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-2021-25846 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-2021-25846/ (Markdown: https://insights.sbomify.com/CVE-2021-25846/index.md)","id":"CVE-2021-25846","markdown":"https://insights.sbomify.com/CVE-2021-25846/index.md","name":"CVE-2021-25846","record":{"aliases":["GHSA-g8ph-56pg-h88p"],"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":"Attackers can cause denial of service in Moxa IP cameras by sending crafted LLDP packets that trigger a negative integer overflow in memory copy operations.","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":"Improper validation of the ChassisID TLV in userdisk/vport_lldpd in Moxa Camera VPort 06EC-2V Series, version 1.1, allows attackers to cause a denial of service due to a negative number passed to the memcpy function 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-2021-25846","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":"Information disclosure in n/a","id":"CVE-2021-25847"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2021-25845"},"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-2021-25849","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":"Attackers can cause denial of service in Moxa IP cameras by sending crafted LLDP packets that trigger a negative integer overflow in memory copy operations.","url":"https://insights.sbomify.com/CVE-2021-25846/"}
