In NSA Ghidra before 9.1, path traversal can occur in RestoreTask.java (from the package ghidra.app.plugin.core.archive) via an archive with an executable file that has an initial ../ in its filename. This allows attackers to overwrite arbitrary files in scenarios where an intermediate analysis result is archived for sharing with other persons. To achieve arbitrary code execution, one approach is to overwrite some critical Ghidra modules, e.g., the decompile module.
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.
