An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-6979 and fix it if it is affected.\n\nWhat it is: CVE-2020-6979 is a high-severity vulnerability in Moxa EDS-G516E Series firmware, Version 5.2 or lower, published on 24 Mar 2020. 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-2020-6979 in the wild and no public exploit code.\n\nAffected product: Moxa EDS-G516E Series firmware, Version 5.2 or lower. 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-2020-6979/ (Markdown: https://insights.sbomify.com/CVE-2020-6979/index.md)","id":"CVE-2020-6979","markdown":"https://insights.sbomify.com/CVE-2020-6979/index.md","name":"CVE-2020-6979","record":{"aliases":["GHSA-rh3w-9rw6-jh3x"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Ethernet Switch","requires_auth":"none","summary":"Attackers can recover confidential data from Moxa EDS-G516E switches due to the use of a hard-coded cryptographic key in the firmware.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"eds-510e_firmware","vendor":"moxa"},{"product":"eds-g516e_firmware","vendor":"moxa"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"},{"id":"CWE-321","name":"Use of Hard-coded Cryptographic Key"}],"description":"In Moxa EDS-G516E Series firmware, Version 5.2 or lower, the affected products use a hard-coded cryptographic key, increasing the possibility that confidential data can be recovered.","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":"Hardcoded credentials in Moxa EDS-G516E Series firmware, Version 5.2 or lower","id":"CVE-2020-6979","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Rockwell Automation MicroLogix 1400 Controllers Series B v21.001 and prior, Series A, all versions, MicroLogix 1100 Controller, all versions, RSLogix 500 Software v12.001 and prior","id":"CVE-2020-6980"},"packages":[],"prev":{"headline":"Supply chain in Honeywell WIN-PAK 4.7.2, Web and prior versions","id":"CVE-2020-6978"},"products":["Moxa EDS-G516E Series firmware, Version 5.2 or lower"],"published":"2020-03-24","related":[{"cvss_score":9.8,"headline":"Hardcoded credentials in Moxa EDS-G516E Series firmware, Version 5.2 or lower","id":"CVE-2020-6981","kev_date_added":null,"published":"2020-03-24"},{"cvss_score":9.8,"headline":"Weak cryptography in Moxa EDS-G516E Series firmware, Version 5.2 or lower","id":"CVE-2020-6991","kev_date_added":null,"published":"2020-03-24"},{"cvss_score":9.8,"headline":"Memory corruption in Moxa EDS-G516E Series firmware, Version 5.2 or lower","id":"CVE-2020-7007","kev_date_added":null,"published":"2020-03-24"},{"cvss_score":7.5,"headline":"Information disclosure in Moxa EDS-G516E Series firmware, Version 5.2 or lower","id":"CVE-2020-6997","kev_date_added":null,"published":"2020-03-24"},{"cvss_score":7.5,"headline":"Weak cryptography in Moxa EDS-G516E Series firmware, Version 5.2 or lower","id":"CVE-2020-7001","kev_date_added":null,"published":"2020-03-24"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can recover confidential data from Moxa EDS-G516E switches due to the use of a hard-coded cryptographic key in the firmware.","url":"https://insights.sbomify.com/CVE-2020-6979/"}
