Date Discovered April 14, 2015
Description Microsoft Active Directory Federation Services is prone to an information-disclosure vulnerability.
An attacker can exploit this issue to gain access to sensitive information that may aid in further attacks.
- Microsoft Active Directory Federation Services 3.0
- Microsoft Windows Server 2012 R2
Block external access at the network boundary, unless external parties require service. Filter access to the affected computer at the network boundary if global access isn't required. Restricting access to only trusted computers and networks might greatly reduce the likelihood of exploits.
Deploy network intrusion detection systems to monitor network traffic for malicious activity. Deploy NIDS to monitor network traffic for
anomalous or suspicious activity. Monitor logs generated by NIDS and by the server itself for evidence of attacks against the server.
Permit privileged access for trusted individuals only.
Permitting access to vulnerable applications for trusted individuals only can reduce the risk of an exploit.
Updates are available. Please see the references or vendor advisory for more information.
