Directory traversal issues in the D-Mod extractor in DFArc and DFArc2 (as well as in RTsoft's Dink Smallwood HD / ProtonSDK version) before 3.14 allow an attacker to overwrite arbitrary files on the user's system.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
