CVE-2019-3750

Estado: ModificadaMedia (5.5)—

Dell Command Update versions prior to 3.1 contain an Arbitrary File Deletion Vulnerability. A local authenticated malicious user with low privileges potentially could exploit this vulnerability to delete arbitrary files by creating a symlink from the "Temp\IC\ICDebugLog.txt" to any targeted file. This issue occurs because of insecure handling of Temp directory permissions that were set incorrectly.
