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-2021-25849 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-2021-25849/ (Markdown: https://insights.sbomify.com/CVE-2021-25849/index.md)","id":"CVE-2021-25849","markdown":"https://insights.sbomify.com/CVE-2021-25849/index.md","name":"CVE-2021-25849","record":{"aliases":["GHSA-vwhr-cxjh-7vpw"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Moxa IP Camera","requires_auth":"none","summary":"An integer underflow in Moxa IP Cameras allows remote attackers to cause a denial of service via crafted LLDP packets.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"vport_06ec-2v26m_firmware","vendor":"moxa"},{"product":"vport_06ec-2v36m-ct-t_firmware","vendor":"moxa"},{"product":"vport_06ec-2v36m-ct_firmware","vendor":"moxa"},{"product":"vport_06ec-2v36m-t_firmware","vendor":"moxa"},{"product":"vport_06ec-2v42m-ct-t_firmware","vendor":"moxa"},{"product":"vport_06ec-2v42m-ct_firmware","vendor":"moxa"},{"product":"vport_06ec-2v42m-t_firmware","vendor":"moxa"},{"product":"vport_06ec-2v42m_firmware","vendor":"moxa"},{"product":"vport_06ec-2v60m-ct-t_firmware","vendor":"moxa"},{"product":"vport_06ec-2v60m-ct_firmware","vendor":"moxa"},{"product":"vport_06ec-2v60m-t_firmware","vendor":"moxa"},{"product":"vport_06ec-2v60m_firmware","vendor":"moxa"},{"product":"vport_06ec-2v80m-ct-t_firmware","vendor":"moxa"},{"product":"vport_06ec-2v80m-ct_firmware","vendor":"moxa"},{"product":"vport_06ec-2v80m-t_firmware","vendor":"moxa"},{"product":"vport_06ec-2v80m_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:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"}],"description":"An integer underflow was discovered in userdisk/vport_lldpd in Moxa Camera VPort 06EC-2V Series, version 1.1, improper validation of the PortID TLV leads to Denial of Service via a crafted lldp packet.","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":"Integer overflow in n/a","id":"CVE-2021-25849","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Path traversal in n/a","id":"CVE-2021-25856"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2021-25848"},"products":["n/a"],"published":"2021-05-10","related":[{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2021-25847","kev_date_added":null,"published":"2021-05-10"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2021-25848","kev_date_added":null,"published":"2021-05-10"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2021-25845","kev_date_added":null,"published":"2021-05-10"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2021-25846","kev_date_added":null,"published":"2021-05-10"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"An integer underflow in Moxa IP Cameras allows remote attackers to cause a denial of service via crafted LLDP packets.","url":"https://insights.sbomify.com/CVE-2021-25849/"}
