An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-3872 in the wild and no public exploit code.\n\nAffected product: Puppet Puppet Enterprise. 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-2011-3872/ (Markdown: https://insights.sbomify.com/CVE-2011-3872/index.md)","id":"CVE-2011-3872","markdown":"https://insights.sbomify.com/CVE-2011-3872/index.md","name":"CVE-2011-3872","record":{"aliases":["DEBIAN-CVE-2011-3872","DSA-2352-1","GHSA-494g-9grq-m629"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Puppet configuration management","requires_auth":"none","summary":"Remote attackers can spoof a Puppet master via MITM attacks due to improper certificate validation, compromising agent communications.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"puppet","vendor":"puppet"},{"product":"puppet_enterprise","vendor":"puppet"},{"product":"puppet","vendor":"puppetlabs"},{"product":"puppet_enterprise_users","vendor":"puppetlabs"}],"cvss":{"score":2.6,"severity":"low","source":"nvd","vector":"AV:N/AC:H/Au:N/C:N/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Puppet 2.6.x before 2.6.12 and 2.7.x before 2.7.6, and Puppet Enterprise (PE) Users 1.0, 1.1, and 1.2 before 1.2.4, when signing an agent certificate, adds the Puppet master's certdnsnames values to the X.509 Subject Alternative Name field of the certificate, which allows remote attackers to spoof a Puppet master via a man-in-the-middle (MITM) attack against an agent that uses an alternate DNS name for the master, aka \"AltNames Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2011-10-17","github_poc":1,"max_poc_stars":5,"metasploit":0,"nuclei":0,"refs":[{"date":"2011-10-17T01:26:34Z","kind":"github_poc","ref":"https://github.com/puppetlabs-toy-chest/puppetlabs-cve20113872","stars":5,"title":"Puppet Module to help fix and migrate a Puppet deployment (CVE-2011-3872)"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Security feature bypass in n/a","id":"CVE-2011-3872","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"puppet:puppet_enterprise","products":["puppet:puppet_enterprise"],"type":"security_feature_bypass","year":"2011"},"n_packages":0,"n_references":11,"next":{"headline":"Memory corruption in n/a","id":"CVE-2011-3873"},"packages":[],"prev":{"headline":"Puppet uses predictable filenames, allowing arbitrary file overwrite","id":"CVE-2011-3871"},"products":["n/a"],"published":"2011-10-27","related":[{"cvss_score":9.8,"headline":"Puppet Improper Access Control","id":"CVE-2016-2785","kev_date_added":null,"published":"2016-06-10"},{"cvss_score":8.8,"headline":"SQL injection in Puppet DB","id":"CVE-2021-27021","kev_date_added":null,"published":"2021-07-20"},{"cvss_score":8.8,"headline":"Privilege escalation in Puppet Enterprise and Puppet Agent","id":"CVE-2018-6513","kev_date_added":null,"published":"2018-06-11"},{"cvss_score":7.8,"headline":"Privilege escalation in Puppet Agent","id":"CVE-2018-6514","kev_date_added":null,"published":"2018-06-11"},{"cvss_score":7.8,"headline":"Code injection in Puppet Agent","id":"CVE-2018-6515","kev_date_added":null,"published":"2018-06-11"},{"cvss_score":7.5,"headline":"Puppet Improper Input Validation vulnerability","id":"CVE-2013-1655","kev_date_added":null,"published":"2013-03-20"},{"cvss_score":6.9,"headline":"Puppet Privilege Escallation","id":"CVE-2012-1053","kev_date_added":null,"published":"2012-05-29"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can spoof a Puppet master via MITM attacks due to improper certificate validation, compromising agent communications.","url":"https://insights.sbomify.com/CVE-2011-3872/"}
