**Is the Preview Pane an attack vector for this vulnerability?** No, the Preview Pane is not an attack vector.

**According to the CVSS metric, the attack vector is local (AV:L). 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.

**According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability?** This vulnerability's attack is limited at the protocol level to a logically adjacent topology. This means it cannot simply be done across the internet, but instead needs something specific tied to the target. Good examples would include the same shared physical network (such as Bluetooth or IEEE 802.11), logical network (local IP subnet), or from within a secure or otherwise limited administrative domain (MPLS, secure VPN to an administrative network zone). This is common to many attacks that require man-in-the-middle type setups or that rely on initially gaining a foothold in another environment.

**How could an attacker exploit this vulnerability?** An unauthenticated attacker could send a specially crafted connection request to a RAS server, which could lead to remote code execution (RCE) on the RAS server machine.

**According to the CVSS metric, privileges required is high (PR:H). What privileges does an attacker require to exploit this vulnerability?** Successful exploitation of this vulnerability requires an attacker to compromise admin credentials to one of the VMs associated with the configuration server.

**According to the CVSS metric, privileges required is high (PR:H). What privileges does an attacker require to exploit this vulnerability?** Successful exploitation of this vulnerability requires an attacker to compromise admin credentials to one of the VMs associated with the configuration server.
