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-2022-31482 in the wild and no public exploit code.\n\nAffected product: HID Mercury EP4502. 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-2022-31482/ (Markdown: https://insights.sbomify.com/CVE-2022-31482/index.md)","id":"CVE-2022-31482","markdown":"https://insights.sbomify.com/CVE-2022-31482/index.md","name":"CVE-2022-31482","record":{"aliases":["GHSA-4qf2-7m52-qfp8"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"HID Mercury controller","requires_auth":"none","summary":"Unauthenticated attackers can cause denial of service on HID Mercury controllers via buffer overflow in HTTP requests.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Carrier","cpe":[{"product":"lenels2_lnl-4420_firmware","vendor":"carrier"},{"product":"lenels2_lnl-x2210_firmware","vendor":"carrier"},{"product":"lenels2_lnl-x2220_firmware","vendor":"carrier"},{"product":"lenels2_lnl-x3300_firmware","vendor":"carrier"},{"product":"lenels2_lnl-x4420_firmware","vendor":"carrier"},{"product":"lenels2_s2-lp-1501_firmware","vendor":"carrier"},{"product":"lenels2_s2-lp-1502_firmware","vendor":"carrier"},{"product":"lenels2_s2-lp-2500_firmware","vendor":"carrier"},{"product":"lenels2_s2-lp-4502_firmware","vendor":"carrier"},{"product":"ep4502_firmware","vendor":"hidglobal"},{"product":"lp1501_firmware","vendor":"hidglobal"},{"product":"lp1502_firmware","vendor":"hidglobal"},{"product":"lp2500_firmware","vendor":"hidglobal"},{"product":"lp4502_firmware","vendor":"hidglobal"}],"cvss":{"score":7.5,"severity":"high","source":"cna","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-120","name":"Buffer Copy without Checking Size of Input"}],"description":"An unauthenticated attacker can send a specially crafted unauthenticated HTTP request to the device that can overflow a buffer. This vulnerability impacts products based on HID Mercury Intelligent Controllers LP1501, LP1502, LP2500, LP4502, and EP4502 which contain firmware versions prior to 1.29. The overflowed data leads to segmentation fault and ultimately a denial-of-service condition, causing the device to reboot. The impact of this vulnerability is that an unauthenticated attacker could leverage this flaw to cause the target device to become unresponsive. An attacker could automate this attack to achieve persistent DoS, effectively rendering the target controller useless.","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":"Denial-of-Service via internal structure overflow","id":"CVE-2022-31482","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Arbitrary file write via authenticated OSDP file upload","id":"CVE-2022-31483"},"packages":[],"prev":{"headline":"Remote Code Execution via buffer overflow in firmware update process","id":"CVE-2022-31481"},"products":["EP4502","LNL-4420","LNL-X2210","LNL-X2220","LNL-X3300","LNL-X4420","LP1501","LP1502","LP2500","LP4502","S2-LP-1501","S2-LP-1502","S2-LP-2500","S2-LP-4502"],"published":"2022-06-06","related":[{"cvss_score":10,"headline":"Remote Code Execution via buffer overflow in firmware update process","id":"CVE-2022-31481","kev_date_added":null,"published":"2022-06-06"},{"cvss_score":9.6,"headline":"Remote Code Execution via command injection of the hostname","id":"CVE-2022-31479","kev_date_added":null,"published":"2022-06-06"},{"cvss_score":9.1,"headline":"Arbitrary file write via authenticated OSDP file upload","id":"CVE-2022-31483","kev_date_added":null,"published":"2022-06-06"},{"cvss_score":8.8,"headline":"Command injection via Advanced Networking route add functionality","id":"CVE-2022-31486","kev_date_added":null,"published":"2022-06-06"},{"cvss_score":7.5,"headline":"Unauthenticated Firmware Upload and Arbitrary Reboot","id":"CVE-2022-31480","kev_date_added":null,"published":"2022-06-06"},{"cvss_score":7.5,"headline":"User Account Deletion Unauthenticated","id":"CVE-2022-31484","kev_date_added":null,"published":"2022-06-06"}],"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":"2024-09-17","vendors":["HID Mercury","LenelS2"]},"summary":"Unauthenticated attackers can cause denial of service on HID Mercury controllers via buffer overflow in HTTP requests.","url":"https://insights.sbomify.com/CVE-2022-31482/"}
