Title
TLS Private Key Accessible to External Parties
Summary
A CWE-552 "Files or Directories Accessible to External Parties” in the web interface of the Tyan S5552 BMC version 3.00 allows an unauthenticated remote attacker to retrieve the private key of the TLS certificate in use by the BMC via forced browsing. This can then be abused to perform Man-in-the-Middle (MitM) attacks against victims that access the web interface through HTTPS.
