An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-36231 exists.\n\nAffected packages and fixed versions:\n- pdf_info (RubyGems): affected all versions up to 0.5.3; no fix listed\n- pdf_info (RubyGems): affected all versions up to 0.5.3; no fix listed\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-2022-36231/ (Markdown: https://insights.sbomify.com/CVE-2022-36231/index.md)","id":"CVE-2022-36231","markdown":"https://insights.sbomify.com/CVE-2022-36231/index.md","name":"CVE-2022-36231","record":{"aliases":["GHSA-9fh3-j99m-f4v7"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby PDF library","requires_auth":"none","summary":"Attackers can execute arbitrary commands via the pdf_info Ruby library due to unsafe backtick usage.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pdf_info","vendor":"newspaperclub"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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":"pdf_info 0.5.3 is vulnerable to Command Execution because the Ruby code uses backticks instead of Open3.","ecosystems":["RubyGems"],"exploits":{"exploitdb":0,"first_seen":"2022-10-26","github_poc":1,"max_poc_stars":6,"metasploit":0,"nuclei":0,"refs":[{"date":"2022-10-26T14:51:57Z","kind":"github_poc","ref":"https://github.com/affix/CVE-2022-36231","stars":6,"title":"pdf_info \u003c= 0.5.3 OS Command Injection"}],"tier":"weaponised"},"has_fix":false,"headline":"Code injection in pdf_info","id":"CVE-2022-36231","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":null,"products":[],"type":"command_injection","year":"2022"},"n_packages":2,"n_references":4,"next":{"headline":"Memory corruption in n/a","id":"CVE-2022-36233"},"packages":[{"ecosystem":"RubyGems","fixed":[],"introduced":["0"],"last_affected":["0.5.3"],"package":"pdf_info","purl":null,"source":"GHSA-9fh3-j99m-f4v7"},{"ecosystem":"RubyGems","fixed":[],"introduced":["0"],"last_affected":["0.5.3"],"package":"pdf_info","purl":"pkg:gem/pdf_info","source":"GHSA-9fh3-j99m-f4v7"}],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2022-36228"},"products":["n/a"],"published":"2023-02-23","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-03-13","vendors":["n/a"]},"summary":"Attackers can execute arbitrary commands via the pdf_info Ruby library due to unsafe backtick usage.","url":"https://insights.sbomify.com/CVE-2022-36231/"}
