CVE-2023-21802: Windows Media Remote Code Execution Vulnerability

**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.

CVE-2023-21801: Microsoft PostScript Printer Driver Remote Code Execution Vulnerability

**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. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.

CVE-2023-21805: Windows MSHTML Platform Remote Code Execution Vulnerability

**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.

CVE-2023-21808: .NET and Visual Studio Remote Code Execution Vulnerability

**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. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.

CVE-2023-21799: Microsoft WDAC OLE DB provider for SQL Server Remote Code Execution Vulnerability

**How could an attacker exploit this vulnerability?** An attacker could exploit the vulnerability by tricking an authenticated user into attempting to connect to a malicious SQL server via OLEDB, which could result in the server receiving a malicious networking packet. This could allow the attacker to execute code remotely on the client.

CVE-2023-21803: Windows iSCSI Discovery Service Remote Code Execution Vulnerability

The following mitigating factors may be helpful in your situation: By default the iSCSI Initiator client application is disabled, in this state an attacker cannot exploit this vulnerability. For a system to be vulnerable, the iSCSI Initiator client application would need to be enabled.
