CVE 描述
Crux Agent from 1.9.0 before 2.0.3 uses the full SKA bilocation key as the WireGuard preshared key. When a peering session negotiates use of SHA-512, the key produced is 64 bytes instead of the 32 bytes WireGuard requires. The agent does not validate this size; instead it attempts to use the `wg set` command to update the live tunnel, and write the invalid key to the WireGuard configuration file. The update fails, so the live tunnel keeps using its previous preshared key until the tunnel is shut down. The tunnel will fail to start when restarted.
For a peer which has never successfully negotiated a 32-byte bilocation key in a Crux C2 organization which has the "Enforce SKA Use" setting turned off, no preshared key will be set for the tunnel. Therefore, an attacker who is able to intercept and store the peer's traffic, and has access (or will have access) to a cryptographically relevant quantum computer, will be able to decrypt the tunnel.

| 弱点名称 | 来源 | |
|---|---|---|
| Unchecked Return Value The product does not check the return value from a method or function. |
||
| Missing Cryptographic Step The product does not implement a required step in a cryptographic algorithm, resulting in weaker encryption than advertised by the algorithm. |
||
| Unexpected Status Code or Return Value The product does not properly check when a function or operation returns a value that is legitimate for the function, but is not expected by the product. |
