Vulnerability Issues

Reference	Resolution
CVE-2023-4814 SB10395	Fixed an issue where Trellix DLP Endpoint - SaaS deleted empty folders outside the DLP logs folder when a junction point was added inside the DLP logs folder. This issue was fixed by removing the directory junction or symbolic link present in the logs folder before cleaning up older logs. This fix broke the link between the logs folder and folders outside the logs folder. As a result, folders placed outside the DLP logs folder remain safe. The program also keeps track of temp folders and prevents the creation of directory junctions or symbolic links. For more information about vulnerability and remediation, see SB10395.
