CVSS v3.1 Overall Score: 2.4      

Analysis

Impacted version

An ACL entry on the SES Evolution agent directory that contains the agent logs displayed in the GUI allows interactive users to read data, which could allow access to information reserved to administrators, in case agent self-protection has been previously deactivated.

  • SES 2.0.0 to 2.4.2

Workaround solution

Solution

The vulnerability can be mitigated by disabling maintenance mode and challenges on SES Evolution agents, and preventing non-administrator users from booting in safe mode in the system configuration, so that the agent self-protection cannot be deactivated.

The 2.4.3 update fixes this vulnerability.
