Authenticated SSRF via DNS-rebinding host validation bypass
Published Mar 31, 2025 · Updated Mar 31, 2025
SSRF in Mobile Security Framework before 4.3.2 allows remote authenticated users to access internal resources through DNS rebinding. The asset-links path calls valid_host(), which resolves an attacker-controlled hostname once for filtering before requests.get resolves it again for retrieval. A high-privilege account must submit crafted Android application metadata; the server can then contact a private HTTP service and expose limited data or interrupt that service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
