Official description
Path Traversal: 'dir/../../filename' vulnerability in Yordam Information Technology Consulting Education and Electrical Systems Industry Trade Inc. Yordam Katalog allows Path Traversal. This issue affects Yordam Katalog: before 21.7.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Path Traversal: 'dir/../../filename'
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize multiple internal../ 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.
