DECT Standard Cypher (DSC) Encryption Bypass Vulnerability

DECT Standard Cypher (DSC) Encryption Standard is prone to an encryption-bypass vulnerability that allows attackers to recover the secret key.

Attackers can exploit this issue to overcome the DSC encryption algorithm and then read encrypted data sent from a wireless device to the base station. This may allow attackers to obtain potentially sensitive information; other attacks are also possible.
