An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-27175 exists.\n\nAffected product: sergejey MajorDoMo. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-27175/ (Markdown: https://insights.sbomify.com/CVE-2026-27175/index.md)","id":"CVE-2026-27175","markdown":"https://insights.sbomify.com/CVE-2026-27175/index.md","name":"CVE-2026-27175","record":{"aliases":["GHSA-jmf5-x823-23g3"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MajorDoMo home automation","requires_auth":"none","summary":"Unauthenticated attackers can achieve remote code execution in MajorDoMo by exploiting a race condition in the command queue processing.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"majordomo","vendor":"mjdm"}],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"MajorDoMo (aka Major Domestic Module) is vulnerable to unauthenticated OS command injection via rc/index.php. The $param variable from user input is interpolated into a command string within double quotes without sanitization via escapeshellarg(). The command is inserted into a database queue by safe_exec(), which performs no sanitization. The cycle_execs.php script, which is web-accessible without authentication, retrieves queued commands and passes them directly to exec(). An attacker can exploit a race condition by first triggering cycle_execs.php (which purges the queue and enters a polling loop), then injecting a malicious command via the rc endpoint while the worker is polling. The injected shell metacharacters expand inside double quotes, achieving remote code execution within one second.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-02-18","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2026-02-18","kind":"metasploit","ref":"exploit/multi/http/majordomo_cmd_injection_rce","stars":null,"title":"MajorDoMo Remote Command Injection via cycle_execs Race Condition"}],"tier":"weaponised"},"has_fix":null,"headline":"MajorDoMo Command Injection in rc/index.php via Race Condition","id":"CVE-2026-27175","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"MajorDoMo Reflected Cross-Site Scripting in command.php","id":"CVE-2026-27176"},"packages":[],"prev":{"headline":"MajorDoMo Unauthenticated Remote Code Execution via Admin Console Eval","id":"CVE-2026-27174"},"products":["MajorDoMo"],"published":"2026-02-18","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2023-50917","kev_date_added":null,"published":"2023-12-15"},{"cvss_score":9.3,"headline":"MajorDoMo Unauthenticated Remote Code Execution via Admin Console Eval","id":"CVE-2026-27174","kev_date_added":null,"published":"2026-02-18"},{"cvss_score":9.3,"headline":"MajorDoMo Supply Chain Remote Code Execution via Update URL Poisoning","id":"CVE-2026-27180","kev_date_added":null,"published":"2026-02-18"},{"cvss_score":8.8,"headline":"MajorDoMo Unauthenticated SQL Injection in Commands Module","id":"CVE-2026-27179","kev_date_added":null,"published":"2026-02-18"},{"cvss_score":8.7,"headline":"MajorDoMo Unauthenticated Module Uninstall via Market Endpoint","id":"CVE-2026-27181","kev_date_added":null,"published":"2026-02-18"},{"cvss_score":5.3,"headline":"MajorDoMo Stored Cross-Site Scripting via Property Set Endpoint","id":"CVE-2026-27177","kev_date_added":null,"published":"2026-02-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-23","vendors":["sergejey"]},"summary":"Unauthenticated attackers can achieve remote code execution in MajorDoMo by exploiting a race condition in the command queue processing.","url":"https://insights.sbomify.com/CVE-2026-27175/"}
