Ekahau Real-Time Location System suffers from RC4 cipher stream reuse and weak key derivation flaws The message payload of the affected solution is always encrypted using the same RC4 cipher stream When combining two encrypted messages with an XOR operation, the cipher stream will cancel out With this, an attacker is able to recover the bitwise ...
