Any changes made to the header would just cause the request to be sent to a completely different Domain/IP address. This is due to that the server implicitly trusts the Host header, and fails to validate or escape it properly. An attacker can use this input to redirect target users to a malicious domain/web page. This would result in expanding the potential to further attacks and malicious actions.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-116"],"references":["https://github.com/IthacaLabs/CompassPlus/tree/main/TranzWare%20Online%20FIMI_Version%204.2.19.4%2025_HHI","https://github.com/IthacaLabs/CompassPlus/tree/main/TranzWare%20Online%20FIMI_Version%204.2.19.4%2025_HHI"],"products":["compassplus:tranzware_online","compassplus:tranzware_online_financial_institution_maintenance_interface"],"source":"nvd","synced_at":"2026-10-19T21:28:04.509275555+00:00"},"epss":{"cve":"CVE-2021-43106","score":0.00683,"percentile":0.52543,"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).
