They utilize the CMPLink/TCP protocol (configurable on ports 1024-65534 on either TCP or UDP) for a wide variety of engineering purposes such as starting and stopping the PLC, downloading and uploading projects, and changing configuration settings. This protocol does not have any authentication features, allowing any attacker capable of communicating with the port in question to invoke (a subset of) desired functionality.","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:H/A:H","score":9.1},"cwes":["CWE-306"],"references":["https://www.cisa.gov/uscert/ics/advisories/icsa-22-172-02","https://www.forescout.com/blog/","https://www.cisa.gov/uscert/ics/advisories/icsa-22-172-02","https://www.forescout.com/blog/"],"products":["jtekt:nano_10gx_tuc-1157_firmware","jtekt:nano_cpu_tuc-6941_firmware","jtekt:pc10b-p_tcc-6373_firmware","jtekt:pc10b_tcc-1021_firmware","jtekt:pc10e_tcc-4737_firmware","jtekt:pc10el_tcc-4747_firmware","jtekt:pc10g-cpu_tcc-6353_firmware","jtekt:pc10ge_tcc-6464_firmware","jtekt:pc10p-dp-io_tcc-6752_firmware","jtekt:pc10p-dp_tcc-6726_firmware","jtekt:pc10p_tcc-6372_firmware","jtekt:pc10pe-1616p_tcc-1102_firmware","jtekt:pc10pe_tcc-1101_firmware","jtekt:pc3jx-d_tcc-6902_firmware","jtekt:pc3jx_tcc-6901_firmware","jtekt:pcdl_tkc-6688_firmware","jtekt:plus_cpu_tcc-6740_firmware"],"source":"nvd","synced_at":"2026-10-19T21:33:44.859608815+00:00"},"epss":{"cve":"CVE-2022-29951","score":0.01324,"percentile":0.70921,"date":"2026-11-01"},"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).
