Subject: Dameware Mini Remote Control Version 4.2 – Weak Key Agreement Scheme
Title: Dameware Mini Remote Control Version 4.2 – Weak Key Agreement Scheme
Versions: Dameware Mini Remote Control Version 4.2
Vulnerability: The latest version of Dameware’s Mini Remote Control System uses a weak key agreement scheme. The scheme consists of the sharing of pointers into a fixed key lookup table. Both the client and the server have access to a key lookup table (KLT) consisting of 1000 32-bit values. Prior to encrypting traffic the server sends to the client a series of 32-bit integers, call it the key index table (KIT). For the sake of description lets call the indices klt_idx[4], an array of 4 32-bit integers. The klt_idx are set as follows:
klt_idx[0] = KIT[100];
klt_idx[1] = KIT[4];
klt_idx[2] = 42;
klt_idx[3] = KIT[37];
The actual session key is then constructed as 4 32-bit integers, sk[4] as follows.
sk[0] = KLT[klt_idx[0]];
sk[1] = KLT[klt_idx[1]];
sk[2] = KLT[klt_idx[2]];
sk[3] = KLT[klt_idx[3]];
This of course produces 0-bits of security.
They proceed to correct the Electronic Code Book mode of encrypting other authentication packets using the above constructed key using Blowfish in cipher block chaining mode with an IV = 0.
