CVE-2018-11064

Estado: ModificadaAlta (7.8)—

Dell EMC Unity OE versions 4.3.0.x and 4.3.1.x and UnityVSA OE versions 4.3.0.x and 4.3.1.x contains an Incorrect File Permissions vulnerability. A locally authenticated malicious user could potentially exploit this vulnerability to alter multiple library files in service tools that might result in arbitrary code execution with elevated privileges. No user file systems are directly affected by this vulnerability.
