CVE-2025-34087: Pi-Hole AdminLTE Whitelist (now 'Web Allowlist') Remote Command Execution

Noroxi assessment

Priority: Plan (action score 40/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Because a ready-made attack tool exists, priority is at least “Plan”.
  • Probability of exploitation in the next 30 days: 6.8% (FIRST EPSS); higher than 94% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.

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

An authenticated command injection vulnerability exists in Pi-hole versions up to 3.3. When adding a domain to the allowlist via the web interface, the domain parameter is not properly sanitized, allowing an attacker to append OS commands to the domain string. These commands are executed on the underlying operating system with the privileges of the Pi-hole service user. This behavior was present in the legacy AdminLTE interface and has since been patched in later versions.
