Arbitrary file read via unanchored MD5 validation
Published Oct 18, 2022 · Updated May 10, 2025
Local file inclusion in MobSF 0.9.2 and earlier allows remote attackers to read arbitrary files through the ViewSource endpoint. The endpoint validates only a 32-hexadecimal prefix of the md5 parameter, then accepts trailing path traversal and null-byte data in a filesystem path. Unauthenticated network access is sufficient, and disclosure is limited to files readable by the MobSF server process.
