CAPEC の説明
An attacker, with control of a Cellular Rogue Base Station or through cooperation with a Malicious Mobile Network Operator can force the mobile device (e.g., the retransmission device) to use no encryption (A5/0 mode) or to use easily breakable encryption (A5/1 or A5/2 mode).
CAPEC の情報
前提条件
Cellular devices that allow negotiating security modes to facilitate backwards compatibility and roaming on legacy networks.必要なスキル
Adversaries can purchase and implement rogue BTS stations at a cost effective rate, and can push a mobile device to downgrade to a non-secure cellular protocol like 2G over GSM or CDMA.緩和策
Use of hardened baseband firmware on retransmission device to detect and prevent the use of weak cellular encryption.Monitor cellular RF interface to detect the usage of weaker-than-expected cellular encryption.

CWE-757 |
Selection of Less-Secure Algorithm During Negotiation A protocol or its implementation supports interaction between multiple actors and allows those actors to negotiate which algorithm should be used in a protection mechanism such as encryption or authentication, but it does not select the strongest algorithm that is available to both parties. |
