An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-6991 and fix it if it is affected.\n\nWhat it is: CVE-2020-6991 is a critical 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-2020-6991 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-2020-6991/ (Markdown: https://insights.sbomify.com/CVE-2020-6991/index.md)","id":"CVE-2020-6991","markdown":"https://insights.sbomify.com/CVE-2020-6991/index.md","name":"CVE-2020-6991","record":{"aliases":["GHSA-hxmj-c6q3-rm4g"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Ethernet Switch","requires_auth":"none","summary":"Weak password requirements in Moxa EDS-G516E firmware allow attackers to gain unauthorized access via brute force attacks.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"eds-510e_firmware","vendor":"moxa"},{"product":"eds-g516e_firmware","vendor":"moxa"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-521","name":"Weak Password Requirements"}],"description":"In Moxa EDS-G516E Series firmware, Version 5.2 or lower, weak password requirements may allow an attacker to gain access using brute force.","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":"Weak cryptography in Moxa EDS-G516E Series firmware, Version 5.2 or lower","id":"CVE-2020-6991","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in GE Digital CIMPLICITY","id":"CVE-2020-6992"},"packages":[],"prev":{"headline":"Hardcoded credentials 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-2020-6990"},"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":"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":"Hardcoded credentials in Moxa EDS-G516E Series firmware, Version 5.2 or lower","id":"CVE-2020-6979","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":"Weak password requirements in Moxa EDS-G516E firmware allow attackers to gain unauthorized access via brute force attacks.","url":"https://insights.sbomify.com/CVE-2020-6991/"}
