Official description

Path Traversal: '.../...//' vulnerability in VibeThemes WPLMS wplms_plugin allows Path Traversal.This issue affects WPLMS: from n/a through < 1.9.9.5.2.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Path Traversal: '.../...//'

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '.../...//' (doubled triple dot slash) sequences that can resolve to a location that is outside of that directory.

How developers prevent this class of flaw

  • 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 validation schemes by introducing dangerous inputs after they have been checked.
