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-2011-4861 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2011-4861/ (Markdown: https://insights.sbomify.com/CVE-2011-4861/index.md)","id":"CVE-2011-4861","markdown":"https://insights.sbomify.com/CVE-2011-4861/index.md","name":"CVE-2011-4861","record":{"aliases":["GHSA-qjpg-9j88-997j"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Schneider Electric PLC","requires_auth":"none","summary":"Remote attackers can install arbitrary firmware on Schneider Electric Quantum Ethernet Modules via MODBUS, leading to full device compromise.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"quantum_ethernet_module_140noe77100","vendor":"schneider-electric"},{"product":"quantum_ethernet_module_140noe77101","vendor":"schneider-electric"},{"product":"quantum_ethernet_module_140noe77111","vendor":"schneider-electric"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"AV:N/AC:L/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"The modbus_125_handler function in the Schneider Electric Quantum Ethernet Module on the NOE 771 device (aka the Quantum 140NOE771* module) allows remote attackers to install arbitrary firmware updates via a MODBUS 125 function code to TCP port 502.","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":"Missing authorization in n/a","id":"CVE-2011-4861","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2011"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2011-4862"},"packages":[],"prev":{"headline":"Hardcoded credentials in n/a","id":"CVE-2011-4860"},"products":["n/a"],"published":"2011-12-17","related":[{"cvss_score":10,"headline":"Hardcoded credentials in n/a","id":"CVE-2011-4860","kev_date_added":null,"published":"2011-12-17"}],"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":["n/a"]},"summary":"Remote attackers can install arbitrary firmware on Schneider Electric Quantum Ethernet Modules via MODBUS, leading to full device compromise.","url":"https://insights.sbomify.com/CVE-2011-4861/"}
