CVE-2022-47757Network attack vector

Arbitrary code execution via deeplink path traversal

Published May 4, 2023 · Updated Feb 3, 2025

Path traversal in imo.im for Android before 2022.11.2011 allows context-dependent attackers to execute code via a crafted deeplink. The deeplink handler fails to sanitize a destination path, allowing a downloaded shared library to be written into the module-loading directory. Exploitation requires a user to open the crafted deeplink; dynamic loading then runs the library with the application's privileges.
