Hard-Coded ECDSA Key Vulnerability in Tenda 4G03 Pro

Impact Analysis

The vulnerability allows remote attackers to exploit the hard-coded cryptographic key, potentially compromising the confidentiality of communications or data protected by this key. Since the key is fixed and known, attackers may be able to decrypt sensitive information or impersonate the device, leading to partial loss of confidentiality.
