ segments in input climb out of the allowed directory.
- CWE-363 KEV CVEsAbsolute Path TraversalAn absolute path in input points straight at a file outside the allowed directory.
- CWE-2871 KEV CVEImproper AuthenticationThe system doesn't properly prove who a user is, so attackers get in as someone else.
- CWE-2881 KEV CVEAuthentication Bypass Using an Alternate Path or ChannelA second route (a debug port, an API) reaches the protected function without the login check.
- CWE-2901 KEV CVEAuthentication Bypass by SpoofingThe system trusts something an attacker can fake, such as a source address or header.
- CWE-3061 KEV CVEMissing Authentication for Critical FunctionA sensitive function requires no login at all; one of the most exploited flaws in edge devices.
