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-2009-4418 in the wild and no public exploit code.\n\nAffected product: Php Php. 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-2009-4418/ (Markdown: https://insights.sbomify.com/CVE-2009-4418/index.md)","id":"CVE-2009-4418","markdown":"https://insights.sbomify.com/CVE-2009-4418/index.md","name":"CVE-2009-4418","record":{"aliases":["GHSA-37px-x6g4-3pm2"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP language","requires_auth":"none","summary":"Attackers can cause denial of service in PHP applications by submitting deeply nested serialized data, leading to excessive resource consumption.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"php","vendor":"php"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"The unserialize function in PHP 5.3.0 and earlier allows context-dependent attackers to cause a denial of service (resource consumption) via a deeply nested serialized variable, as demonstrated by a string beginning with a:1: followed by many {a:1: sequences.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-2009-4418","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"php:php","products":["php:php"],"type":"denial_of_service","year":"2009"},"n_packages":0,"n_references":2,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2009-4419"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2009-4417"},"products":["n/a"],"published":"2009-12-24","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2012-2688","kev_date_added":null,"published":"2012-07-20"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2012-2376","kev_date_added":null,"published":"2012-05-21"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2011-3268","kev_date_added":null,"published":"2011-08-25"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2009-4143","kev_date_added":null,"published":"2009-12-21"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-5557","kev_date_added":null,"published":"2008-12-23"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-2050","kev_date_added":null,"published":"2008-05-05"},{"cvss_score":10,"headline":"Command injection in n/a","id":"CVE-2008-2051","kev_date_added":null,"published":"2008-05-05"}],"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":"2024-09-17","vendors":["n/a"]},"summary":"Attackers can cause denial of service in PHP applications by submitting deeply nested serialized data, leading to excessive resource consumption.","url":"https://insights.sbomify.com/CVE-2009-4418/"}
