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.
AnalysisAI
A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside the unbound group to modify the unbound runtime configuration. Rated high severity (CVSS 7.3), this vulnerability is low attack complexity.
Technical ContextAI
This vulnerability is classified as Incorrect Default Permissions (CWE-276), which allows attackers to access resources due to overly permissive default settings. 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. Affected products include: Fedoraproject Unbound, Redhat Codeready Linux Builder, Redhat Codeready Linux Builder Eus, Redhat Codeready Linux Builder Eus For Power Little Endian, Redhat Codeready Linux Builder For Arm64.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Set restrictive default permissions, follow principle of least privilege, review defaults during deployment.
