CVE-2023-21808

FAQ

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.

According to the CVSS metrics, there are multiple scores. Why does the CVE have different scores and different severities for different products?

There are different scores depending on the product due to the way symbols are read and parsed. Visual Studio has the ability to automatically query symbol servers while .NET only uses symbols present on the disk, requiring the user to manually query the symbol.
