Code execution via unchecked ZIP entry paths
Published Apr 5, 2024 · Updated Aug 16, 2024
Path traversal in zly2006 Reden before 0.2.514 allows remote attackers to write arbitrary client files through a crafted ZIP packet. KeyCallbacks.kt resolves each server-supplied ZipEntry name beneath DEBUG_RVC_REQUEST_SYNC_DATA and writes its bytes without normalizing the result or verifying that it remains under that directory. Exploitation requires the client to join a malicious server and invoke the debug keybind; a JAR written into the mods directory executes when Minecraft loads it.

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.
