Nmap NSE scripts to check against exchange vulnerability (CVE-2022-41082).
NSE scripts check most popular exposed services on the Internet. It is basic script which checks if virtual patching works.

### Examples

Since, there is no patch currently - only workarounds are checked if host is vulnerable.

Simple Example:
```
nmap -sV -T4 -v --script=http-vuln-cve-2022 scanme.nmap.org
```

Faster run (large subnets):
```
nmap -p443 -T4 -v --script=http-vuln-cve-2022 10.0.0.0/16
```

## Sample Output

### Vulnerable
Vulnerable:
```
nmap -Pn -T4 -p443 --script=http-vuln-cve2022-41082.nse 127.0.0.1
