The camera reads configuration from QR code (including network settings). The static IP configuration from QR code is copied to the file /config/ip-static and after reboot data from this file is inserted into bash command (without any escaping). So bash injection is possible. Camera doesn't parse QR codes if it's already successfully configured. Camera is always rebooted after successful configuration via QR code.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":6.8},"cwes":["CWE-78"],"references":["https://dil4rd.medium.com/groundhog-day-in-iot-valley-or-5-cves-in-1-camera-7dc1d2864707","https://dil4rd.medium.com/groundhog-day-in-iot-valley-or-5-cves-in-1-camera-7dc1d2864707"],"products":["company:cs-c2shw_firmware"],"source":"nvd","synced_at":"2026-10-19T21:14:10.479542811+00:00"},"epss":{"cve":"CVE-2020-27542","score":0.01183,"percentile":0.67786,"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).
