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-2009-5147 in the wild and no public exploit code.\n\nAffected product: Ruby-Lang Ruby. 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-2009-5147/ (Markdown: https://insights.sbomify.com/CVE-2009-5147/index.md)","id":"CVE-2009-5147","markdown":"https://insights.sbomify.com/CVE-2009-5147/index.md","name":"CVE-2009-5147","record":{"aliases":["DLA-299-1","DLA-300-1","GHSA-mmq8-m72q-qgm4","UBUNTU-CVE-2009-5147"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby programming language","requires_auth":"none","summary":"Attackers can execute arbitrary code by exploiting tainted library names in Ruby's DL::dlopen function, requiring a patch to mitigate.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ruby","vendor":"ruby-lang"}],"cvss":{"score":7.3,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"DL::dlopen in Ruby 1.8, 1.9.0, 1.9.2, 1.9.3, 2.0.0 before patchlevel 648, and 2.1 before 2.1.8 opens libraries with tainted names.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2017-03-14","github_poc":2,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2017-03-14T09:04:14Z","kind":"github_poc","ref":"https://github.com/vpereira/CVE-2009-5147","stars":0,"title":"poc for CVE-2009-5147"},{"date":"2019-04-25T06:46:50Z","kind":"github_poc","ref":"https://github.com/zhangyongbo100/-Ruby-dl-handle.c-CVE-2009-5147-","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Code injection in n/a","id":"CVE-2009-5147","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ruby-lang:ruby","products":["ruby-lang:ruby"],"type":"code_injection","year":"2009"},"n_packages":0,"n_references":6,"next":{"headline":"Hardcoded credentials in n/a","id":"CVE-2009-5149"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2009-5146"},"products":["n/a"],"published":"2017-03-29","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2009-4124","kev_date_added":null,"published":"2009-12-11"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-28738","kev_date_added":null,"published":"2022-05-09"},{"cvss_score":9.8,"headline":"Weak cryptography in OpenSSL extension of Ruby (Git trunk)","id":"CVE-2011-4121","kev_date_added":null,"published":"2019-11-26"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2017-17790","kev_date_added":null,"published":"2017-12-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-11465","kev_date_added":null,"published":"2017-07-19"},{"cvss_score":9.8,"headline":"Memory corruption in Ruby","id":"CVE-2016-2336","kev_date_added":null,"published":"2017-01-06"},{"cvss_score":9.8,"headline":"Code injection in Ruby","id":"CVE-2016-2337","kev_date_added":null,"published":"2017-01-06"}],"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":"2024-08-07","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code by exploiting tainted library names in Ruby's DL::dlopen function, requiring a patch to mitigate.","url":"https://insights.sbomify.com/CVE-2009-5147/"}
