Unbound Vulnerability Allows Attackers to Manipulate Resolver Configuration
CVE-2024-1488
Key Information:
Summary
A security vulnerability has been identified in Unbound, primarily stemming from incorrect default permissions settings. This flaw allows any process outside the designated unbound group to alter the unbound runtime configuration. If an attacker can connect to the localhost on port 8953, they gain the ability to modify the configuration of the unbound service. Such manipulation can lead to unauthorized tracking of all queries dispatched from the local resolver and may also disrupt the resolution process entirely, posing significant risks to system integrity and data confidentiality.
