Advisories for Pypi/Mobsf package

The vulnerability allows any user to overwrite any files available under the account privileges of the running process.

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.

The fix for the "SSRF Vulnerability on assetlinks_check(act_name, well_knowns)" vulnerability could potentially be bypassed.

Vulnerable MobSF Versions: <= v4.3.2 CVSS V4.0 Score: 8.6 (CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N) Details: A Stored Cross-Site Scripting (XSS) vulnerability has been identified in MobSF versions ≤ 4.3.2. The vulnerability arises from improper sanitization of user-supplied SVG files during the Android APK analysis workflow. When an Android Studio project contains a malicious SVG file as an app icon (e.g path, /app/src/main/res/mipmap-hdpi/ic_launcher.svg), and the project is zipped and uploaded to MobSF, the tool processes …

The latest deployed fix for the SSRF vulnerability is through the use of the call valid_host(). The code available at lines /ae34f7c055aa64fca58e995b70bc7f19da6ca33a/mobsf/MobSF/utils.py #L907-L957 is vulnerable to SSRF abuse using DNS rebinding technique.

The application allows users to upload files with scripts in the filename parameter. As a result, a malicious user can upload a script file to the system. When users in the application use the "Diff or Compare" functionality, they are affected by a Stored Cross-Site Scripting vulnerability.

Upon reviewing the MobSF source code, I identified a flaw in the Static Libraries analysis section. Specifically, during the extraction of .a extension files, the measure intended to prevent Zip Slip attacks is improperly implemented. Since the implemented measure can be bypassed, the vulnerability allows an attacker to extract files to any desired location within the server running MobSF.

An open redirect vulnerability exist in MobSF authentication view. PoC Go to http://127.0.0.1:8000/login/?next=//afine.com in a web browser. Enter credentials and press "Sign In". You will be redirected to afine.com Users who are not using authentication are not impacted.

What kind of vulnerability is it? Who is impacted? SSRF vulnerability in firebase database check logic. The attacker can cause the server to make a connection to internal-only services within the organization’s infrastructure. When malicious app is uploaded to Static analyzer, it is possible to make internal requests. Credits: Oleg Surnin (Positive Technologies).

Mobile Security Framework (MobSF) <=v3.7.8 Beta is vulnerable to Insecure Permissions.

Mobile Security Framework (MobSF) v0.9.2 and below was discovered to contain a local file inclusion (LFI) vulnerability in the StaticAnalyzer/views.py script. This vulnerability allows attackers to read arbitrary files via a crafted HTTP request.
