An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-33841 in the wild and no public exploit code.\n\nAffected product: Circutor SGE-PLC1000. 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-2021-33841/ (Markdown: https://insights.sbomify.com/CVE-2021-33841/index.md)","id":"CVE-2021-33841","markdown":"https://insights.sbomify.com/CVE-2021-33841/index.md","name":"CVE-2021-33841","record":{"aliases":["GHSA-56hw-2q6h-3vh6"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"PLC device","requires_auth":"none","summary":"Remote attackers can inject OS commands with maximum privileges on Circutor SGE-PLC1000 devices due to improper request handling.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"INCIBE","cpe":[{"product":"sge-plc1000_firmware","vendor":"circutor"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"SGE-PLC1000 device, in its 0.9.2b firmware version, does not handle some requests correctly, allowing a remote attacker to inject code into the operating system with maximum privileges.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Circutor SGE-PLC1000 OS command Injection","id":"CVE-2021-33841","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Circutor SGE-PLC1000 improper authentication","id":"CVE-2021-33842"},"packages":[],"prev":{"headline":"Business logic in n/a","id":"CVE-2021-33840"},"products":["SGE-PLC1000"],"published":"2021-06-09","related":[{"cvss_score":10,"headline":"Stack-based buffer overflow vulnreability in Circutor SGE-PLC1000/SGE-PLC50","id":"CVE-2025-11778","kev_date_added":null,"published":"2025-12-02"},{"cvss_score":9.4,"headline":"Stack-based buffer overflow vulnreability in Circutor SGE-PLC1000/SGE-PLC50","id":"CVE-2025-11779","kev_date_added":null,"published":"2025-12-02"},{"cvss_score":8.8,"headline":"Circutor SGE-PLC1000 improper authentication","id":"CVE-2021-33842","kev_date_added":null,"published":"2021-06-09"},{"cvss_score":8.7,"headline":"Stack-based buffer overflow vulnreability in Circutor SGE-PLC1000/SGE-PLC50","id":"CVE-2025-11780","kev_date_added":null,"published":"2025-12-02"},{"cvss_score":8.6,"headline":"Use of hardcoded cryptographic keys in Circutor SGE-PLC1000/SGE-PLC50","id":"CVE-2025-11781","kev_date_added":null,"published":"2025-12-02"},{"cvss_score":8.5,"headline":"Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50","id":"CVE-2025-11782","kev_date_added":null,"published":"2025-12-02"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["Circutor"]},"summary":"Remote attackers can inject OS commands with maximum privileges on Circutor SGE-PLC1000 devices due to improper request handling.","url":"https://insights.sbomify.com/CVE-2021-33841/"}
