CVE-2025-34095 – Mako Server v2.5 and v2.6 OS Command Injection via examples/save.lsp

https://notcve.org/view.php?id=CVE-2025-34095

10 Jul 2025 — 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. • https://raw.githubusercontent.com/rapid7/metasploit-framework/master/modules/exploits/multi/http/makoserver_cmd_exec.rb • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
