MobSF vulnerabilities

Mobile Security Framework (MobSF) v4.5.2 is vulnerable to Command Injection in /download_data/, /api/v1/scan, Dynamic Analyzer ADB integration module.

Vulnerability in MobSF before version 4.5.1. The get_browsable_activities function in manifest_analysis.py validates only the android:host value, not android:port, allowing an authenticated user to upload a crafted APK that makes requests to an attacker-selected nonstandard port at /.well-known/assetlinks.json. With DNS rebinding, the request can reach an internal service. Fixed in version 4.5.1.

MobSF, a mobile application security testing tool, prior to 4.5.1 contains a vulnerability in the unzip function in mobsf/StaticAnalyzer/views/common/shared_func.py that logs that an archive member exceeding ZIP_MAX_UNCOMPRESSED_FILE_SIZE is being skipped but does not continue to the next member. An authenticated user can upload a crafted ZIP or APK whose oversized member is extracted to disk when the aggregate ZIP_MAX_UNCOMPRESSED_TOTAL_SIZE limit has not yet been reached, potentially exhausting disk space and preventing further scans. This issue is fixed in version 4.5.1.

MobSF, a mobile application security testing tool, prior to 4.5.1 contains a vulnerability where django.middleware.csrf.CsrfViewMiddleware is placed only in the deprecated MIDDLEWARE_CLASSES setting and omitted from the active MIDDLEWARE tuple, allowing a remote attacker to make a logged-in victim submit cross-site POST requests to authenticated web endpoints including /delete_scan/, /upload/, /download_scan/, /change_password/, /create_user/, and /delete_user/. This can delete scans, upload or download applications, change passwords, or manage users with the victim account permissions. This issue is fixed in version 4.5.1.

MobSF, a mobile application security testing tool, prior to 4.5.1 contains a vulnerability in find_icon_path_zip in mobsf/StaticAnalyzer/views/android/icon_analysis.py that uses the Android manifest android:icon value to construct paths under the scan resource directory without rejecting traversal or verifying containment. An authenticated user can upload a crafted ZIP or APK that reads a server file with an ALLOWED_EXTENSIONS suffix, copies it to DWD_DIR as the predictable name -icon., and retrieves it through the /download/ endpoint. The same behavior provides a file-existence oracle through the icon_path report field. This issue is fixed in version 4.5.1.

In MobSF version 4.4.0, an authenticated user who uploaded a specially prepared one.a can write arbitrary files to any directory writable by the MobSF process user. This issue is patched in version 4.4.1.

In MobSF version 4.4.0, the GET /download/ route uses os.path.commonprefix for path verification, allowing an authenticated user to download files outside the DWD_DIR download directory from neighboring directories whose absolute paths share the same prefix (e.g., downloads_bak, downloads.old). This is a directory traversal leading to data leakage. The issue is patched in version 4.4.1.
