The zero-day vulnerability in 7- Zip software, tracked as CVE-2022-29072 is marked as disputed by the National Vulnerability Database(NVD), and sparked discussions over its consequences. This started when a researcher published a proof-of-concept (POC) for this vulnerability and stated that it allowed remote privilege escalation. However, other well-known researchers, such as those from Google’s Project Zero, have indicated that this security flaw would allow the execution of arbitrary code via 7-Zip while opening a file with the.7z extension.

The impact of this vulnerability remains uncertain and due to the non-availability of the patch and a proof-of-concept being widely available, The Hive pro Threat research team recommends temporarily resolving this issue by deleting the Help file. The following are the steps to do this:
1. Open the 7-Zip installation directory or folder on the system
2. Locate the file 7-Zip.chm; this is the help file
3. Right-click on the file and select the Delete context menu option, to remove it from the system.
