OS command injection in Tenda HG3 router version 2.0 allows authenticated remote attackers to execute arbitrary commands with device privileges via the 'countrystr' parameter in /boaform/formCountrystr endpoint. Public exploit code exists (CVSS 4.0 E:P modifier confirms POC availability), enabling authenticated attackers to fully compromise router confidentiality, integrity, and availability. EPSS data unavailable; not currently in CISA KEV catalog, suggesting exploitation may be targeted rather than widespread despite public POC.
