Authenticated arbitrary file overwrite via absolute archive paths
Published Sep 2, 2025 · Updated Sep 2, 2025
Path traversal in MobSF 4.4.0 allows remote authenticated users to overwrite process-writable files through a crafted .a upload. The ar_extract function decodes each archive member name, checks only relative traversal patterns, then joins it with the analysis directory; an absolute name replaces that root and is written directly. High-privilege MobSF access is required, and writes are limited to paths writable by the MobSF process, enabling report tampering or a service crash.
