In contrast to the regular file download via CmpFileTransfer, no filtering of certain file types is performed here. As a result, the integrity of the CODESYS control runtime system may be compromised by the files loaded onto the controller.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-552"],"references":["https://cert.vde.com/en/advisories/VDE-2023-019/","https://cert.vde.com/en/advisories/VDE-2023-019/"],"products":["codesys:control_for_beaglebone_sl","codesys:control_for_empc-a\\/imx6_sl","codesys:control_for_iot2000_sl","codesys:control_for_linux_sl","codesys:control_for_pfc100_sl","codesys:control_for_pfc200_sl","codesys:control_for_plcnext_sl","codesys:control_for_raspberry_pi_sl","codesys:control_for_wago_touch_panels_600_sl","codesys:control_rte_sl","codesys:control_rte_sl_\\(for_beckhoff_cx\\)","codesys:control_runtime_system_toolkit","codesys:control_win_sl","codesys:development_system","codesys:hmi","codesys:safety_sil2"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-37551","score":0.00498,"percentile":0.42693,"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).
