CVE-2024-1488: Unbound: unrestricted reconfiguration enabled to anyone that may lead to local privilege escalation

HighCVSS 7.3 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 29/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.32% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: python3-unbound (AlmaLinux:8) 1.16.2-5.8.el8_10, 1.16.2-5.el8_9.6; unbound (AlmaLinux:8) 1.16.2-5.el8_9.6, 1.16.2-5.8.el8_10; unbound-devel (AlmaLinux:8) 1.16.2-5.el8_9.6, 1.16.2-5.8.el8_10.

Low priority for now. Upgrade to python3-unbound (AlmaLinux:8) 1.16.2-5.8.el8_10, 1.16.2-5.el8_9.6; unbound (AlmaLinux:8) 1.16.2-5.el8_9.6, 1.16.2-5.8.el8_10; unbound-devel (AlmaLinux:8) 1.16.2-5.el8_9.6, 1.16.2-5.8.el8_10 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside the unbound group to modify the unbound runtime configuration. If a process can connect over localhost to port 8953, it can alter the configuration of unbound.service. This flaw allows an unprivileged attacker to manipulate a running instance, potentially altering forwarders, allowing them to track all queries forwarded by the local resolver, and, in some cases, disrupting resolving altogether.
