It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-12620 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-12620/ (Markdown: https://insights.sbomify.com/CVE-2020-12620/index.md)","id":"CVE-2020-12620","markdown":"https://insights.sbomify.com/CVE-2020-12620/index.md","name":"CVE-2020-12620","record":{"aliases":["GHSA-6m9c-h626-jp3r"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Pi-hole DNS server","requires_auth":"low_privilege","summary":"An attacker with write access to the DNS configuration file can inject shell commands to execute arbitrary code and escalate privileges.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pi-hole","vendor":"pi-hole"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Pi-hole 4.4 allows a user able to write to /etc/pihole/dns-servers.conf to escalate privileges through command injection (shell metacharacters after an IP address).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Command injection in n/a","id":"CVE-2020-12620","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Auth bypass in n/a","id":"CVE-2020-12621"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2020-12619"},"products":["n/a"],"published":"2020-07-30","related":[{"cvss_score":9.1,"headline":"Pi-Hole AdminLTE Remote Code Execution","id":"CVE-2020-8816","kev_date_added":"2021-12-10","published":"2020-05-29"},{"cvss_score":9,"headline":"Pi-Hole AdminLTE Whitelist (now 'Web Allowlist') Remote Command Execution","id":"CVE-2025-34087","kev_date_added":null,"published":"2025-07-03"},{"cvss_score":8.8,"headline":"Pi-hole: Local privilege escalation from `pihole` user to root via `/etc/pihole/logrotate`","id":"CVE-2026-50130","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":8.8,"headline":"File upload in n/a","id":"CVE-2020-11108","kev_date_added":null,"published":"2020-05-11"},{"cvss_score":8.8,"headline":"Pi-Hole 4.3 allows Command Injection.","id":"CVE-2019-13051","kev_date_added":null,"published":"2019-10-09"},{"cvss_score":8.6,"headline":"Pi-hole Blind Server-Side Request Forgery (SSRF) vulnerability can lead to Remote Code Execution (RCE)","id":"CVE-2024-34361","kev_date_added":null,"published":"2024-07-05"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"An attacker with write access to the DNS configuration file can inject shell commands to execute arbitrary code and escalate privileges.","url":"https://insights.sbomify.com/CVE-2020-12620/"}
