This script removes the vulnerable 7-zip.chm file from known installation directories of 7-Zip, effectively mitigating CVE-2022-29072.
🔍 How it works:
The script defines the possible installation paths for 7-Zip.
It checks if the 7-zip.chm help file exists in those directories, which is known to be exploitable.
If found, the script safely removes the file, ensuring the vulnerability is neutralized. If the file or directory doesn’t exist, it informs the user.
