Описание
A script injection vulnerability was identified in the Tuned package. The instance_create() D-Bus function can be called by locally logged-in users without authentication. This flaw allows a local non-privileged user to execute a D-Bus call with script_pre or script_post options that permit arbitrary scripts with their absolute paths to be passed. These user or attacker-controlled executable scripts or programs could then be executed by Tuned with root privileges that could allow attackers to local privilege escalation.
Отчет
The instance_create() D-Bus method has been added via upstream commit cddcd233 and was first part of version tag v2.23.0. Hence, versions of Tuned before 2.23.0 are unaffected. Also, note that the initial versions already contained support for the script option parameters and the instance_name parameter.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
