CVE-2025-34087 is a critical-severity OS Command Injection (CWE-78) vulnerability in Pi-Hole Pi-Hole. Its CVSS base score is 9.0 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
An authenticated command injection vulnerability affects Pi-hole versions up to 3.3 in the legacy AdminLTE web interface. When a domain is added to the allowlist, the domain parameter is not sanitized, permitting an attacker to append operating system commands that execute with the privileges of the Pi-hole service user. The issue is tracked as CWE-78 and carries a CVSS 4.0 score of 9.0.
An attacker with a valid account on the web interface can supply a crafted domain string containing shell metacharacters. Successful exploitation grants arbitrary command execution on the underlying host, enabling full control over DNS filtering configuration and potential lateral movement or persistence within the network.
The vulnerability was addressed in the Pi-hole web interface release v4.0. Public references, including the Pulse Security advisory and the VulnCheck entry, recommend upgrading to a patched version and restricting administrative access to the web interface.
A Metasploit module for the flaw is publicly available, and the EPSS score has reached 0.7218.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
