CVE-2024-52336
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk20th percentile - higher than 20% of all known CVEs
Summary
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, allowing a non-privileged user to pass arbitrary scripts or programs via `script_pre` or `script_post` options, which are then executed by Tuned with root privileges, enabling privilege escalation.
Risk Assessment
The risk is that a local unprivileged attacker can gain full control over the system by executing arbitrary code with root privileges, leading to privilege escalation and potential compromise of the entire system.
Recommendation
Immediately update the Tuned package to a version that fixes this vulnerability and restrict access to the D-Bus interface for unprivileged users through appropriate security policies.
Other vulnerabilities in Tuned
Original NVD description (English source)
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.
