CVE-2020-7882Network attack vector

File information disclosure via unchecked path resolution

Published Nov 22, 2021 · Updated Aug 4, 2024

Path traversal in Hancom WITH AnySign4PC 1.1.1.0, 1.1.2.6, and 1.1.2.7 allows remote attackers to disclose file information. The getPFXFolderList function resolves a path parameter containing ../ sequences outside the intended certificate folder instead of restricting traversal. No authentication or user interaction is required; KrCERT also states that the function can delete files on affected Windows hosts.
