CVE-2025-58161: MobSF Path Traversal in GET /download/<filename> using absolute filenames

Noroxi assessment

Priority: Monitor (action score 5/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.79% (FIRST EPSS); higher than 56.5% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: MobSF Mobile-Security-Framework-MobSF 4.4.1.

Low priority for now. Upgrade to MobSF Mobile-Security-Framework-MobSF 4.4.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

MobSF is a mobile application security testing tool used. In version 4.4.0, the GET /download/ route uses string path verification via os.path.commonprefix, which allows an authenticated user to download files outside the DWD_DIR download directory from "neighboring" directories whose absolute paths begin with the same prefix as DWD_DIR (e.g., .../downloads_bak, .../downloads.old). This is a Directory Traversal (escape) leading to a data leak. This issue has been patched in version 4.4.1.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.
