CVE-2021-37444

Estado: ModificadaAlta (8.8)—

NCH IVM Attendant v5.12 and earlier suffers from a directory traversal weakness upon uploading plugins in a ZIP archive. This can lead to code execution if a ZIP element's pathname is set to a Windows startup folder, a file for the inbuilt Out-Going Message function, or a file for the the inbuilt Autodial function.
