Summary

A hardcoded cryptographic key management vulnerability exists in Archer C6 due to the use of a universal cryptographic key shared across devices. An attacker who obtains an encrypted configuration file or other protected credential data can recover plaintext credentials.

Risk Assessment

Successful exploitation may allow unauthorized disclosure of sensitive information, including administrative credentials, potentially leading to device compromise.

Recommendation

Update Archer C6 router firmware to a version that does not use a shared key. Protect configuration files and regularly change administrative passwords.
