Description

androidqf: Zip entry Name Injection in APK bundle (Zip Slip for zip consumers)

Summary

generateZipPath() constructs zip entry names for collected APKs using device controlled content from extractFileName(). Since extractFileName() does not reject traversal sequences, the resulting zip entry name can contain ../. AndroidQF itself does not extract the zip it creates, but any forensic tool that extracts the acquisition bundle without zip-slip protection could write files to attacker chosen paths.

Impact

A compromised device could inject path traversal sequences into the acquisition bundle's zip entry names. When a forensic analyst or forensic tooling extracts the bundle without entry name validation, files could be written outside the intended extraction directory.
