FAQ
How do I get the update for Microsoft HPC Pack?
If you do not have automatic updates enabled you need to manually update your extension. See Update Network Watcher extension to the latest version for update instructions. Customers who have automatic updates enabled do not need to take any further action.
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, privileges required is high (PR:H). What does that mean for this vulnerability?
To successfully exploit this vulnerability, an attacker must be a Contributor or Owner in the target environment to perform actions restricted from average users.
