AlmaLinux 9 : subscription-manager (ALSA-2023:4708)

high Nessus Plugin ID 180078

Synopsis

The remote AlmaLinux host is missing a security update.

Description

The remote AlmaLinux 9 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2023:4708 advisory.

 - 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. (CVE-2023-3899)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
