{"cve":"CVE-2022-31482","nvd":{"published":"2022-06-06T17:15:11.210","modified":"2026-06-17T04:45:31.967","status":"Modified","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-120"],"references":["https://www.corporate.carrier.com/product-security/advisories-resources/","https://www.corporate.carrier.com/product-security/advisories-resources/"],"products":["carrier:lenels2_lnl-4420_firmware","carrier:lenels2_lnl-x2210_firmware","carrier:lenels2_lnl-x2220_firmware","carrier:lenels2_lnl-x3300_firmware","carrier:lenels2_lnl-x4420_firmware","carrier:lenels2_s2-lp-1501_firmware","carrier:lenels2_s2-lp-1502_firmware","carrier:lenels2_s2-lp-2500_firmware","carrier:lenels2_s2-lp-4502_firmware","hidglobal:ep4502_firmware","hidglobal:lp1501_firmware","hidglobal:lp1502_firmware","hidglobal:lp2500_firmware","hidglobal:lp4502_firmware"],"source":"nvd","synced_at":"2026-10-19T21:32:39.174919249+00:00"},"epss":{"cve":"CVE-2022-31482","score":0.01064,"percentile":0.64693,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
