Vulnerability details

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.

MITRE ATT&CK Enterprise TechniquesAI

T1574.010 Services File Permissions Weakness Stealth
Adversaries may execute their own malicious payloads by hijacking the binaries used by services.
T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
T1557 Adversary-in-the-Middle Credential Access
Adversaries may attempt to position themselves between two or more networked devices using an adversary-in-the-middle (AiTM) technique to support follow-on behaviors such as [Network Sniffing](https://attack.
Why these techniques?

Incorrect default permissions on Unbound's control interface (unix socket or localhost port) allow unprivileged local processes to reconfigure the DNS resolver (T1044), enabling exploitation for privilege escalation (T1068) and adversary-in-the-middle attacks on DNS queries by altering forwarders (T1557).

addresses: CWE-276

Establishes requirements for appropriate default permissions on system resources as part of configuration management.

addresses: CWE-276

Baseline establishment and updates on install/upgrade ensure correct default permissions rather than insecure ones.

addresses: CWE-276

Requiring the most restrictive settings instead of defaults prevents incorrect default permissions on resources.

addresses: CWE-276

Requires documented processes that include setting and maintaining correct default permissions for configuration items.

addresses: CWE-276

Requires addressing secure default permissions in physical and environmental protection controls.

addresses: CWE-276

Tailoring explicitly overrides or scopes default permission assignments in the baseline to match the system's actual risk and operational needs.
