Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-43: Path Equivalence: 'filename....' (Multiple Trailing Dot), where 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. In Melisplatform/melis cms slider, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.
