CVE-2024-32876 – NewPipe has potential security vulnerability when importing settings

https://notcve.org/view.php?id=CVE-2024-32876

NewPipe is an Android app for video streaming written in Java. It supports exporting and importing backups, as a way to let users move their data to a new device effortlessly. However, in versions 0.13.4 through 0.26.1, importing a backup file from an untrusted source could have resulted in Arbitrary Code Execution. This is because backups are serialized/deserialized using Java's Object Serialization Stream Protocol, which can allow constructing any class in the app, unless properly restricted. To exploit this vulnerability, an attacker would need to build a backup file containing the exploit, and then persuade a user into importing it. During the import process, the malicious code would be executed, possibly crashing the app, stealing user data from the NewPipe app, performing nasty actions through Android APIs, and attempting Android JVM/Sandbox escapes through vulnerabilities in the Android OS. The attack can take place only if the user imports a malicious backup file, so an attacker would need to trick a user into importing a backup file from a source they can control. • https://docs.oracle.com/javase/6/docs/platform/serialization/spec/protocol.html https://github.com/TeamNewPipe/NewPipe/commit/a69bbab73220f36e53c801cf7e9ea3627bb017eb https://github.com/TeamNewPipe/NewPipe/releases/tag/v0.27.0 https://github.com/TeamNewPipe/NewPipe/security/advisories/GHSA-wxrm-jhpf-vp6v • CWE-502: Deserialization of Untrusted Data •
