Exploitation Summary

EIP tracks 2 public exploits for CVE-2025-34095. PoCs published by Metasploit, John Page (hyp3rlinx) - Beyond Security SecuriTeam Secure Disclosure, including Metasploit module exploits/multi/http/makoserver_cmd_exec.

AI-analyzed exploit summary This Metasploit module exploits a command injection vulnerability in Mako Server v2.5 by sending a PUT request to save.lsp to store a malicious payload and a GET request to manage.lsp to execute it, achieving remote code execution.

Description

An OS command injection vulnerability exists in Mako Server versions 2.5 and 2.6, specifically within the tutorial interface provided by the examples/save.lsp endpoint. An unauthenticated attacker can send a crafted PUT request containing arbitrary Lua os.execute() code, which is then persisted on disk and triggered via a subsequent GET request to examples/manage.lsp. This allows remote command execution on the underlying operating system, impacting both Windows and Unix-based deployments.
