It supports three security modes: Plain, Legacy Encryption, and New Encryption. In Legacy Encryption mode, traffic is encrypted via the Tiny Encryption Algorithm (TEA) block-cipher in ECB mode. This mode of operation does not offer message integrity and offers reduced confidentiality above the block level, as demonstrated by an ECB Penguin attack against any block ciphers.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-327","CWE-345"],"references":["https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation","https://www.cisa.gov/uscert/ics/advisories/icsa-22-179-05","https://www.forescout.com/blog/","https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation","https://www.cisa.gov/uscert/ics/advisories/icsa-22-179-05"],"products":["motorolasolutions:mdlc"],"source":"nvd","synced_at":"2026-10-19T21:33:44.859608815+00:00"},"epss":{"cve":"CVE-2022-30273","score":0.00441,"percentile":0.38319,"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).
