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-2019-6557 in the wild and no public exploit code.\n\nAffected product: ICS-CERT Moxa IKS, EDS. 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-2019-6557/ (Markdown: https://insights.sbomify.com/CVE-2019-6557/index.md)","id":"CVE-2019-6557","markdown":"https://insights.sbomify.com/CVE-2019-6557/index.md","name":"CVE-2019-6557","record":{"aliases":["GHSA-cgrr-xgfh-rgv2"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Moxa industrial switch","requires_auth":"none","summary":"Buffer overflows in Moxa IKS and EDS devices allow remote attackers to execute arbitrary code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"eds-405a_firmware","vendor":"moxa"},{"product":"eds-408a_firmware","vendor":"moxa"},{"product":"eds-510a_firmware","vendor":"moxa"},{"product":"iks-g6824a_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-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Several buffer overflow vulnerabilities have been identified in Moxa IKS and EDS, which may allow remote code execution.","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 Moxa IKS, EDS","id":"CVE-2019-6557","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Auth bypass in Auto-Maskin RP210E Versions 3.7 and prior DCU210E Versions 3.7 and prior and Marine Observer Pro (Android App)","id":"CVE-2019-6558"},"packages":[],"prev":{"headline":"Use after free in CX-Programmer within CX-One","id":"CVE-2019-6556"},"products":["Moxa IKS, EDS"],"published":"2019-03-05","related":[{"cvss_score":9.8,"headline":"Information disclosure in IKS, EDS","id":"CVE-2019-6526","kev_date_added":null,"published":"2019-04-12"},{"cvss_score":9.8,"headline":"Auth bypass in Moxa IKS, EDS","id":"CVE-2019-6524","kev_date_added":null,"published":"2019-03-05"},{"cvss_score":9.8,"headline":"Weak cryptography in Moxa IKS, EDS","id":"CVE-2019-6563","kev_date_added":null,"published":"2019-03-05"},{"cvss_score":9.1,"headline":"Information disclosure in Moxa IKS, EDS","id":"CVE-2019-6522","kev_date_added":null,"published":"2019-03-05"},{"cvss_score":8.8,"headline":"Cross-site request forgery in Moxa IKS, EDS","id":"CVE-2019-6561","kev_date_added":null,"published":"2019-03-05"},{"cvss_score":8.5,"headline":"Security feature bypass in n/a","id":"CVE-2015-6464","kev_date_added":null,"published":"2015-09-11"}],"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":["ICS-CERT"]},"summary":"Buffer overflows in Moxa IKS and EDS devices allow remote attackers to execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2019-6557/"}
