Description

This security bulletin contains information about 4 vulnerabilities.


1) Improper Authorization (CVE-ID: CVE-2023-4456)

CWE-ID: CWE-285 - Improper Authorization

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


The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to LokiStack component uses a regular token as key for caching. A remote user with a key valid for one action can execute other actions as long as the authorization allowing the original action is still cached.


2) Incorrect authorization (CVE-ID: CVE-2023-3899)

CWE-ID: CWE-863 - Incorrect Authorization

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


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to incorrect authorization caused by D-Bus interface com.redhat.RHSM1 that exposes a significant number of methods to all users. A local user can abuse the com.redhat.RHSM1.Config.SetAll() method to change the state of the registration and escalate privileges on the system.


3) Improper Authentication (CVE-ID: CVE-2023-32360)

CWE-ID: CWE-287 - Improper Authentication

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


The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to missing authentication in CUPS. A remote attacker can access recently printed documents.


4) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-34969)

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

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


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to an error in the dbus-daemon when sending a reply message from the "bus driver". If a local privileged user (e.g. root) is using the org.freedesktop.DBus.Monitoring interface to monitor message bus traffic, another unprivileged user with the ability to connect to the same dbus-daemon can force the service to send an unreplyable message and perform a denial of service (DoS) attack.
