#Security Vulnerability

**How could an attacker exploit this vulnerability?** In order to exploit this vulnerability the attacker is required to be a local user with a smart card or already logged on remotely through RDP to the remote machine. The authorized attacker could then exploit this Windows LSASS vulnerability by sending, from a user mode application, specially crafted malicious credentials directed at the Windows machine, which could lead to remote code execution.

**According to the CVSS, User Interaction is Required. What interaction would the user have to do?** This vulnerability requires that a user with an affected version of Windows access a malicious server. An attacker would have to host a specially crafted server share or website. An attacker would have no way to force users to visit this specially crafted server share or website, but would have to convince them to visit the server share or website, typically by way of an enticement in an email or chat message.

**According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the **Attack Vector** is **Local** and **User Interaction** is **Required**, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.

**I am running a supported version of Windows Server. Is my system vulnerable to this issue?** This vulnerability is only exploitable for systems that have the NFS role enabled. See NFS Overview for more information on this feature. More information on installing or uninstalling Roles or Role Services is available here.

**What privileges does an attacker require to exploit this vulnerability?** Exploiting this vulnerability requires an attacker to compromise admin credentials to the replication appliance, configuration server, or one of the VMs associated with the configuration server.

**Why is Attack Complexity marked as High for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to take additional actions prior to exploitation to prepare the target environment.

**According the CVSS score, privileges required is set to High. In this case, what does that mean?** To exploit this vulnerability, the attacker or targeted user would need specific elevated privileges. As is best practice, regular validation and audits of administrative groups should be conducted.
