7-Zip < 25.01

low Nessus Plugin ID 249179

Synopsis

The remote host is missing a security update.

Description

The version of 7-Zip installed on the remote host is prior to 25.01. It is, therefore, affected by a security bypass vulnerability. The code for handling symbolic links has been changed to provide greater security when extracting files from archives. Command line switch -snld20 can be used to bypass default security checks when creating symbolic links.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to 7-Zip version 25.01 or later.
