CVE-2023-22743

Git for Windows is the Windows port of the revision control system Git. Prior to Git for Windows version 2.39.2, by carefully crafting DLL and putting into a subdirectory of a specific name living next to the Git for Windows installer, Windows can be tricked into side-loading said DLL. This potentially allows users with local write access to place malicious payloads in a location where automated upgrades might run the Git for Windows installer with elevation. Version 2.39.2 contains a patch for this issue. Some workarounds are available. Never leave untrusted files in the Downloads folder or its sub-folders before executing the Git for Windows installer, or move the installer into a different directory before executing it.

Summary
  • (es) Git para Windows es el puerto de Windows del sistema de control de revisiones Git. Antes de Git para Windows versión 2.39.2, al crear cuidadosamente la DLL y colocarla en un subdirectorio con un nombre específico junto al instalador de Git para Windows, se podía engañar a Windows para que cargara dicha DLL. Potencialmente, esto permite a los usuarios con acceso de escritura local colocar payloads maliciosos en una ubicación donde las actualizaciones automáticas podrían ejecutar el instalador de Git para Windows con elevación. La versión 2.39.2 contiene un parche para este problema. Algunos workarounds están disponibles. Nunca deje archivos que no sean de confianza en la carpeta Descargas o sus subcarpetas antes de ejecutar el instalador de Git para Windows, ni mueva el instalador a un directorio diferente antes de ejecutarlo.
