{"id":"CVE-2025-34095","state":"PUBLISHED","title":"Mako Server v2.5 and v2.6 OS Command Injection via examples/save.lsp","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.","publishedAt":"2025-07-10T19:14:30.933Z","updatedAt":"2026-05-14T02:07:36.308Z","severity":{"score":9.3,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["Real Time Logic Mako Server"],"affected":[{"vendor":"Real Time Logic","product":"Mako Server","defaultStatus":"unaffected","versions":[{"version":"2.5","status":"affected","lessThanOrEqual":"2.6","versionType":"custom"}],"modules":["examples/save.lsp","examples/manage.lsp","HTTP body content passed to save.lsp (with ex=2.1 GET parameter)"]}],"references":["https://raw.githubusercontent.com/rapid7/metasploit-framework/master/modules/exploits/multi/http/makoserver_cmd_exec.rb","https://www.exploit-db.com/exploits/43132","https://vulncheck/advisories/mako-server-rce"],"weaknesses":["CWE-78"],"ingestedAt":"2026-10-29T20:09:03.054Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/34xxx/CVE-2025-34095.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-34095","state":"PUBLISHED","datePublished":"2025-07-10T19:14:30.933Z","dateUpdated":"2026-05-14T02:07:36.308Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2025-04-15T19:15:22.552Z"},"containers":{"cna":{"title":"Mako Server v2.5 and v2.6 OS Command Injection via examples/save.lsp","descriptions":[{"lang":"en","value":"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.
