Description

This security bulletin contains information about 1 vulnerability.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-6195)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to an authorization bypass issue. A remote authenticated attacker on the local network can gain read-only access to higher-privileged information if 1) “LDAP Authentication Only with Local Authorization” mode is configured and used by XCC, and 2) a lesser privileged user logs into XCC within 1 minute of a higher privileged user logging out.
