Technical ContextAI · show details
This vulnerability is classified as Path Traversal (CWE-22), which allows attackers to access files and directories outside the intended path. 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. Affected products include: Deltaww Dialink.
