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. Successful exploitation may allow unauthorized disclosure of sensitive information, including administrative credentials.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
