Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
Massimiliano Montoro has reported a security issue in Microsoft Windows, which can be exploited by malicious people to conduct MitM (Man-in-the-Middle) attacks.

The problem is that the private key used for signing a terminal server's public key is hard-coded into the mstlsapi.dll library. This can be exploited to calculate a valid signature, which can be used for performing MitM attacks.

Successful exploitation requires that a malicious person is able to intercept traffic between the terminal client and terminal server.

NOTE: Functionality for exploiting this has reportedly been included in Cain & Abel 2.7.
