An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-14511 and fix it if it is affected.\n\nWhat it is: CVE-2020-14511 is a critical memory corruption vulnerability in EDR-G902 and EDR-G903 Series Routers, published on 15 Jul 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-2020-14511 in the wild and no public exploit code.\n\nAffected product: EDR-G902 and EDR-G903 Series Routers. 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-2020-14511/ (Markdown: https://insights.sbomify.com/CVE-2020-14511/index.md)","id":"CVE-2020-14511","markdown":"https://insights.sbomify.com/CVE-2020-14511/index.md","name":"CVE-2020-14511","record":{"aliases":["GHSA-3pp4-hx37-v55w"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"EDR Series Router","requires_auth":"none","summary":"A stack-based buffer overflow in the router's web server allows attackers to execute arbitrary code or cause a denial of service via a crafted cookie.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"edr-g902-t_firmware","vendor":"moxa"},{"product":"edr-g902_firmware","vendor":"moxa"},{"product":"edr-g903-t_firmware","vendor":"moxa"},{"product":"edr-g903_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-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Malicious operation of the crafted web browser cookie may cause a stack-based buffer overflow in the system web server on the EDR-G902 and EDR-G903 Series Routers (versions prior to 5.4).","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":"Memory corruption in EDR-G902 and EDR-G903 Series Routers","id":"CVE-2020-14511","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"USE OF PASSWORD HASH WITH INSUFFICIENT COMPUTATIONAL EFFORT CWE-916","id":"CVE-2020-14512"},"packages":[],"prev":{"headline":"OFF-BY-ONE ERROR CWE-193","id":"CVE-2020-14510"},"products":["EDR-G902 and EDR-G903 Series Routers"],"published":"2020-07-15","related":[],"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":"A stack-based buffer overflow in the router's web server allows attackers to execute arbitrary code or cause a denial of service via a crafted cookie.","url":"https://insights.sbomify.com/CVE-2020-14511/"}
