Internal service access via followed assetlinks redirects
Published Dec 3, 2024 · Updated Dec 3, 2024
SSRF in MobSF before 3.9.7 allows remote attackers to reach internal services through a crafted assetlinks.json redirect. The _check_url method passes allow_redirects=True to requests.get, so an external URL can return HTTP 302 and make MobSF follow the Location target. No privileges or user interaction are required; the server can send requests to internal-only services reachable from its network context.
