Summary
Vim is an open source, command line text editor. From 9.1.1784 until 9.2.0678, when the bundled zip plugin autoload/zip.vim falls back to PowerShell to browse, read, extract, update or delete entries in a zip archive, it builds the PowerShell command by inserting archive entry names that are quoted only for the shell, not for PowerShell.
A crafted entry name can break out of the intended string context and cause PowerShell to execute arbitrary commands with the privileges of the user running Vim, triggered by opening, viewing or extracting the archive. This vulnerability is fixed in 9.2.0678.
A security vulnerability exists in the Vim text editor. If a user opens a specially crafted ZIP file in Vim, it can trick the application into running hidden, harmful commands on their computer.
This specific issue is only triggered if Vim relies on PowerShell to open the ZIP file. This vulnerability was introduced in Vim version 9.1.1784.
Because Red Hat products do not ship this version, they are unaffected. Red Hat severity: Moderate — CVSS 5.8 (CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:L/I:H/A:L).
Weakness: CWE-78. Red Hat lists Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat OpenShift Container Platform 4 as not affected.
