Details:  
The vulnerability details are as follows:

*  Buffer overflow vulnerability (CVE-2018-1205)

*  Improper Restriction of Excessive Authentication Attempts Vulnerability  (CVE-2018-1237) 
Dell EMC ScaleIO versions prior to 2.5, contain improper restriction of excessive authentication attempts on the Light installation Agent (LIA). This component is deployed on every server in the ScaleIO cluster and is used for central management of ScaleIO nodes. A remote malicious user, having network access to LIA, could potentially exploit this vulnerability to launch brute force guessing of user names and passwords of user accounts on the LIA.
CVSSv3 Base Score: 5.9 (AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

*  Command injection vulnerability (CVE-2018-1238)
Dell EMC ScaleIO versions prior to 2.5, contain a command injection vulnerability in the Light Installation Agent (LIA). This component is used for central management of ScaleIO deployment and uses shell commands for certain actions. A remote malicious user, with network access to LIA and knowledge of the LIA administrative password, could potentially exploit this vulnerability to run arbitrary commands as root on the systems where LIAs are installed.
