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 metric, user interaction is required (UI:R). What interaction would the user have to do?
Exploitation of this vulnerability requires that a user trigger the payload in the application.
