title: ICSA-22-307-03 Delta Industrial Automation DIALink Path traversal
description: Delta Industrial Automation DIALink versions prior to v1.5.0.0 Beta 4 uses an external input to construct a pathname intended to identify a file or directory located underneath a restricted parent directory. However, the software does not properly neutralize special elements within the pathname, which can cause the pathname to resolve to a location outside of the restricted directory.
