CVE-2023-3899

Subscription-manager: inadequate authorization of com.redhat.rhsm1 d-bus interface allows local users to modify configuration

Published: Aug 23, 2023Updated: Nov 21, 2024 Sources: CVE List NVD BDUCWE-285

Description

A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization. The D-Bus interface com.redhat.RHSM1 exposes a significant number of methods to all users that could change the state of the registration. By using the com.redhat.RHSM1.Config.SetAll() method, a low-privileged local user could tamper with the state of the registration, by unregistering the system or by changing the current entitlements. This flaw allows an attacker to set arbitrary configuration directives for /etc/rhsm/rhsm.conf, which can be abused to cause a local privilege escalation to an unconfined root.
