Description

Appium is an automation framework that provides WebDriver-based automation possibilities for a wide range platforms. Prior to 7.0.6, @appium/support contains a ZIP extraction implementation (extractAllTo() via ZipExtractor.extract()) with a path traversal (Zip Slip) check that is non-functional. The check at line 88 of packages/support/lib/zip.js creates an Error object but never throws it, allowing malicious ZIP entries with ../ path components to write files outside the intended destination directory. This affects all JS-based extractions (the default code path), not only those using the fileNamesEncoding option. This vulnerability is fixed in 7.0.6.

• CWE-22Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')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.
